2. Sensorineural hearing loss - Wikipedia

   en.wikipedia.org/wiki/Sensorineural_hearing_loss

   An audiogram is the result of a hearing test. The most common type of hearing test is pure tone audiometry (PTA). It charts the thresholds of hearing sensitivity at a selection of standard frequencies between 250 and 8000 Hz. There is also high frequency pure tone audiometry which tests frequencies from 8000 to 20,000 Hz.

   There is also high frequency Pure Tone Audiometry covering the frequency range above 8000 Hz to 16,000 Hz. Threshold equalizing noise (TEN) test; Masking level difference (MLD) test; Psychoacoustic (or psychophysical) tuning curve test; Speech audiometry is a diagnostic hearing test designed to test word or speech recognition. It has become a ...

4. Pure-tone audiometry - Wikipedia

   en.wikipedia.org/wiki/Pure-tone_audiometry

   Pure-tone audiometry is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss [ 1 ][ 2 ] and thus providing a basis for diagnosis and management. Pure-tone audiometry is a subjective, behavioural measurement of a hearing threshold, as it ...

5. Noise-induced hearing loss - Wikipedia

   en.wikipedia.org/wiki/Noise-induced_hearing_loss

   Otorhinolaryngology, audiology. Noise-induced hearing loss (NIHL) is a hearing impairment resulting from exposure to loud sound. People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears. [ 1 ] When exposure to hazards such as noise occur at work ...

6. Presbycusis - Wikipedia

   en.wikipedia.org/wiki/Presbycusis

   Presbycusis (also spelled presbyacusis, from Greek πρέσβυς presbys "old" + ἄκουσις akousis "hearing" [ 1 ]), or age-related hearing loss, is the cumulative effect of aging on hearing. It is a progressive and irreversible bilateral symmetrical age-related sensorineural hearing loss resulting from degeneration of the cochlea or ...

7. Diagnosis of hearing loss - Wikipedia

   en.wikipedia.org/wiki/Diagnosis_of_hearing_loss

   Hearing loss is generally measured by playing generated or recorded sounds, and determining whether the person can hear them. Hearing sensitivity varies according to the frequency of sounds. To take this into account, hearing sensitivity can be measured for a range of frequencies and plotted on an audiogram. Other method for quantifying hearing ...
