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]
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.
These factors may diminish well-being of people that suffer from sound annoyance. Other factors that correlate with sound annoyance are increased absence form work, [3] sleep disturbance, [3] and interference with performing cognitive tasks like paying attention at school.

The ocean has become a raucous cacophony as the noise from human activity has grown louder and more prevalent, according to a study. The noisy ocean: Humans have made the world's seas a very loud ...
The report "A Review of Published Research on Low Frequency Noise and its Effects" [54] contains a long list of research about exposure to high-level infrasound among humans and animals. For instance, in 1972, Borredon exposed 42 young men to tones at 7.5 Hz at 130 dB for 50 minutes.
Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity. The effects in humans of exposure to environmental noise may vary from emotional to physiological and psychological. [2] Noise at low levels is not necessarily harmful.
The risk of negative health effects from sound exposures (be it noise or music) is primarily determined by the intensity of the sound , duration of the event, and frequency of that exposure. [9] These three factors characterize the overall sound energy level that reaches a person's ears and can be used to calculate a noise dose.
Research has traditionally focused mostly on the negative effects of sound on human beings, as in exposure to environmental noise. Noise has been shown to correlate with health-related problems like stress, reduced sleep and cardiovascular disease. [ 23 ]
