Pure Tone Audiometry Test – Procedure and Interpretation

audiometry test for old age patient

Pure Tone Audiometry (PTA) is one of the most common hearing tests used to evaluate a person’s hearing ability. It measures the softest sounds that a person can hear at different frequencies.

At ExcellENT Clinic, Muvattupuzha, PTA is performed using modern audiology equipment to accurately diagnose hearing loss.

Why is Pure Tone Audiometry Done?

A PTA test helps identify:

  • Degree of hearing loss
  • Type of hearing loss
  • Hearing ability at different sound frequencies

This information is important in planning appropriate treatment such as hearing aids or medical therapy.

Procedure of Pure Tone Audiometry

During the test:

  • The patient wears headphones.
  • Sounds of different frequencies are played.
  • The patient signals when the sound is heard.
  • Responses are recorded to create an audiogram.
  • The test is painless and typically takes 15–20 minutes.

Understanding the Audiogram

An audiogram shows hearing sensitivity across frequencies.

Hearing levels are categorized as:

  • Normal hearing
  • Mild hearing loss
  • Moderate hearing loss
  • Severe hearing loss
  • Profound hearing loss
