t. e. 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 ...
The main areas of noise mitigation or abatement are: transportation noise control, architectural design, urban planning through zoning codes, [1] and occupational noise control. Roadway noise and aircraft noise are the most pervasive sources of environmental noise. [2] Social activities may generate noise levels that consistently affect the ...
Acoustics is defined by ANSI/ASA S1.1-2013 as " (a) Science of sound, including its production, transmission, and effects, including biological and psychological effects. (b) Those qualities of a room that, together, determine its character with respect to auditory effects." The study of acoustics revolves around the generation, propagation and ...
Landslide mitigation refers to several human-made activities on slopes with the goal of lessening the effect of landslides. Landslides can be triggered by many, sometimes concomitant causes. In addition to shallow erosion or reduction of shear strength caused by seasonal rainfall, landslides may be triggered by anthropic activities, such as ...
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".

Environmental issues in Pakistan include air pollution, water pollution, noise pollution, climate change, pesticide misuse, soil erosion, natural disasters, desertification and flooding. According to the 2020 edition of the environmental performance index (EPI) ranking released by Yale Center for Environmental Law & Policy, Pakistan ranks 142 ...
Noise regulation includes statutes or guidelines relating to sound transmission established by national, state or provincial and municipal levels of government. After the watershed passage of the United States Noise Control Act of 1972, [1] other local and state governments passed further regulations. A noise regulation [citation needed ...
Noise-generating aircraft propeller. Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during takeoff, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.
