Audiometry is a critical diagnostic tool used to measure an individual’s hearing ability and determine the type and degree of hearing loss. It is performed by an audiologist who specializes in hearing disorders in a soundproof room. The results of audiometry tests provide crucial information for identifying and treating hearing loss, making it an essential aspect of audiology.
Types of Audiometry Tests
One of the most common types of audiometry tests is pure-tone audiometry. During this test, the individual will wear headphones and listen to a series of tones at different frequencies and volumes. The individual will indicate when they can hear the tone by raising their hand or pressing a button. The test results are plotted on an audiogram, a graph showing the individual’s hearing threshold (the quietest sound they can hear) at different frequencies. This information is crucial for identifying the type and degree of hearing loss and determining the appropriate treatment, such as hearing aids or cochlear implants.
Another type of audiometry test is speech audiometry. This test measures an individual’s ability to hear and understand speech. During this test, the individual will listen to a recorded speech at different volumes and indicate when they can understand it. The results of this test are also plotted on an audiogram. This information is crucial for identifying the type and degree of hearing loss and determining the appropriate treatment, such as assistive listening devices or speech therapy.
In addition to pure-tone and speech audiometry, other types of audiometry tests assess the functioning of the middle and inner ear. Tympanometry, for example, measures the eardrum’s movement in response to changes in air pressure, which can help determine if there is a problem with the middle ear, such as a blockage or fluid buildup. Acoustic reflex testing measures the contraction of the middle ear muscles in response to loud sounds and can help determine if there is a problem with the nerve pathways that control the middle ear muscles.
Otoacoustic emissions (OAE) testing and auditory brainstem response (ABR)
These are two other types of audiometry tests that assess the functioning of the inner ear. OAE testing measures the sounds that are naturally produced by the inner ear in response to a stimulus, which can help determine if there is a problem with the inner ear, such as damage to the hair cells. ABR testing measures the electrical activity of the inner ear and auditory nerve in response to a sound stimulus, which can help determine if there is a problem
Use of Audiometry Results
Audiometry results can also be used to determine the type and degree of hearing loss. There are different degrees of hearing loss, including mild, moderate, severe, and profound. The type of hearing loss can also be classified as sensorineural, conductive, or mixed.
The results of audiometry tests are used to determine the appropriate treatment for an individual’s hearing loss. Treatment options can include hearing aids, cochlear implants, and assistive listening devices. In some cases, surgery may be necessary to correct a problem with the outer or middle ear.
In conclusion, audiometry is a diagnostic test that measures an individual’s hearing ability. It is performed by an audiologist and typically includes pure-tone audiometry, speech audiometry, and tests that assess the functioning of the middle and inner ear. The results of audiometry tests can help diagnose a wide range of hearing disorders and determine the appropriate treatment for an individual’s hearing loss.
