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 ...
This is not the best threshold found for all subjects, under ideal test conditions, which is represented by around 0 phon or the threshold of hearing on the equal-loudness contours, but is standardised in an ANSI standard to a level somewhat higher at 1 kHz . There are several definitions of the minimal audibility curve, defined in different ...
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.
In adults, normal hearing is typically defined as thresholds of 25 dB HL or better (lower). [9] Thresholds of 30 dB HL and above indicate hearing loss. The configuration of thresholds on an audiogram can often help determine the cause(s) of the hearing loss.
Here’s a startling statistic: about 15 percent (38 million) of American adults have some level of hearing loss. From there, men are almost twice as likely as women to have trouble hearing, ...
