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. Minimum audibility curve - Wikipedia

   en.wikipedia.org/wiki/Minimum_audibility_curve

   Minimum audibility curve is a standardized graph of the threshold of hearing frequency for an average human, and is used as the reference level when measuring hearing loss with an audiometer as shown on an audiogram.

4. Audiogram - Wikipedia

   en.wikipedia.org/wiki/Audiogram

   Audiograms are unable to measure hidden hearing loss, [15] [16] which is the inability to distinguish between sounds in loud environments such as restaurants. Hidden hearing loss is caused by synaptopathy in the cochlea, [17] as opposed to sensorineural hearing loss caused by hair cell dysfunction. Audiograms are designed to "estimate the ...

5. Absolute threshold of hearing - Wikipedia

   en.wikipedia.org/wiki/Absolute_threshold_of_hearing

   The hearing of older adults is shown to be significantly less sensitive than that of younger adults at frequencies of 4000 and 8000 Hz, corresponding approximately to the piano keys and tones of b′′′′ (B7) and b′′′′′ (B8), respectively. B8 is near the high end of the piano frequency range.

   There are a range of treatment options for sensorineural hearing loss. One of the most common is hearing aids. Traditionally, a hearing aid is a medical device that is fit to a person’s hearing ...

7. Pure-tone audiometry - Wikipedia

   en.wikipedia.org/wiki/Pure-tone_audiometry

   The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause.
