Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems. [1] [2] [3] Poor urban planning may give rise to noise ...
Other physical health effects. Traffic noise may also increase the risk of sleep disturbances, stroke, diabetes, and becoming overweight. [2] Noise pollution is an environmental health concern since it is often a risk factor for developing other diseases like tinnitus or impaired speech discrimination. [32]
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.
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".

It was first published on May 18, 2021. The book concerns 'noise' in human judgment and decision-making. The authors define noise in human judgment as "undesirable variability in judgments of the same problem" and focus on the statistical properties and psychological perspectives of the issue.
Sound level meters are commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental, mining and aircraft noise. [2] [3] The current international standard that specifies sound level meter functionality and performances is the IEC 61672-1:2013.
Ambient noise level is measured with a sound level meter. [4] It is usually measured in dB relative to a reference pressure of 0.00002 Pa, i.e., 20 μPa (micropascals) in SI units. [5] This is because 20 μPa is the faintest sound the human ear can detect. [5] A pascal is a newton per square meter. The centimeter-gram-second system of units ...
Noise control or noise mitigation is a set of strategies to reduce noise pollution or to reduce the impact of that noise, whether outdoors or indoors. Overview [ edit ] The main areas of noise mitigation or abatement are: transportation noise control, architectural design, urban planning through zoning codes , [1] and occupational noise control.
