Pure Tone Audiometry Test: Procedure, Results & Interpretation

Pure Tone Audiometry is a diagnostic pathology test used to evaluate a person's hearing ability by measuring their hearing threshold levels. During the test, the individual wears headphones and listens to a series of tones at varying frequencies and volumes.

They signal when they can hear each tone, allowing the audiologist to create a graph called an audiogram that shows the person's hearing thresholds.

For example, a person may be tested with tones ranging from low to high frequencies, such as 250 Hz to 8000 Hz, at different decibel levels.

The audiologist then plots the results on an audiogram, with the X-axis representing frequency and the Y-axis representing intensity in decibels.

Pure Tone Audiometry is crucial for evaluating hearing loss, monitoring changes in hearing abilities over time, and determining the type and degree of hearing impairment a person may have.

It is a non-invasive and painless procedure that provides valuable insights into an individual's hearing health.

What is the Purpose of Performing a Pure Tone Audiometry Test?

The primary purpose of performing a Pure Tone Audiometry test is to assess an individual's hearing abilities accurately.

This test helps audiologists diagnose various types of hearing loss, such as conductive, sensorineural, or mixed hearing loss, by identifying the specific frequencies and intensity levels at which a person may have difficulty hearing.

Additionally, Pure Tone Audiometry is used to evaluate the effectiveness of hearing aids or other interventions for hearing loss.

It can also help determine if a person is a candidate for cochlear implants or other surgical procedures to improve their hearing.

Pure Tone Audiometry is essential for hearing loss screening in newborns, children, and adults, as early detection and intervention can significantly impact a person's quality of life.

It is a valuable tool for audiologists, speech-language pathologists, and other healthcare professionals involved in diagnosing and treating hearing disorders.

Comparing prices at different clinics can help individuals find an affordable option that meets their needs.

What is the Normal Range and All Values of Pure Tone Audiometry?

In Pure Tone Audiometry, the normal range refers to the typical hearing thresholds for individuals with healthy hearing. The audiogram shows different thresholds for various frequencies, measured in decibels (dB).
