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 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] Elevated workplace or environmental noise can cause hearing impairment, tinnitus, hypertension, ischemic heart disease, annoyance, and sleep disturbance.
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
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.
Given the extensive research suggesting that industrial noise exposure can cause sensorineural hearing loss, a link between hearing loss and music exposures of similar level and duration to industrial noise seems highly plausible. Determining which individuals or groups are at risk for such exposures may be a difficult task.
A cause is traumatic noise exposure that damages hair cells in the inner ear. [33] Some evidence suggests that long-term exposure to noise pollution from heavy traffic may increase the risk of developing tinnitus. [34] When there does not seem to be a connection with a disorder of the inner ear or auditory nerve, tinnitus can be called "non-otic".
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
