The audible frequency range for humans is typically given as being between about 20 Hz and 20,000 Hz (20 kHz), though the high frequency limit usually reduces with age. Other species have different hearing ranges. For example, some dog breeds can perceive vibrations up to 60,000 Hz. [7]
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.

Six of the top ten noisiest cities in the U.S. are located on the East coast. Louisville ranks among the top 50 loudest places in the country.
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies ...
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]
The initiative's main goal is to ensure that people of all ages can enjoy listening to music and other audio media in a manner that does not create a hearing risk. Noise-induced hearing loss , hyperacusis , and tinnitus have been associated with the frequent use at high volume of devices such as headphones , headsets , earpieces , earbuds, and ...
