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.
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.
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease. [7] [8] In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.

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 ...
In this article, I will explore what humans can hear, including frequencies, hearing in noise, directional hearing, and how it compares to an animal’s hearing ability.
Sound annoyance is a subjective matter and cannot be covered by law. In the Netherlands the government set up laws to protect households and other noise-sensitive buildings like hospitals and schools from noise pollution. There are different laws for different sound sources; airplanes, traffic, industry and neighbours. [13]
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.
This is because 20 μPa is the faintest sound the human ear can detect. [5] A pascal is a newton per square meter. The centimeter-gram-second system of units, the reference sound pressure for measuring ambient noise level is 0.0002 dyn/cm 2 , or 0.00002 N/m 2 . [ 6 ]
