Audiometry (PTA)

Audiometry PTA is a common way to check how well you hear. It tests the outer, middle, and inner ear functions to find hearing problems. Early detection helps doctors recommend hearing aids, implants, or treatments.

During the audiometry procedure, you wear headphones in a quiet room. When you hear a beep or tone, you raise your hand or press a button. The quietest sounds you hear at certain pitches are marked on an audiogram.

Before the test, avoid loud noises for at least 16 hours to prevent temporary hearing changes. Ensure your ears are clean and free from excessive wax. The procedure typically takes less time and is painless.

Interpretation of audiometry results requires consultation with an audiologist or ENT specialist. Do not self-diagnose or self-medicate based on test results.

Disclaimer: Audiometry testing is available at the nearest Tata 1mg-partnered audiology lab.

How to Prepare for the Audiometry (PTA)?

• Avoid exposure to loud noise for at least 16 hours before the test.
• Keep your ears clean and free from wax buildup before the test.
• Inform your healthcare provider about any ear pain, infections, or hearing issues.
• Remove hearing aids or earplugs before the test.
• Bring existing hearing test reports if available.

How is the Audiometry (PTA) Performed?

• The patient sits comfortably in a soundproof booth.
• Headphones or earphones are placed over or inside the ears.
• Pure tones are played at different frequencies and volumes to each ear separately.
• The patient signals when a tone is heard by raising a hand or pressing a button.
• Testing typically starts at 1000 Hz, progressing to 8000 Hz, then back down to cover the audiometric range.

How Does Audiometry Work?

The test measures the softest sound level that the patient can hear at various frequencies. These thresholds are plotted on an audiogram to represent hearing sensitivity across pitches visually.

Who Should Avoid or Take Precautions During the Audiometry (PTA)?

• Patients with active ear infections or perforated eardrums should inform the clinician.
• Children may require behavioral adaptations or parental presence for cooperation.
• Patients with cognitive impairments may need test modifications.

What to Expect During the Audiometry (PTA)?

• A series of beeps or tones at different pitches and volumes.
• Instructions to respond whenever you hear a tone, even faintly.
• Each ear is tested individually.

What to Expect After the Audiometry (PTA)?

• No side effects; normal activities can be resumed immediately.
• If hearing loss is detected, further evaluation or treatment options may be discussed.

Is the Audiometry (PTA) Safe?

Yes, the Audiometry (PTA) is completely safe. It is a non-invasive test that measures how well you hear different sounds, tones, and speech levels. No radiation, needles, or medications are involved, and there are no known side effects.

Is it Safe to have the Audiometry (PTA) if you are Pregnant?

Yes, Audiometry (PTA) is safe during pregnancy. It is a non-invasive test that involves listening to sounds at different frequencies and volumes to assess hearing ability.

What are the Risks and Limitations of the Audiometry (PTA)?

• Audiometry is safe and non-invasive.
• Results may be affected by ambient noise or patient cooperation.
• May not detect all types of hearing disorders (e.g., auditory neuropathy).

How Are Audiometry Test Results Used?

• To diagnose the type and degree of hearing loss.
• Guide treatment decisions, including whether to use hearing aids or make medical referrals.
• Monitor progression of hearing loss over time.
