Noise regulation

noise regulation law, noise regulation
Noise regulation includes statutes or guidelines relating to sound transmission established by national, state or provincial and municipal levels of government After the watershed passage of the United States Noise Control Act of 1972,1 other local and state governments passed further regulations

A noise regulationcitation needed restricts the amount of noise, the duration of noise and the source of noise It usually places restrictions for certain times of the day2

Although the UK and Japan enacted national laws in 1960 and 1967 respectively, these laws were not at all comprehensive or fully enforceable as to address generally rising ambient noise, enforceable numerical source limits on aircraft and motor vehicles or comprehensive directives to local government

Historyedit

A sound level meter, a basic tool in measuring sound

United States initial legislationedit

In the 1960s and earlier, few people recognized that citizens might be entitled to be protected from adverse sound level exposure Most concerted actions consisted of citizens groups organized to oppose a specific highway or airport, and occasionally a nuisance lawsuit would arise Things in the United States changed rapidly with passage of the National Environmental Policy Act NEPA in 1969 and the Noise Pollution and Abatement Act, more commonly called the Noise Control Act NCA, in 1972 Passage of the NCA was remarkable considering the lack of historic organized citizen concern However, the United States Environmental Protection Agency EPA had testified before Congress that 30 million Americans are exposed to non-occupational noise high enough to cause hearing loss and 44 million Americans live in homes impacted by aircraft or highway noise3456

NEPA requires all federally funded major actions to be analyzed for all physical environmental impacts including noise pollution, and the NCA directed the EPA to promulgate regulations for a host of noise emissions Many city ordinances prohibit sound above a threshold intensity from trespassing over property line at night, typically between 9 pm to 7 am, and during the day restricts it to a higher sound level; however, enforcement is uneven Many municipalities do not follow up on complaints Even where a municipality has an enforcement office, it may only be willing to issue warnings, since taking offenders to court is expensive A notable exception to this rule is the City of Portland, Oregon, which has instituted an aggressive protection for its citizens with fines reaching as high at $5000 per infraction, with the ability to cite a responsible noise violator multiple times in a single day7

Japanedit

Japan actually passed the first national noise control act, but its scope was much more limited than the US law, addressing mainly workplace and construction noise8

Follow-up on initial US lawsedit

Initially these laws had a significant effect on thoughtful study of transportation programs and also federally funded housing programs in the United States They also gave states and cities an impetus to consider environmental noise in their planning and zoning decisions, and led to a host of statutes below the federal level Awareness of the need for noise control was rising In fact, by 1973 a national poll of 60,000 US residents found that sixty percent of people considered street noise to have a "disturbing, harmful or dangerous" impact9

This trend continued strongly throughout the 1970s in the US, with about half of the states and hundreds of cities passing substantive noise control laws Noise regulation subsided sharply in 1981, when Congress ended funding for the NCA EPA had pre-empted lower levels of government from regulating sources, so states could not legislate standards such as for truck noise emissions Thus, in areas where the federal government had failed to promulgate clear standards such as aircraft noise, no further progress could be made except by the Federal Aviation Administration FAA, which has an inherent conflict of interest regarding noise regulation

Nevertheless, some states continued to act California carried out an ambitious plan to require its cities to establish a "Noise Element of the General Plan," which provides guidance for land planning decisions to minimize noise impacts on the public Many cities throughout the US also have noise ordinances, which specifies the allowable sound level that can cross property lines These ordinances can be enforced with local police powers10

Europe and Asiaedit

Several European countries emulated the US national noise control law: Netherlands 1979, France 1985, Spain 1993, and Denmark 1994 In some cases unlegislated innovations have led to quieter products exceeding legal mandates for example, hybrid vehicles or best available technology in washing machines Environmental noise is a special definition in the European directive 2002/49/EC article 101

The US activities lag by 10 to 20 years behind most European countries Russia, China and undeveloped countries lag even further behindcitation needed

National controls in the US programedit

After the passage of the NCA, EPA promulgated regulations setting maximum noise limits on a gamut of motor vehicles, industrial machinery and household appliances The Agency conducted extensive testing and consulted with industry on the practicality of manufacturing quieter devices EPA's efforts had an influence on the future of a quieter generation of machines However, roadway noise and aircraft noise account for the lion’s share of noise emissions, and the EPA standards for those vehicles pre-empted states from further regulating In the case of aircraft noise, FAA had veto power over EPA recommendations, so those standards never pushed the envelope

In the case of motor vehicles, states could not exact a greater standard for enforcement against an individual vehicle, and interstate commerce priorities meant that guidelines for total noise exposure along federally funded highways remained guidelines rather than strict standards Despite these drawbacks, states and the public at large had a superb weapon in the review of proposed major transportation systems in the form of NEPA and the NCA In many cases courts were able to enforce the intent of those laws to secure the redesign of roadways and transit systems to provide more noise mitigation or to select an alternative of lesser impact than the original project; in many other cases, the highway agencies simply listened to public input and acoustical scientists before finalizing highway and transit designscitation needed

In the case of airport expansions, courts consistently upheld the sovereignty of the FAA over the EPA, in allowing air traffic needs to be met over environmental concerns Thus airports were required to study impacts of air traffic and facilities expansions and provide detailed noise contour maps, but in the final analysis the EPA exposure guidelines only advisory in nature To respond to the shortcomings of the voluntary guidelines, FAA created a well funded program to insulate thousands of homes in the vicinity of major airports The program was based upon computer modeling of alternative insulation strategies, calculated on a house-by- house basis While this program did nothing to mitigate exterior sound levels, it benefited residential interiors significantlycitation needed

US State and local planningedit

States passed two different types of legislation starting in the 1970s, echoing the federal lead in noise control First, many states, with California in the vanguard on a state level, began requiring each municipality and county to have a Noise Element of the General Plan, a substantial noise data base and blueprint for making land use decisions in that jurisdiction The Noise Element became an integral part of the municipal or county General Plan, especially in California This document compiled a comprehensive set of measurements setting forth existing sound levels, frequently in the form of sound level contour maps to illustrate where varying sound levels fall relative to land use categories11

