  2. Hearing range - Wikipedia

    en.wikipedia.org/wiki/Hearing_range

    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 ...

  3. Noise pollution - Wikipedia

    en.wikipedia.org/wiki/Noise_pollution

    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.

    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.

  5. Audio frequency - Wikipedia

    en.wikipedia.org/wiki/Audio_frequency

    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]

  6. Health effects from noise - Wikipedia

    en.wikipedia.org/wiki/Health_effects_from_noise

    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.

  7. Aircraft noise pollution - Wikipedia

    en.wikipedia.org/wiki/Aircraft_noise_pollution

    Noise-generating aircraft propeller. Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during takeoff, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.

  8. Infrasound - Wikipedia

    en.wikipedia.org/wiki/Infrasound

    The U.S. space program, worried about the harmful effects of rocket flight on astronauts, ordered vibration tests that used cockpit seats mounted on vibration tables to transfer "brown note" and other frequencies directly to the human subjects. Very high power levels of 160 dB were achieved at frequencies of 2–3 Hz.

  9. Environmental noise - Wikipedia

    en.wikipedia.org/wiki/Environmental_noise

    Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities. [1] Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity.
