Industrial noise control is a subset of interior architectural control of noise, with emphasis on specific methods of sound isolation from industrial machinery and for protection of workers at their task stations. Sound masking is the active addition of noise to reduce the annoyance of certain sounds, the opposite of soundproofing.
A noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution. Noise barriers are the most effective method of mitigating roadway, railway, and industrial noise sources – other than cessation of ...
The system of Pollution Prevention and Control is replacing that of IPC and has been taking effect between 2000 and 2007. The Pollution Prevention and Control regime implements the European Directive (EC/96/61) on integrated pollution prevention and control.
Awaaz Foundation is a non-governmental organization in India working to control noise pollution from various sources through advocacy, public interest litigation, awareness, and educational campaigns since 2003. [106] Despite increased enforcement and stringency of laws now being practiced in urban areas, rural areas are still affected. [107]
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
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. [2] The Environmental Protection Agency (EPA) retains authority to conduct research and ...
The EPA coordinated all federal noise control activities through its Office of Noise Abatement and Control. The EPA phased out the office's funding in 1982 as part of a shift in federal noise control policy to transfer the primary responsibility of regulating noise to state and local governments. However, the Noise Control Act of 1972 and the ...
Sound baffles on the wall of a recording studio. A sound baffle is a construction or device which reduces the strength (level) of airborne sound.Sound baffles are a fundamental tool of noise mitigation, the practice of minimizing noise pollution or reverberation.
