Pure-tone audiometry (audiogram) | MedLink Neurology
https://www.medlink.com/articles/pure-tone-audiometry-audiogram
The purpose of pure-tone audiometry is to assess auditory acuity for each ear as a function of sound frequency and as a function of whether sound is conducted by air or bone. Such information provides essential information on the underlying causes of hearing impairment and is important in selecting therapeutic interventions, including hearing aids or cochlear implants, …

Pure tone: A single frequency sound. 2. Audiometer: Equipment used to generate pure tones of varying frequency and loudness and control their presentation. 3. Air conduction (AC) threshold: lowest level dB HL (hearing threshold) at which the subject perceives 50% of pure tones introduced via earphones or speakers.
Perspectives on the Pure-Tone Audiogram

Results: The pure-tone audiogram provides information as to hearing sensitivity across a selected frequency range. Normal or near-normal pure-tone thresholds sometimes are observed despite cochlear damage. There are a surprising number of patients with acoustic neuromas who have essentially normal pure-tone thresholds.

Pure-tone audiometry. Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125 kHz to 8 kHz with the use of headphones.

This little demo is not too unlike the standard audiometric test known as a pure-tone audiogram. We present pure tones of different frequencies at different sound levels, and adjust their level until they become inaudible in order to measure the "threshold".

Pure-tone audiometry involves measuring the peripheral and central auditory systems. Audiometry tests can detect whether you have sensorineural hearing loss (damage to the nerve or cochlea) or conductive hearing loss (damage to the eardrum or the tiny ossicle bones). During an audiometry evaluation, a variety of tests may be performed.

Audiograms typically test frequencies between 250Hz and 8000Hz. Human speech usually falls between 250Hz and 6000Hz. AUDIOMETRIC TESTING: During testing, the audiometer delivers various “pure tone” sounds at particular frequencies and intensities, from low to high.
