The project quickly attracted a small group of young composers and communications students, and after receiving support from the Donner Canadian Foundation it began its first project in 1972: a detailed study of the soundscape of Vancouver. The study resulted in a recording, The Vancouver Soundscape which was published in
Research suggests that noise pollution in the United States is the highest in low-income and racial minority neighborhoods, [5] and noise pollution associated with household electricity generators is an emerging environmental degradation in many developing nations.
Example of transportation noise and how it affects the community. 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 ...
Cardiovascular health: Numerous studies have linked exposure to noise pollution to heart-health effects. “We now have a pretty robust body of evidence showing that noise is related to high blood ...
Light pollution – Excess artificial light in an environment; Lighting – Deliberate use of light to achieve practical or aesthetic effects; Noise pollution – Excessive displeasing noise is mainly known as noise pollution; Quicksand – Mixture of sand, silt or clay with water, which creates a liquefied soil when agitated
The study of avoiding, reducing or using signal noise is information theory. In telephony, artificial comfort noise is used as a substitute for natural background noise, to fill in artificial silence created by discontinuous transmission systems using voice activity detection. Background noise can also affect concentration.
Noise control is a set of strategies to reduce noise pollution by reducing noise at its source, by inhibiting sound propagation using noise barriers or similar, or by the use of ear protection (earmuffs or earplugs). [20] Control at the source is the most cost-effective way of providing noise control.
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 ...
