Federal Noise Law

Despite efforts by noise denialists to try to dismiss excessive noise as a “new” issue prompted by COVID, gentrification, or whatever recent trends they can ascribe it to, noise regulations have existed all over the world (including the U.S.) for hundreds of years.

At the federal level, the first environmental laws and public health policies to reduce ambient (background) noise levels were enacted more than 50 years ago. The landmark U.S. ecology legislation of the early 1970s — starting with the Clean Air Act, one the first national environmental laws anywhere in the world — recognized the need to regulate a wide range of unhealthy air pollution that was rampant at the time, including excessive noise.

Collectively, these laws enabled the U.S. to reduce historic levels of air and water pollution, particularly in urban areas. The noise-pollution regulations in the Clean Air Act were followed by the 1972 Noise Control Act and 1978 Quiet Communities Act, demonstrating that noise was an ongoing health and environmental concern.

But more than 40 years before the second Trump administration‘s autocratic evisceration of critical social programs, the first Reagan administration similarly de-funded the EPA’s noise-reduction efforts in the early 1980s — specifically, the agency’s Office of Noise Abatement and Control — and Americans have been paying the price with their health ever since.

But delegating noise-abatement policy and enforcement to state governments does not legally absolve the EPA of its responsibility to implement federal noise regulations. Although it may not do so directly, it must ensure that state authorities do — and in this regard has utterly abdicated that mandated role. Once it off-loaded enforcement onto the states, it stopped monitoring the outcome.¹

1970 Clean Air Act

Under the Clean Air Act, which regulates all forms of air pollution in the U.S., the Environmental Protection Agency (EPA) was mandated to investigate and study noise and its effects on public health and welfare, coordinate federal noise-control activities, disseminate information to the public regarding noise pollution and its adverse health effects, and evaluate the effectiveness of existing noise-related regulations for protecting the public health and welfare.

Title IV of the Act — designated as the Noise Pollution and Abatement Act of 1970 — established the EPA‘s Office of Noise Abatement and Control (ONAC) to, among other things:

• Determine the “projected growth of noise levels in urban areas through the year 2000” and “effects of sporadic extreme noise … as compared with constant noise”
• Reduce noise pollution in urban areas
• Minimize noise-related impacts and physiological and psychological effects on humans, and effects on wildlife and property (including property values)
• Other noise-related issues

In 1974, the ONAC published a ‘Model Community Noise Ordinance’ that local governments could modify and adopt as needed. The Reagan administration prompted Congress to eliminate the ONAC’s funding in 1981, but the EPA still retains all of its statutory authority to regulate noise under the Clean Air Act. A bill to restore the ONAC’s funding has been pending in Congress since 2021.

Motor vehicles

Among the sources of pollution that the Clean Air Act authorizes the EPA to regulate are emissions from automobiles, prohibiting “any person to manufacture or sell, or offer to sell, or install, any part or component intended for use with, or as part of, any motor vehicle or motor vehicle engine, where a principal effect of the part or component is to bypass, defeat, or render inoperative any [emissions control] device,” which refers to mufflers.

In other words, it is illegal under federal law to tamper with or replace the original muffler that came with the car in a way that prevents the exhaust system from effectively controlling emissions — including noise. This encompasses the sensors and software comprising the onboard diagnostics systems (which must be altered to “re-tune” the engine). [See Clean Air Act § 203(a)(3)(A), 42 U.S.C. § 7522(a)(3)(A)]

The Clean Air Act (CAA) also prohibits manufacturing, selling, offering to sell, or installing parts or components designed to bypass, defeat, or render inoperative any device installed to comply with CAA regulations, when the person doing so knows or should know it will have that effect [see CAA § 203(a)(3)(B), 42 U.S.C. § 7522(a)(3)(B)]. Civil fines for selling or installing emission-control defeat devices can be over $5,000 per device, and dealers can be fined over $5,000 per tampered vehicle.

Similar provisions have been incorporated into state laws — including Rhode Island’s — but both federal and state motor-vehicle pollution laws are inconsistently and sporadically enforced.

1972 Noise Control Act

The Noise Control Act expanded on the Clean Air Act by establishing “a national policy to promote an environment for all Americans free from noise that jeopardizes their health and welfare,” and providing specific authority for federal noise abatement and control. (42 U.S.C. 4901 et seq.)

Motor vehicles

Under the authority of the Noise Control Act, the 1982 Code of Federal Regulations (CFR) established rules for exhaust-systems in both highway and off-road motorcycles built from 1983 on. They require all motorcycles to be equipped with EPA-approved mufflers not just when they leave the factory, but at all times while they are in the U.S., and as of 1986 no louder than 80 decibels.

Further, it is a violation of federal law to tamper with motorcycle emission-control devices, including those that control noise emissions (i.e., mufflers):

The EPA’s Vehicle and Engine Enforcement branch is part of its Air Enforcement division, but by the agency’s own admission devotes minimal resources to enforcing federal noise regulations.

1978 Quiet Communities Act (QCA)

The QCA amended the 1972 Noise Control Act to establish a nation-wide Quiet Communities Program, which included grants to states, local governments, and regional planning agencies for:

• Identifying and determining the nature and extent of noise problems
• Planning, developing, and establishing noise-control capacity (including initial equipment)
• Developing abatement plans for areas around major stationary sources of noise, including transportation facilities such as airports, highways, and railyards
• Evaluating techniques for controlling noise and demonstrating the best available techniques in such jurisdictions

The Quiet Communities Act also supported studies and demonstrations to determine the resources and personnel that state and local governments would need to establish and implement effective noise abatement and control programs, and the development of educational and training materials and programs, such as national and regional workshops, to support state and local noise abatement and control programs. (42 U.S.C. 4901; Public Law 95–609; 92 Stat. 3079)

Other federal laws and legal rulings

1989 Supreme Court ruling on NY City noise-control regulations for concerts in Central Park

Writing for the 6–3 majority, Justice Anthony Kennedy said that in cases in which the content of people’s expression itself is not being banned but simply being regulated as to “time, place, and manner,” the Constitution does not require the government to choose the “least-restrictive means available” to do so. In other words, regulating sound levels is not an infringement on free-speech rights. And as with all other Supreme Court rulings, this applies nation-wide. Noise is not a right.

The Quiet Communities Act of 2021+

A U.S. House of Representatives bill (H.R. 4892) to restore funding for the EPA’s Office of Noise Abatement and Control, which was de-funded by the Reagan administration in the early 1980s. It was first introduced in July 2021 by Rep. Grace Meng (D–NY), representing the 6th Congressional district, a “majority minority” area of Queens. It was referred to the House Subcommittee on Environment and Climate Change, and re-introduced in 2023 and 2025.

Among the 2021 bill’s co-sponsors were liberal U.S. Reps. Ruben Gallego (D–AZ), Kaialiʻi Kahele (D–HI), Ted Lieu (D–CA), Joe Neguse (D–CO), Eleanor Holmes Norton (D–DC), Karen Bass (D–CA) who later became mayor of Los Angeles, and progressives Judy Chu (D–CA), Yvette Clarke (D–NY), Adriano Espaillat (D–NY), Raul Grijalva (D–AZ), Pramila Jayapal (D–WA), Mondaire Jones (D–NY), Barbara Lee (D–CA), Gwen Moore (D–WI), Rashida Tlaib (D–MI), Nydia Velasquez (D–NY), and Frederica Wilson (D–FL).
