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.
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.
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 ...
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]
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 ...
[80] [81] This noise pollution significantly raises the low-frequency ambient noise levels above those caused by wind. [82] 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 following is a short list of recognized effects of noise that can be addressed as a reason for a noise ordinance. Excess non-Occupational noise exposure, hearing loss on both public and private property, speech interference on both public and private property, audio interference on both public and private property, and sleep interference on ...