The Noise Element further states goals for each land use class and even numerical planning standards in order to evaluate future development proposals with regard to noise pollution Technical analysis of urban highway noise had advanced by the early 1970s to allow intricate analysis of urban planning decisions in order to plan and design urban highways and support associated noise regulations11

Cities and counties in the US, who either fell under state mandates or who voluntarily chose to control noise through land use decisions, were active in categorizing sound levels and seeking development strategies that would minimize the number of persons exposed to harmful levels of primarily motor vehicle noise Portland, Oregon continues to innovate through its almost 35-year-old Noise Control Office at the City's Bureau of Development Services Today its code is still one of the only comprehensive codes in the US that not only regulates based on a given decibel level, but also includes sound limitations based on the specific pitch or frequency of the given noisecitation needed

Local noise ordinances in US and Europeedit

Local ordinances are principally aimed at construction noise, power equipment operated by individuals and unmuffled industrial noise penetrating residential areas Thousands of US cities have prepared noise ordinances that give noise control officers and police the power to investigate noise complaints and enforcement power to abate the offending noise source, through shutdowns and fines10 In the 1970s and early 1980s there was even a professional association for noise enforcement officers called NANCO, "National Association of Noise Control Officials"

Today only a handful of properly trained Noise Control Officers remain in the United States A typical noise ordinance sets forth clear definitions of acoustic nomenclature and defines categories of noise generation; then numerical standards are established, so that enforcement personnel can take the necessary steps of warnings, fines or other municipal police power to rectify unacceptable noise generation Ordinances have achieved certain successes but they can be thorny to implement Many European cities are still treating noise as the US did in the 1960s, as a nuisance and not as a numerical standard to be achievedcitation needed

  • Effects of Noise on Health and Welfare

12131415

One obligation of a community is to protect its citizens from adverse environmental influences Noise is one of these factors, Noise has documented effects on people, they can be divided into three types The first type is a physical effect that directly and adversely effects a person's health Hearing loss and vibration of bodily components are examples The second type is a physiological effect that adversely effects a person's health; heightened blood pressure and general stress response are examples The third type is psychological that adversely effects a person's welfare; examples are distraction, annoyance, and complaint The only feasible legal basis for a community’s right to control noise is based on these adverse health and welfare effects It is clearly easier to uphold the constitutionality of a noise ordinance in a court of law if it can be shown that it is based on health and welfare concerns The following is a short list of recognized effects of noise that can be addressed as a reason for a noise ordinance

Excess non-Occupational noise exposure, hearing loss on both public and private property, speech interference on both public and private property, audio interference on both public and private property, and sleep interference on mostly private property16

Some legal considerations in the United Statesedit

There are several fundamental issues that shape the legality, effectiveness and enforceability of any community noise regulation

Preemptionedit

The federal government has preempted certain areas of noise regulation They can be found in the Code of Federal Regulations under the EPA Noise Abatement Programs;1718 Parts 201 to 205 and 211 cover railroads, motor carriers in interstate commerce, construction equipment, motor vehicles They require product labeling and prohibit tampering with noise control devices Communities may enact regulations that are no more strict than the federal ones so that local enforcement can be carried out They can enact curfews and restrict vehicle use in established zones such as residential Any restriction on interstate motor carriers or railroads may NOT be for the purpose of noise control States have police powers granted by the Constitution They may also enact regulations that are no more strict than federal regulations They may also preempt local ordinances California 19 and New Jersey20 have comprehensive noise codes that communities must meet Many states required that local ordinances be no more strict than the state code whether such code exists or not One relatively common preemption is protection of shooting ranges from noise regulation or litigation21 and right to farm laws that protect agricultural areas from nuisance litigation by encroaching residential areas22

Constitutional vaguenessedit

In one case, the United States Supreme Court has said Void for vagueness “It is a basic principle of due process Amendment V that an enactment is void for vagueness if its prohibitions are not clearly defined Vague laws offend several important values First, because we assume that man is free to steer between lawful and unlawful conduct, we insist that laws give the person of ordinary intelligence a reasonable opportunity to know what is prohibited, so that he may act accordingly Vague laws may trap the innocent by not providing fair warning Second, if arbitrary and discriminatory enforcement is to be prevented, laws must provide explicit standards for those who apply them A vague law impermissibly delegates basic policy matters to policemen, judges, and juries for resolution on an ad hoc and subjective basis, with the attendant dangers of arbitrary and discriminatory application Third, but related, where a vague statute abuts upon sensitive areas of basic First Amendment freedoms, it operates to inhibit the exercise of those freedoms the chilling effect In one case,23 the court declared that numerical sound levels were constitutional as well as the term plainly audible provided it was associated with a reasonable distance Two requirements for a noise ordinance provision is that:

  1. provide fair warning
  2. avoid the possibility of arbitrary enforcement

Free Speechedit

Examples are: slander, hate speech, and falsely calling "fire" in an assembly Generally, the time, place, or manner of restrictions must:

  1. be content neutral
  2. be narrowly tailored
  3. serve a significant government interest
  4. leave open alternative channels of communication

One example24 concerned protesters outside an abortion clinic The US Supreme Court stated that limitations placed on noise making were necessary to ensure the well-being of patients

Overbreadthedit

The US Supreme Court has addressed the issue of too much regulation by defining overbreadth as: A clear, precise enactment may nevertheless be overbroad if, in its reach, it prohibits constitutionally protected conduct One means to avoid being overbroad is by having provisions that are specific so that potential violators are given fair warning of what is prohibited In one case 25 the court ruled that the specificity of the city ordinance Section 17-35 regulating school verbal protests was not constitutionally vague, gave fair warning, and was not an invitation to arbitrary enforcement and so was not overbroad, despite the implied limitation on free speech

