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. For example, aging typically leads to hearing thresholds which get poorer as test frequencies get higher. [10]
This type of hearing loss allows hearing at low and high frequencies, with most of the hearing loss occurring at the mid-frequencies. #5. Unilateral Hearing Loss Audiogram
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.
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.
An audiogram showing typical hearing variation from a standardized norm. Audiograms of human hearing are produced using an audiometer, which presents different frequencies to the subject, usually over calibrated headphones, at specified levels. The levels are weighted with frequency relative to a standard graph known as the minimum audibility ...
