Pure Tone Audiometry (PTA)

The Pure Tone Audiometry (PTA) Test is one of the most important and commonly used hearing assessments to measure a person’s hearing sensitivity across different sound frequencies. It helps determine the softest sound a person can hear in each ear, allowing specialists to identify the type, degree, and pattern of hearing loss accurately. This test is considered the gold standard for diagnosing hearing loss in adults and cooperative children.

At our audiology and hearing care center, the PTA test is performed in a sound-treated room using advanced diagnostic audiometers by experienced audiologists. The test checks both air conduction and bone conduction pathways, which helps in diagnosing conductive, sensorineural, and mixed hearing loss.

How the Pure Tone Audiometry Test Works

During the procedure, the patient wears headphones inside a soundproof room. Different tones are played at various frequencies and volumes, and the patient is asked to respond whenever the sound is heard.

The test includes:

  • Air Conduction Testing – checks the outer, middle, and inner ear pathway
  • Bone Conduction Testing – checks inner ear and auditory nerve function
  • Audiogram Recording – results are plotted on a graph for diagnosis

The test is safe, painless, non-invasive, and usually completed in 20–30 minutes.
