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 ...
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.
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 ...
Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.
There are four defined degrees of hearing loss: mild, moderate, severe and profound. Hearing loss may be divided into four types: conductive hearing loss, sensorineural hearing loss, central auditory processing disorders, and mixed types. Hearing loss may be unilateral or bilateral, of sudden onset or progressive, and temporary or permanent.
Ménière's disease – causes sensorineural hearing loss in the low frequency range (125 Hz to 1000 Hz). ... An audiogram is the result of a hearing test.
