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.
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 ...
Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.
What you can do to limit your exposure to noise pollution. All three experts agree that noise pollution is a problem best addressed at the societal level rather than being up to individuals.
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.
Background noise is an important concept in setting noise levels. Background noises include environmental noises such as water waves , traffic noise , alarms , extraneous speech , bioacoustic noise from animals, and electrical noise from devices such as refrigerators , air conditioning , power supplies , and motors .
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 Free America is a national, non-profit organization aimed at reducing noise pollution in the community. The organization's main target is noise from boom cars (vehicles with loud sound systems), leaf blowers, motorcycles, and car alarms. [1] Noise Free America has a 501(c)(3) non-profit status and has chapters in 27 states across the U.S ...
