2. Minimum audibility curve - Wikipedia

   en.wikipedia.org/wiki/Minimum_audibility_curve

   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 ...

3. Pure-tone audiometry - Wikipedia

   en.wikipedia.org/wiki/Pure-tone_audiometry

   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.

4. Diagnosis of hearing loss - Wikipedia

   en.wikipedia.org/wiki/Diagnosis_of_hearing_loss

   The severity of a hearing loss is ranked according to ranges of nominal thresholds in which a sound must be so it can be detected by an individual. It is measured in decibels of hearing loss, or dB HL. The measurement of hearing loss in an individual is conducted over several frequencies, mostly 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz. The hearing ...

   Grade 3: Hearing loss sufficient to indicate aural rehabilitation such as hearing aids and/or speech-language services; Grade 4: Indications of cochlear implant candidacy; Brock's Hearing Loss Grades (as described in the American Academy of Audiology Ototoxicity Monitoring Guidelines from 2009): [8] Grade 0: Hearing thresholds <40 dB at all ...

   A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [ medical citation needed ] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.
