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.
The 'Audiometric Classifications of Hearing Impairment' according to the International Bureau Audiophonology (BIAP) in Belgium is as follows: [5] Normal or subnormal hearing: average tone loss is equal or below 20 dB HL; Mild hearing loss: average tone loss between 21 and 40 dB HL; Moderate hearing loss
WHO's initial classification for the effects of diseases, the International Classification of Impairments, Disabilities, and Handicaps (ICIDH), was created in 1980. [ 2 ] The ICF classification complements WHO's International Classification of Diseases -10th Revision (ICD), which contains information on diagnosis and health condition, but not ...
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
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 ...

Over-the-counter (OTC) hearing aids are amplification devices that consumers who suffer from mild to moderate hearing loss can buy directly without a prescription, says Melissa Schnitzspahn, AuD ...
Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss.
