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.
Noise pollution has been linked to metabolic syndrome, a group of health conditions including abdominal obesity and high cholesterol, triglycerides, blood sugar and blood pressure.
Recently, a tool was introduced for visual pollution measurement which can be used to measure the presence of various visual pollution objects (VPOs) and the resultant level of visual pollution. A detailed analysis of visual pollution, its context, case studies and analysis using the tool is discussed in Visual Pollution: Concepts, Practices ...
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.
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 ...
Light pollution – Excess artificial light in an environment; Lighting – Deliberate use of light to achieve practical or aesthetic effects; Noise pollution – Excessive, displeasing environmental noise; Quicksand – Mixture of sand, silt or clay with water, which creates a liquefied soil when agitated
Roadway noise and aircraft noise are the most pervasive sources of environmental noise. [2] Social activities may generate noise levels that consistently affect the health of populations residing in or occupying areas, both indoor and outdoor, near entertainment venues that feature amplified sounds and music that present significant challenges ...
Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels. Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. [2]
