The most fertile areas for roadway noise mitigation are in urban planning decisions, roadway design, noise barrier design, [14] speed control, surface pavement selection, and truck restrictions. Speed control is effective since the lowest sound emissions arise from vehicles moving smoothly at 30 to 60 kilometers per hour.
This noise regulation framework comprised a broad data base detailing the extent of noise health effects. 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 ...
Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.
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 ...
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 ...
