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.
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 ...
It also put local governments on notice as to their responsibilities in land-use planning to address noise mitigation. 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 ...
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.
HSE inspector Matthew Lea said "The Control of Noise at Work Regulations require employers to put measures in place to ensure that their employees can work safely, without putting their hearing at risk." [8] Speaking on the dangers of exposure to noise he said "Noise-induced hearing loss is a degenerative condition and the ear cannot repair ...

Environmental mitigation refers to the process by which measures to avoid, minimise, or compensate for adverse impacts on the environment are applied. [1] In the context of planning processes like Environmental Impact Assessments, this process is often guided by applying conceptual frameworks like the "mitigation hierarchy" or "mitigation sequence". [2]
Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities. [1] Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity.
