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.
Mixed-use areas present especially difficult conflicts that require special attention to the need to protect people from the harmful effects of noise pollution. Noise is generally one consideration in an environmental impact statement, if applicable (such as transportation system construction).
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 ...
Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage. Occupational noise is considered an occupational hazard traditionally linked to loud industries such as ship-building , mining , railroad work, welding , and construction , but can be present ...
In acoustics, noise measurement can be for the purpose of measuring environmental noise [1] or measuring noise in the workplace. Applications include monitoring of construction sites, aircraft noise, road traffic noise, entertainment venues and neighborhood noise. One of the definitions of noise covers all "unwanted sounds".

The U.S. Clean Water Act also defines municipal separate storm sewer systems and industrial stormwater discharges (such as construction sites) as point sources. [4] Man-made, natural, and groundwater reservoirs can all be contaminated by point source pollution which can threaten human health and safety. [5] Noise pollution from a jet engine [6] [7]
It prohibits construction and demolition within 500 feet of noise sensitive properties (residences included) if the equipment sound control devices are less effective than the original equipment and if noise mitigation measures are not used when the levels exceed 90 dB (weighting not specified) or more than 80 dB during the day for three days.
Light pollution – Excess artificial light in an environment; Lighting – Deliberate use of light to achieve practical or aesthetic effects; Noise pollution – Excessive displeasing noise; Quicksand – Mixture of sand, silt or clay with water, which creates a liquefied soil when agitated; Ultraviolet – Energetic, invisible radiant energy ...