Nuisanceedit

Nuisances are part of tort law Torts are civil wrongs whether intentional or accidental from which injury occurs to another Nuisances can be public or private A public nuisance is an unreasonable interference with a right common to the general public while a private nuisance is an interference with a person's enjoyment and use of his land Black's Law Dictionary defines a nuisance as that which annoys and disturbs one in possession of his property, rendering its ordinary use and occupation physically uncomfortable to him It defines a private nuisance as:anything done to the hurt or annoyance of the lands, tenements, or hereditaments of another As distinguished from public nuisance, it includes any wrongful act which destroys or deteriorates the property of an individual or of a few persons or interferes with their lawful use or enjoyment thereof, or any act which unlawfully hinders them in the enjoyment of a common or public right and causes them a special injury different from that sustained by the general public The word nuisance is connected closely with the word disturbance which is used extensively in many noise ordinances A definition below further restricts the meaning to noise disturbance Nuisance law applies to both community noise regulation as well as private suits brought to court to reduce noise impact

Enforceabilityedit

Care must be taken in writing a subjective noise provision so that it overcomes the objections listed above Care must be taken when writing an objective noise provision to make sure that the sound levels are physically realizable For example, requiring the maximum sound level of an automobile to be 40 dBA or the maximum sound level in a residential zone to be 30 dBA opens the provision to an enforceability challenge

Confiscationedit

Confiscation is the taking of private property for public use without compensation It may occur legally when the government seizes property used in illegal practices Confiscation may occur without an arrest of a person because it is seen as an arrest of property, rather than a person, and the necessity of finding a party guilty is not required in all cases In many cases, the guilt or innocence of the property owner is irrelevant and the government need not prove anything beyond a reasonable doubt In order to seize property, there must be either a warrant or a showing of probable cause The mere showing of probable cause to support the forfeiture of an individual’s property has been a controversial issue Court opinion varies, but probable cause most often means that the government need only demonstrate reasonable grounds for the belief that the property is properly subject to forfeiture, which can be supported by something less than prima facie proof, but more than mere suspicion The Peoria, Illinois noise ordinance Sections 15-75 and 15-77 allows confiscation of vehicles that emit excessive sound caused by sound producing devices Colorado Springs, Colorado Section 98102 permits confiscation of sound producing devices

Four Types of Noise Regulationedit

26 Fixed sound sources must be treated differently than moving sources In the former case, the listener is normally defined while for moving sources it is not Historically, regulations were enforced by the subjective judgment of an enforcing officer With the advent of sound measuring equipment, the judgment can be based on measured sound levels Most comprehensive noise ordinances contain four types of provisions

Subjective Emission These regulations allow an official to decide if the output of a sound source is acceptable without recourse to sound measurements and without regard to the presence of a specific listener Regulations with plainly audible terms on public property as a criterion are examples

Subjective Immission These regulations allow an official to decide if the sound received by a listener is acceptable without recourse to sound measurements and without regard for the specific sound power generated by the source Regulations with plainly audible or noise disturbance terms on private property as a criterion are examples

Objective Emission These regulations require an official to measure the output of a sound source to determine whether it is acceptable without regard to the presence of a specific listener Regulations with specific maximum sound output levels for motor vehicles are examples

Objective Immission These regulations require an official to measure the sound received by a listener to determine whether it is acceptable without regard to the specific sound power generated by the source Regulations with maximum allowable sound levels on property lines are examples

Some Definitions used in the United Statesedit

many communities have definitions that are local to them, such as those defining motor vehicles and sound levels and sound level measurements Some that have been added to make noise enforcement more specific are listed here26

Engine Braking Deviceedit

A compression braking device installed on large motor vehicles to assist in reduction, or control, of vehicle speed When activated, the engine converts from a power source to a power absorber by converting the engine into an air compressor

Muffleredit

Any device for the abatement of sound emission while permitting the transfer of gas A muffler is considered to be in good working order if the sound reduction is equal to, or greater than, that of the original equipment

Noise Disturbanceedit

Any sound or vibration which:

  1. may disturb or annoy reasonable persons of normal sensitivities or;
  2. causes, or tends to cause, an adverse effect on the public health and welfare or;
  3. endangers or injures people or;
  4. endangers or injures personal or real property

This can also be defined as noise nuisance

Place of Public Entertainmentedit

Any location, exterior, or interior, to a building that regularly permits public entrance for entertainment purposes For this purpose, “public” means citizens of all types, including but not limited to, children, and private or public employees

Plainly Audible Soundedit

Any sound for which the information content is unambiguously communicated to the listener, such as, but not limited to, understandable speech, comprehension of whether a voice is raised or normal, repetitive bass sounds, or comprehension of musical rhythms, without the aid of any listening device

Powered Model Vehicleedit

Any self-propelled airborne, water-borne, or land-borne, plane, vessel, or vehicle, which is not designed to carry persons, including, but not limited to, any model airplane, boat, car, or rocket

Real Property Boundaryedit

An imaginary line along the ground surface, and its vertical extension, which separates the real property owned by one person from that owned by another person, but not including intra-building real property divisions

Sound Reproduction Deviceedit

Any device, instrument, mechanism, equipment or apparatus for the amplification of any sounds from any radio, phonograph, stereo, tape player, musical instrument, television, loudspeaker or other sound-making or sound-producing device or any device or apparatus for the reproduction or amplification of the human voice or other sound

Vibration Perception Thresholdedit

The minimum ground or structure borne vibrational motion necessary to cause a person of normal sensitivity to be aware of the motion through contact, hearing, or through visual observation of moving objects

Ordinance Provisions for Stationary Sources in the United Statesedit

there are three levels of regulation for stationary sound sources The most basic is the general one associated with noise disturbance See Noise Disturbance below It is a very broad subjective immission control that has evolved from earlier disturbance of the peace provisions Subjectivity can lead to arbitrary enforcement The next level of regulation is less broad; it is an objective immission control that uses specific levels of sound considered to be a noise disturbance Arbitrary enforcement is reduced See Maximum Permissible Sound Levels below In both cases, however, the person creating the sound may not be aware that his actions are in violation The concept that a potential violator should have fair warning that his actions are in violation has led to provisions that address specific noise problems The sections below list those that are found in community noise ordinances26

