Audiometry – Definition & Detailed Explanation – Audio Terms Glossary

I. What is Audiometry?

Audiometry is a branch of audiology that focuses on the measurement of hearing ability. It involves a series of tests that are used to evaluate an individual’s hearing sensitivity and identify any potential hearing loss. These tests are typically conducted by audiologists in a soundproof booth using specialized equipment.

II. What is an Audiogram?

An audiogram is a graph that displays the results of an individual’s hearing test. It shows the softest sounds that a person can hear at different frequencies, typically ranging from low to high pitches. The audiogram is an essential tool for audiologists to assess the type and degree of hearing loss a person may have.

III. What is Pure-Tone Audiometry?

Pure-tone audiometry is a common type of hearing test that measures an individual’s hearing sensitivity to pure tones at various frequencies. During the test, the individual wears headphones and is asked to respond when they hear a sound. The audiologist will then plot the results on an audiogram to determine the person’s hearing thresholds.

IV. What is Speech Audiometry?

Speech audiometry is a type of hearing test that evaluates an individual’s ability to hear and understand speech. The test typically involves the presentation of recorded speech stimuli at different volumes to assess the person’s speech recognition abilities. Speech audiometry is often used in conjunction with pure-tone audiometry to provide a comprehensive assessment of an individual’s hearing abilities.

V. What is Tympanometry?

Tympanometry is a test that evaluates the function of the middle ear and the mobility of the eardrum. During the test, a probe is placed in the ear canal and changes in air pressure are introduced to measure the movement of the eardrum. Tympanometry can help identify conditions such as fluid in the middle ear, eardrum perforations, or issues with the Eustachian tube.

VI. What is Otoacoustic Emissions (OAE) Testing?

Otoacoustic emissions (OAE) testing is a non-invasive test that measures the sounds produced by the inner ear in response to external stimuli. During the test, a small probe is placed in the ear canal and sounds are presented to elicit a response from the cochlea. OAE testing is often used to screen for hearing loss in newborns and young children, as well as to monitor the function of the cochlea in individuals of all ages.
