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.
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.

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 ...
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.
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.
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 ...
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