Air Conditioning, Heating and Pool Equipmentedit

This provision is a subjective immission control An evaluation of the noise disturbance is made at the listener without a sound level meter This provision is mostly applied in residential zones such as homes, apartments and condominiums Albuquerque, NM Article 9-9 requires that such units the maximum permissible sound levels Se section below and recommend that those units be placed away from other residential units or on roof tops to diminish impact

Airport and Airport Operationsedit

Community control of airport created noise is limited to those sounds not related to flight operations The community is able to control the land use around the airport however

Animalsedit

This provision is a subjective immission control Most relate to barking dogs and put an upper time limit for continuous sound from them New Jersey Chapter 13:1G considers a violation if the sound is continuous for more than 5 minutes or intermittent for more than 20 minutes They also consider it a defense to violation if the animal is provoked to bark Connecticut Chapter 442exempts animal sounds while Anchorage, AK Chapter 1570 requires that continual violations permit the animal to be taken and put out for adoption

Authorized Outdoor Discharge of Firearms and Shooting Rangesedit

This provision contains only a curfew since most states protect shooting ranges from liability for noise disturbance It can include a curfew requirement and a requirement for a public hearing if expansion of the range is desired The provision may prohibit other weapons such as rocket propelled projectiles but may exempt unpowered weapons such as arrows South Carolina title 31 Chapter 18 requires that a sign stating SHOOTING RANGE-NOISE AREA be placed on all primary roads Arizona ARS 17-602 places a curfew from 10pm to 7 am It also allows a tradeoff between the number of events and the maximum permitted sound level New York Chapter 150 also trades off overall levels with the duration of the sounds Colorado Article 25-12-109 declared that noise restrictions on shooting ranges is a detriment to public health, welfare, and morale

Condominiums and Apartmentsedit

This provision is a subjective immission control It is designed to limit the noise disturbance between living units as defined by an enforcement official One criterion used to evaluate that disturbance is use of plainly audible but at the location of the listener instead of at a specific distance However, Charlotte, NC Sec 15-69 limits indoor levels to 55 dBA be tween 9am to 9pm and 5 dB less at other times, but only from sound reproducing devices Salt Lake Valley Health Department Chapter 4, Minneapolis, MN Chapter 389, and Albuquerque, NM Article 9 use levels to existing ambient to define a violation Albuquerque NM and Omaha, NE Chapter 17 require that intruding sounds not be audible Burlington, VT Chapter 18 requires that renters be supplied with the city noise ordinance

Constructionedit

This provision can be both a subjective immission control and an objective emission control Normally there are daily curfews and in some case weekend curfews The subjective aspect is to prevent noise disturbance in the adjacent community The objective aspect is to control the sound output of specific machines There are four major sources of site noise: 1 direct sound from continually operating equipment such as air compressors; 2 intermittent sound from equipment such as jack hammers;3backup alarms; and 4 hauling equipment such as trucks Air compressor noise is regulated by CFR 204 and backup alarms are regulated by CFR 1926 Boston, MASection 16-264 permits construction on weekdays between 7am and 6 pm Madison, WI Chapter 2408 limits sound levels to 88 dBA at 50 Feet Miami, FL Section 36-6 considers the noise a noise disturbance if it occurs between 6pm and 8am during the week and any time on Sunday Dallas, TX Section 30-2 9 permits construction in residential zones from 7am to 7pm on weekdays, from 9am to 7pm on Saturdays and Holidays, and prohibits construction on Sundays Albuquerque,NM Section 9-9-8 has a more complex control It prohibits construction and demolition within 500 feet of noise sensitive properties residences included if the equipment sound control devices are less effective than the original equipment and if noise mitigation measures are not used when the levels exceed 90 dB weighting not specified or more than 80 dB during the day for three days

Domestic and Commercial Power Toolsedit

This provision is a subjective immission control with a curfew It is used in residential zones as well as in commercial areas abutting residential zones Portland, OR Title 1810030 has several ways to handle these tools They separate outdoor and indoor use to different maximum levels at the property line They have a night curfew and separate 5 HP tools from higher powered tools Madison WI Chapter 2408 has similar HP restrictions Albuquerque, NM Title 9-9-7 restricts locations to more than 500 feet from residential and noise sensitive zones Dallas, TXSec 30-2 exempts lawn maintenance tools during daylight hours Green Bay, WI Subchapter II – 27201 exempts snow removal tools

Explosives, Firearms, Impulsive Sources, and Similar Devicesedit

This provision is a subjective immission control with a curfew It is for impulsive sound sources that are not associated with construction activities or shooting ranges Many communities use the Maximum Permissible Sound Levels criterion see below, with a correction for the character of the sound Illinois sets maximum blasting levels by land use zone and in three time categories Portland, OR Section 1810010F limits levels to 100 dB peak from 7am to 10pm and 80 dB peak from 10pm to 7 am

Fracking Operationsedit

Hydraulic Fracturing operations generate site sound as well as vehicle sound and several different provisions are required to control it Federal law regulates the levels of certain site machinery A subjective immission control or a objective immission control can be applied to surrounding neighborhoods See maximum Permissible Sound Levels Motor vehicle sound is mostly off-site so vehicle noise regulations are applicable See Motor Vehicles on a Public Right-of-way The State of New York has announced a statewide ban on such operations Buffalo, NY and Pittsburgh, PA have announced a ban Colorado has numerous activities to stop fracking

Funeralsedit

This is a subjective emission control to reduce the excessive shouting and protests that can surround funeral proceedings It makes use of the plainly audible term and so adds a distance criterion There are certain groups, particularly those that object to involvement in foreign wars, who believe it is an obligation to disrupt and picket funerals, especially those of deceased military veterans This provision must not infringe on Constitutionally protected free speech Illinois h720 ILCS 5/26 6has a comprehensive provision covering more aspects of this event than noise They failed to use “plainly audible” which is narrower than “audible” UtahSection 76-9-108 restricts disruptive activity to beyond 200 feet

