  2. Absolute threshold of hearing - Wikipedia

    en.wikipedia.org/wiki/Absolute_threshold_of_hearing

    The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.

  3. Noise-induced hearing loss - Wikipedia

    en.wikipedia.org/wiki/Noise-induced_hearing_loss

    Noise levels at the Bristol Motor Speedway ranged from 96 dBA in the stands to 114 dBA for a driver inside a car during practice. Peak noise levels in the Pit area reached or exceeded 130 dB SPL, a level often associated with human hearing threshold for pain. [69]

  4. 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 ...

    Make Listening Safe is promoting the development of features in PLS to raise the users' awareness of risky listening practices. In this context, the WHO partnered with the International Telecommunication Union to develop suitable exposure limits for inclusion in the voluntary H.870 safety standards on "Guidelines for safe listening devices/systems."

    Playing video games at sound levels nearing or exceeding safe limits has been linked with hearing loss and tinnitus, according to a new study. Video gamers may be risking hearing loss or tinnitus ...

  8. Health effects from noise - Wikipedia

    en.wikipedia.org/wiki/Health_effects_from_noise

    A hearing protection device (HPD) is an ear protection device worn in or over the ears while exposed to hazardous noise to help prevent noise-induced hearing loss. HPDs reduce (not eliminate) the level of the noise entering the ear. HPDs can also protect against other effects of noise exposure such as tinnitus and hyperacusis.

  9. Pure-tone audiometry - Wikipedia

    en.wikipedia.org/wiki/Pure-tone_audiometry

    This is done by temporarily elevating the threshold of the non-test ear, by presenting a masking noise at a predetermined level. This prevents the non-test ear from detecting the test signal presented to the test ear. The threshold of the test ear is measured at the same time as presenting the masking noise to the non-test ear. Thus, thresholds ...
