Pure Tone Audiometry (PTA)

Pure Tone Audiometry (PTA) is a simple, non-invasive test that helps determine how well you hear different sounds. It is one of the most commonly used hearing assessments to check for hearing loss and its severity. Whether you’re experiencing difficulty in hearing conversations, struggling with background noise, or noticing a sudden change in hearing, PTA is the first step toward a proper diagnosis.

How Does Pure Tone Audiometry Work?

During the test, you will wear headphones and listen to a series of beeps or tones at different pitches (frequencies) and volumes. The audiologist will ask you to respond whenever you hear a sound, even if it is very faint. These results are recorded on an audiogram, a graph that helps identify the softest sounds you can hear at different frequencies.

Why is PTA Important?

PTA helps detect various types of hearing loss:

• Sensorineural hearing loss – Caused by damage to the inner ear or auditory nerve.
• Conductive hearing loss – Due to blockages or damage in the outer or middle ear.
• Mixed hearing loss – A combination of sensorineural and conductive hearing loss.

Who Needs a PTA Test?

• Individuals experiencing hearing difficulties or ringing in the ears (tinnitus).
• Those exposed to loud noises regularly (e.g., musicians, factory workers).
• People with a history of ear infections or injuries.
• Patients preparing for hearing aids or cochlear implants.