Loading and Unloading Operationsedit

This provision is a subjective immission control with a curfew Operations in commercial facilities can impact adjacent residential zones Los Angeles, CA Section 11403 places a curfew on such operations between 10pm and 7am but only if the source is within 200 feet of a residence Chicago, IL Section 11-4-2830 permits night operations unless they create a noise disturbance Hammond, IN Section 626 prohibits noise disturbance between 7pm and 7am

Maximum Permissible Sound Pressure Levelsedit

This provision is an objective immission control It requires the measurement of sound levels at or beyond a property line and its vertical extension There are several methods for implementing such a provision:

  1. It may not permit any exceedence or may permit exceedence only for a percentage of the measurement period
  2. It may require the measurement method to be instantaneous, such as dBA or time-averaged, such as Energy Equivalent Level Leq
  3. It may be a fixed level limit, such as 55 dBA, or it may be a level relative to the ambient sound, such as 5 dBA above the ambient
  4. It may require measurement of the frequency spectrum, such as one octave bands, or A-weighting, such as dBA
  5. It may define different maximum levels based on zoning criteria, such as residential, commercial, or industrial
  6. It may define different maximum levels based on time-of-day or day-of-week, such as reduced maxima during night hours or on weekends
  7. It may require reduction of maximum levels based on the character of the sound, such as intermittent or impulsive
  8. It may exempt certain classes of sound sources, such as shooting ranges, farm equipment, emergency equipment, railroads, or licensed activities

most noise ordinances set maximum levels for two time periods: Day 7am to 10pm and Night 10pm to 7am27 San Diego Article 925sets three periods: Day 7am to 7pm, Evening 7pm to 10pm, and Night 10pm to 7am and exempts industrial zones from time based restrictions Seattle, WA Chapter 2508 sets two time periods but changes 7am to 9am on weekends and holidays Several states have maximum permissible land use sound levels in dBA Most have Day and Night periods and three use categories: residential, Commercial and Industrial Washingtonvague Chapter 70107 sets maximum levels in dBA but allows 5 dBA more if the sound is only 15 minutes in an hour, or 10 dBA for 5 minutes in an hour Numerous cities have fixed levels, permitting excess levels for short times eg, Dallas, TX, Chapter 30 while others use Leq Lincoln, NE, Chapter 824 Los Angeles, CA Chapter XI uses a relative level with a stated but presumed ambient New York City, NY Chapter 19 requires Leq measurements to be made over one hour Atlanta, GA vague limits impulsive sound to 100 dBC at property lines, while most reduce the maximum level by 5 dB for pure tones and impulsive sounds

Motor Vehicle or Motorboat Repairs and Testingedit

This provision is a subjective immission control with a curfew If the activity is done in a residential zone, the Domestic Tools provision can be applied for the repairs, but this provision also is used for the testing phase of any repairs Los Angeles, CA Section 11401 covers this violation in three ways The first is application of the noise disturbance provision in residential districts between the hours of 8 pm to 8 am The second is being plainly audible at a distance of 150 feet or more in residential districts between the hours of 8 pm to 8 am The third is exceeding the presumed ambient by 5 dB Hammond, IN Section 627 prohibits this activity as a noise disturbance at any time

Noise Disturbance Prohibitededit

This provision is a subjective immission control This provision is generic in that it covers all events that are considered disturbing by a listener, with or without measurement The strength of this provision is that it covers situations not contemplated in a noise ordinance and can be used as backup for more specific provisions The weakness is that it may not give fair warning, may lead to arbitrary enforcement on the part of the regulator, or permit unreasonable demands by a listener

Noise Sensitive Zonesedit

This provision is a subjective immission control It is used to reduce levels of both stationary and vehicular sound sources around hospitals, schools, and other noise sensitive locations To provide fair warning visible signs must be posted It is possible to have an extensive list For example, if churches are on the list and the community has many of them, signage, compliance, and enforcement can be a problem In modern hospital environments, helicopter sound is exempt

Places of Public Entertainmentedit

This provision is an objective immision control It regulates the site of the sound source while the Sound Reproduction Devices section regulates the devices that create the sound It can regulate the sound levels received by involuntary listeners in the surrounding community as well as the sound levels received by voluntary listeners If the latter aspect is incorporated, limiting internal sound levels often resolves community noise impact Los Angeles Article 2,Section 11206requires warning signs and limits noise exposure to 95 dBA at any position normally occupied Seattle, WA considers the sound emitted to be in violation if the sound is plainly audible within a dwelling from 10 pm to 7am; the need for a sound level meter is avoided Chicago, IL limits received sound levels to 55 dBA inside a residential dwelling unit but if the ambient is greater, the limit is 65 dBA If outdoors, the limit is conversational level at 100 feet from the property line If the building is set back 20 feet from the property line, the allowable level is 84 dBA! Both of Chicago’s limits apply from 10 pm to 8 am Salt Lake health Department, UT sets the limit at 95 dBA at a position that would normally be occupied by a patron and 100 dBA at other positions They also require a sign stating WARNING: SOUND LEVELS ON THIS PREMISE sic MAY CAUSE PERMANENT HEARING DAMAGE HEARING PROTECTION IS AVAILABLE Anchorage, AK Section 1570060B12 sets maximum levels for any patron at 90 dBA

Powered Unmanned Vehicles or Enginesedit

This provision is a subjective immission control with a curfew It has been used to regulate the sound of model aircraft on both private and public property It applies to airborne, water-borne, and land-borne, unmanned vehicles It makes no distinction between model vehicles and full-size unmanned vehicles it applies also to the engines of those vehicles Most regulations pertained to private unmanned vehicles, normally restricted to local open fields The development of drones with microphones, cameras and GPS has opened the door to commercial use over wider private and public properties Since federal preemption of drone use will likely occur, it is important for this provision to make the distinction Salt Lake Health Department Section 4515 limits activity to 800 feet from a dwelling between 10 pm and 7 am, or if it cases a noise disturbance Atlanta, GA Section 74-136b uses the plainly audible criterion across a residential property line, on a public property from 10 pm to 7 am on weekdays or from 10 pm to 10 am on weekends or holidays for any sound source

