Audiometry Testing for Hearing Loss

Audiometry is a specialized diagnostic test that provides a precise measurement of hearing ability. It evaluates how well a patient can hear different levels of loudness (intensity) and the frequency of sound wave vibrations (tone). This test is one of the most accurate ways to assess hearing loss and overall ear function.

What Does an Audiometry Test Measure?

An audiometry exam generates an audiogram, a visual chart that maps out how well each ear detects sounds across various frequencies and intensities. Each ear is tested individually using pure tones of controlled intensity. During the test, the patient may be asked to:

Raise a hand
Press a button
Indicate in another way when a sound is heard

This process helps determine the type and degree of hearing loss.

How Hearing Works

Hearing occurs when sound waves stimulate the sensory nerves of the inner ear. The signal then travels through nerve pathways to the brain, where it is processed as sound. Sound waves can reach the inner ear in two main ways:

Air conduction: through the ear canal, eardrum, and bones of the middle ear
Bone conduction: through the bones around and behind the ear

By comparing both pathways, audiometry can help identify whether hearing loss originates from the outer/middle ear (conductive hearing loss), the inner ear or auditory nerve (sensorineural hearing loss), or both (mixed hearing loss).

What to Expect During an Audiometry Exam

During the test, an audiologist may use a tuning fork or specialized equipment to measure hearing. For example:

A tuning fork may be tapped and placed in the air near the ear (air conduction) or against the mastoid bone behind the ear (bone conduction).
Earphones attached to an audiometer deliver controlled sounds, and responses are recorded to create the audiogram.

Why Audiometry Testing is Important

Audiometry is a key step in diagnosing hearing loss, tinnitus, balance issues, and other ear-related conditions. With accurate results, our audiologists can recommend tailored treatment options, which may include:

Hearing aids
Medical or surgical treatments
Lifestyle adjustments for better communication and quality of life
