[1] The Act established mechanisms of setting emission standards (noise regulation) for virtually every source of noise, including motor vehicles, aircraft, certain types of HVAC (heating, ventilation, and air-conditioning) equipment and major appliances.
It also put local governments on notice as to their responsibilities in land-use planning to address noise mitigation.
Congress ended funding of the federal noise control program in 1981, which curtailed development of further national regulations.
Since then, starting in 1982, the primary responsibility to addressing noise pollution shifted to state and local governments.