Propane Cannonsedit

This provision is a subjective immission control with a curfew A propane cannon is used to keep animals and birds from destroying commercial crops In large fields, many are used and fired as frequent intervals The sound levels are equivalent to the firing of a small artillery cannon The provision may contain requirements that limit the number of cannons permitted in a specific area and the number firings per hour for each cannon many states have a Right to Farm Act that limits nuisance litigation Florida stated that it was a purpose of their act to protect reasonable agricultural activities conducted on farm land from nuisance suits They also added a section that limited expand of operations without consideration of noise Fairfax County, VA Sections 105-4-4 and 108-5-1 require agricultural operation to meet maximum land use regulations and prohibit unnecessary noise British Columbia Ministry of Agriculture Farm Nuisance Noise document have developed a comprehensive set of rules for cannon use

Public Address Systemsedit

This provision is a subjective immission control It can contain a plainly audible term or a curfew It is applied to commercial facilities using a sound system to deliberately propagate mostly speech, but also music Most cities have provisions relevant to this subject Lakewood, CO Sections 95206 and 0952160 used plainly audible as a regulatory tool and prohibits the sounding of bells, or chimes from 10pm to 7am Charlotte, NC Section 15-69a4 limits levels to 60 dBA at 50 feet from 9am to 9pm and 50 dBA at other times Indianapolis, IN Section 391-505 addresses broadcasts from aircraft Connecticut Section 22a-69-17 exempts bells, carillons, and chimes from religious facilities

Sound Reproduction Devicesedit

This provision is subjective immission control It may contain a numerical level or a plainly audible term and a curfew it is applied to specific sources of sound as opposed to any location at which the sound is created It is applied primarily to amplified sound sources Older provisions listed several items such as televisions, phonographs, etc Changing the title to the above addresses the real issue and allows for novel sound production devices Numerous communities have provisions for these devices; many use plainly audible as the criterion, such as Omaha, NE Section 17-3 and Buffalo NY Section 293-4

Stadiums and Outdoor Music Festivalsedit

This provision can be either a subjective or objective immission control with a curfew The subjective aspect relates to noise disturbance in the local community The objective aspect limits the acceptable sound level in the local community Illinois Environmental Protection Act 41525 exempts certain stadiums and exempts festivals, parades, or street fairs Colorado Spring, CO Section 98101 has similar exemptions, but limits the sound levels to 80 dBA at residential locations

Stationary Emergency Signaling Devicesedit

This provision is an emission control with a list of devices that are exempt It can have a term that limits the time periods in which emergency alarms may be tested It can have a term that limits the activation time of burglar or fire alarms Chicago, IL Section 11-4-2815 limits the time for tests to 4 minutes between 9am and 5pm Oregon Chapter 467 prohibits sound when an emergency vehicle is stationary

Stationary non-Emergency non-Safety Signaling Devicesedit

This provision is an emission control that limits the activation period of alarms and restricts activation to a specific time-of-day or day-of-week Los Angeles, CA prohibits the sounding if the signal can be heard at 200 feet or more Chicago, IL Section 11-4-2820 considers the sound to be a noise disturbance in residential areas if the sound exceeds 5 minutes in any hour; steam whistles are exempt Albuquerque, NM Section 9-9-12 restricts levels to 5 dB over the ambient at a property line and applies maximum permissible residential level as well as plainly audible restrictions at night

Street Salesedit

This provision is a subjective immission control with a curfew Boston, MA Section 16-22 prohibits street sales near schools or churches if there is a “disturbance of the peace” Hammond, IN Section 624 places a curfew between 6 pm and 9 am

Tamperingedit

This provision prevents the modification of muffling devices that increase the emitted sound It can also be used to prevent the commercial sale of such mufflers Most states and communities have prohibitions on tampering with noise reduction devices whether stationary or moving Salt Lake County health Department Section 4510 prohibits modifications of mufflers that increase sound levels and prohibits tampering with noise rating labels See Section below on Adequate Mufflers

Vibrationedit

This provision is a subjective emission control Noise disturbance caused by vibration comes in three forms One is contact with vibrating surfaces, the second in auditory, and the third is the observation of surrounding objects movement Objectively regulating vibration is difficult so this provision makes use of the Vibration Perception Threshold Railroad caused vibration is preempted by federal law CFR 201 Chicago, IL Section 11-4-2910 uses the perception threshold method Dallas, TX requires measurement of low frequency vibration Maryland uses the definition of noise to include sound and vibration at sub-audible frequencies

Wind Turbinesedit

The sound created by wind turbines is caused by the blade rotation similar to aircraft propellers Because the rotation rate is low, the frequency is also low, but the large size of many can result in disturbing sound levels, particularly in high wind areas28 Most local control is done by advantageous site planning New Hampshire Title LXIV, Section 674:63 sets a sound level limit of 55 dB when measured at the site property line, allowing for exceptional events, such as storms Studies have declared that wind noise can have a negative effect on health29

Ordinance Provisions for Moving Vehicles in the United Statesedit

Stationary sources have fixed positions, so it is possible to define the listeners and therefore immission controls are appropriate Motor vehicles are moving sources so it is not possible to define any specific listeners so emission controls are appropriate There are exceptions to this distinction Construction equipment, and some recreation vehicles, move within a bounded area and can be considered to be time varying fixed sources Standing motor vehicles can radiate sufficient sound to create noise disturbance These must be treated by specific provisions26

