Annoyance effects of noise are minimally affected by demographics, but fear of the noise source and sensitivity to noise both strongly affect the 'annoyance' of a noise. [42] Sound levels as low as 40 dB(A) can generate noise complaints [ 43 ] and the lower threshold for noise producing sleep disturbance is 45 dB(A) or lower.
This industrial symphony may just seem like background din, considering that an estimated 1 in 3 Americans is exposed to “excessive noise levels,” but it can have very real health consequences ...
Effects of excessive noise pollution include hearing impairment, speech intelligibility, sleep disturbance, physiological functions, mental illness, and performance. The World Health Organization recommends creating a "National Plan for a Sustainable Noise Indoor Environment" specific to each country.
Highway noise is today less affected by motor type, since the effects in higher speed are aerodynamic and tire noise related. Other contributions to the reduction of noise at the source are: improved tire tread designs for trucks in the 1970s, better shielding of diesel stacks in the 1980s, and local vehicle regulation of unmuffled vehicles.
Loud noise exceeding levels that can damage hearing is regularly encountered by commuters using buses, subways and even biking, a Canadian study suggests. Commuters often exposed to damaging noise ...
Noise presents a fairly common workplace hazard: occupational hearing loss is the most common work-related injury in the United States, with 22 million workers exposed to hazardous noise levels at work and an estimated $242 million spent annually on worker's compensation for hearing loss disability.

[79] [80] This noise pollution significantly raises the low-frequency ambient noise levels above those caused by wind. [81] Animals such as whales that depend on sound for communication can be affected by this noise in various ways. Higher ambient noise levels also cause animals to vocalize more loudly, which is called the Lombard effect ...
The Texas penal code specifies that “a noise is presumed to be unreasonable if the noise exceeds a decibel level of 85 after the person making the noise receives notice from a magistrate or ...