Adequate Mufflers or Sound Dissipation Devicesedit

This provision is an objective emission control Unlike the Tampering provision, this is specific to motor vehicles It requires that a vehicle muffler not create more sound than the original equipment which has been measured It prohibits any modification or replacement that increases the sound emission beyond that of the original equipment It prohibits the sale of mufflers that do not meet original equipment standards Many states have requirements that a muffler shall be in good working order which is not specific enough California Section 271501 requires that a retail seller that sells a product in violation of the muffler regulation must install a replacement muffler that meets the regulation and must reimburse the purchaser for the expense of replacement

Airboats and Hovercraftedit

This provision is both an "objective emission control and a subjective immission control It can set a maximum sound level at a specified distance typically 50 feet It can have a curfew It can be based on noise disturbance in the community It can also require the use of ear protectors on passengers Unlike motorboats, the sound generators on these vehicles are airborne, resulting in more noise impact Florida Section 32765 requires a maximum level of 90 DBA Maine Title 12 Section 13068-Ahas three levels: operating, operating test and stationary test

Engine Braking Devicesedit

This provision is an emission control It can restrict brake use for only safety purposes and by defining restricted areas It can require that mufflers be maintained to keep emitted sound to that of the original equipment Common terminology is Jake brakes after the Jacobs Company Milwaukee, Wi Section 80-69 prohibits use within city limits Portland, OR Section 1810020B3 prohibits use within 200 feet of a residence Albuquerque, NM posts signs requiring proper mufflers

Motorboatsedit

This provision is both an objective emission control and a subjective immission control Because they are moving sources, objective controls are appropriate for measurements on open waterways Many motorboats operate in bounding areas, such as small lakes or canals, with adjacent residential areas In this case, immission controls are appropriate California Section 65405, Portland OR Section 1810040, and Seattle, WA Section 2508485 require immission measurements to be made at the shoreline Many states require emission measurements to be made at 50 feet

Motor Vehicle Horns or Signaling Devicesedit

This provision is both a prohibition and an emission control it limits to use for safety warning only It limits the sound level to a specific level at a prescribed distance This provision is intended to limit horn use to safety and to limit the use of excessively loud air horns or Rumbler or Howler horns California prohibits a person operating a motor vehicle to wear a headset or earplugs on both ears Oregon Section 820370 prohibits signaling sound when an emergency vehicle is stationary or returning from an emergency

Motor Vehicles on a Public Right-of-Wayedit

This provision is an objective emission control It applies maximum sound levels to various categories of moving vehicles and for several vehicle speeds It is the backbone of vehicle sound emission regulations It generally requires a measurement of A-weighted sound level of a moving vehicle at a specific distance from the vehicle path normally 50 feet This provision has level restrictions on trucks over 10,000 GVW used locally and in interstate commerce It also covers motorcycles of two horsepower ratings, mopeds, and all other vehicles on public rights-of-way The federal government has set maximum levels for heavy trucks used in interstate commerce 40 CFR 202and for motorcycles 40 CFR 205 Most states and many cities have maximum limits and they generally agree with federal standards where they apply30 The most common speed division is 35 mph

Motor Vehicle Racing Eventsedit

This provision is an objective emission control It can define the method of vehicle operation that is used to define the maximum permitted sound level It can have a curfew Some states exempt motor vehicle racing events from noise disturbance litigation or prosecution Arizona Section 28-95503 exempts racing motorcycles from maximum sound levels and muffler requirements Illinois had detailed regulations on racing vehicles It required a 14 dB reduction in sound output, limited sound output at half mater to 115 dBA, and no more than 105 dBA at 50 feet

Motor Vehicle Sound systemsedit

This provision is both an objective emission control, a subjective emission control, and a subjective immission for vehicles on a public right-of-way The first part limits the system sound level at a fixed distance The second part uses the plainly audible definition for limiting the sound output The third part uses the noise disturbance definition to limit the impact on neighboring properties and can be applied within public transportation The most restrictive application of the plainly audible laws says that the sound cannot be audible to anyone other than the vehicle occupants There are numerous state and community restrictions on vehicle sound systems Louisiana prohibits the system from emitting sound outside of a vehicle Richmond, CA also prohibits the sound from being audible outside the vehicle Oregon prohibits sound systems being plainly audible at 50 feet California prohibits sound systems that can be heard at 50 feet Colorado Springs, CO, requires a measurement at 25 feet beyond the private property line or 25 feet from the source on public property; it does not specify a limiting level In Lakewood, CO it must not be plainly audible beyond 25 feet In Los Angeles, CA, it cannot be audible beyond 200 feet In Seattle, WA, it must not be plainly audible at 75 feet Chicago restricts levels to less than clearly audible at 75 feet Minneapolis, MN restricts levels to less than audible at 50 feet Albuquerque, NM restricts plainly audible to 25 feet, but also applies their land use limits Cincinnati, OH restricts plainly audible to 50 feet Dallas, TX prohibits sound or vibration that is detectable at 30 feet, or that violates the land use regulations Houston, TX applies land use restrictions Omaha, NE states the sound must not be audible at 100 feet Hammond, IN restricts plainly audible to 25 feet New Jersey states the sound must not be plainly audible at 50 feet between 8 am and 10 pm and not plainly audible at 25 feet between 10 pm and 8 am Florida states the sound must not be plainly audible at 25 feet, but exempts business and political systems Oregon and Tennessee state that the sound must not be plainly audible beyond 50 feet, as does Fairbanks, AK Rhode Island specifically addresses low frequency sound that can be heard 20 feet from a closed vehicle or 100 feet otherwise Salt Lake County Health Department, UT considers the sound a violation if it is plainly audible on a common carrier Austin, TX states it must not be audible at 30 feet

Motor Vehicle Theft Alarmsedit

This provision is a subjective emission control with only an operational time limit Los Angeles, CA requires silencing in 5 minutes New York City, NY Section 24221d requires automatic shut-off after 10 minutes and a prominent display of the local precinct number and telephone number Boston, MA Section 16-262 considers it a violation if the alarm is plainly audible at 200 feet and is on more than 5 minutes Other states an communities have automatic shutoff times from 10 to 15 minutes Some communities have banned such alarms

Motor Vehicle Tire Squeal and Street Drag Racingedit

This provision is a subjective immission control It is based on the noise disturbance from drag racing and tire squealing on public rights-of-way Illinois 625 ILCS 5/11-505 prohibits such activities Hammond, IN Section 6214 prohibits such activity if it creates a noise disturbance

Railroadsedit

Railroad activity is subject to federal regulations Most communities do not attempt to regulate train sound The level of train horns permitted by the Federal Railroad Administration sufficiently high that community impact occurs One method to alleviate this sound is to have a community establish a quiet zone where the rail crossings meet federal safety standards so that horn use is not needed

Recreational Off-road Vehiclesedit

This provision is both an objective emission control and a subjective immission control with a curfew It can apply to both public and private properties Since these vehicles can move in large open areas, an objective control, limiting maximum sound levels at a fixed distance, is appropriate Since they also can move in bounded areas near residences, a subjective control is appropriate Numerous states and cities have emission controls measured at 50 feet; the most common level is 82 dBA, which is similar to that for motor vehicles on public rights-of-way Colorado Springs, CO Section 98204C requires a minimum distance of 660 feet from residences Portland, OR Section 1810020C requires the area must be designated for recreational vehicle use Salt Lake health Department, UT Section 4510x requires off-highway vehicles to be at least 800 feet from a dwelling during the day and has a curfew from 10 pm to 7 am They prohibit any noise disturbance and require sound levels to the less than 96 dBA at 50 feet

Recreational Snowmobilesedit

This provision is both an objective emission control and a subjective immission control with a curfew It can apply to both public and private properties Since these vehicles can move in large open areas, an objective control, limiting maximum sound levels at a fixed distance is appropriate Since they also can move in bounded areas near residences, a subjective control is appropriate Numerous states and communities have objective controls; the most common maximum level is 78 dBA Federal law 36 CFR 218 regulates snowmobiles on federal property at 78 dBA, so states and communities are free to regulate snowmobile sound levels on their property Lincoln NE Section 824110 limits levels to 78 dBA Maine Section 13112, Chapter 937 exempts snowmobiles at sanctioned racing events Illinois 625 ILCS 40 Sec 4-4does also

Refuse Collection Vehiclesedit

This provision is an objective emission control and a subjective control It can place a maximum sound level at a specific distance for the loudest operation It can set a curfew, or it can be based on noise disturbance in residential zones Los Angeles, CA Section 11301 has a time limit that applies only within 200 feet of any residential building Chicago, IL Section 11-4-2900 considers any noise it a noise disturbance if the activity occurs between 8pm to 8am Salt Lake City, UT Section 456 considers it a noise disturbance if the activities occur between 10 pm to 7 am and closer than 800 feet from a dwelling Atlanta, GA Section 74-137a5prohibits collection between 9pm and am on a weekend day or legal holiday, except by permit In Maryland, refuse collection is exempt during daytime hours and must meet maximum land use levels 55 dBA in residential zones at night

Standing Motor Vehiclesedit

This provision is a subjective immission control It sets a time limit on engine activity It can also place a curfew on any engine activity e In Salt Lake City, UT Section 4510xi it is considered a noise disturbance if the operation lasts more than 15 minutes Dallas, TX Section 30-31 applies the code to vehicles over 14,000 GVWR; they must be more than 300 feet from a residential zone and there is a 10-minute maximum They also provide a list of idling vehicles that are exempt from prosecution such as buses or active concrete trucks Hammond, IN Section 6210 limits operation to 3 minutes in an hour for vehicles over 14,000 GVWR in either public or private property It exempts buses and taxis Massachusetts allows idling no more than 5 minutes

Building codesedit

In the case of construction of new or remodeled apartments, condominiums, hospitals and hotels, many US states and cities have stringent building codes with requirements of acoustical analysis, in order to protect building occupants from exterior noise sources and sound generated within the building itself31 With regard to exterior noise, the codes usually require measurement of the exterior acoustic environment in order to determine the performance standard required for exterior building skin design

The architect can work with the acoustical scientist to arrive at the best cost-effective means of creating a quiet interior normally 45 dB The most important elements of design of the building skin are usually: glazing glass thickness, double pane design, etc, roof material, caulking standards, chimney baffles, exterior door design, mail slots, attic ventilation ports and mounting of through the wall air conditioners A special case of building skin design arises in the case of aircraft noise, where the FAA has funded extensive work in residential retrofit

Regarding sound generated inside the building, there are two principal types of transmission First, airborne sound travels through walls or floor/ceiling assemblies and can emanate from either human activities in adjacent living spaces or from mechanical noise within the building systems Human activities might include voice, amplified sound systems or animal noise Mechanical systems are elevator systems, boilers, refrigeration or air conditioning systems, generators and trash compactors Since many of these sounds are inherently loud, the principle of regulation is to require the wall or ceiling assembly to meet certain performance standards typically Sound Transmission Class of 50, which allows considerable attenuation of the sound level reaching occupants

The second type of interior sound is called Impact Insulation Class IIC transmission This effect arises not from airborne transmission, but rather from transmission of sound through the building itself The most common perception of IIC noise is from footfall of occupants in living spaces above This type of noise is somewhat more difficult to abate, but consideration must be given to isolating the floor assembly above or hanging the lower ceiling on resilient channel Commonly a performance standard of IIC equal to 50 is specified in building codes California has generally led the US in widespread application of building code requirements for sound transmission; accordingly, the level of protection for building occupants has increased markedly in the last several decades

US occupational safety regulationsedit

The US Occupational Safety and Health Administration has established maximum noise levels for occupational exposure, beyond which mitigation measures or personal protective equipment is required32 In recent years, Buy Quiet programs and initiatives have arisen in an effort to combat occupational noise exposures These programs promote the purchase of quieter tools and equipment and encourage manufacturers to design quieter equipment33
