Question 1

What is PTA in audiometry test?

Accepted Answer

PTA (Pure Tone Average) in audiometry is the average of hearing thresholds at key speech frequencies—typically 500, 1,000 and 2,000 Hz—measured in decibels (dB). It summarizes the degree of hearing loss, helps classify severity, guides diagnosis and treatment decisions, and monitors changes over time. Some clinicians include 3,000 or 4,000 Hz for specific assessments; lower PTA indicates better hearing.

Question 2

Is a PTA test painful?

Accepted Answer

A PTA (pure-tone audiometry) test is non‑invasive and generally not painful. You wear headphones or ear inserts and indicate when you hear tones; bone‑conduction testing may produce gentle vibrations but not pain. The exam is quick and safe for adults and children; you might feel minor discomfort from earpieces or a full ear canal, but there’s no lasting pain or damage.

Question 3

What is PTA 1 and PTA 2?

Accepted Answer

PTA 1 and PTA 2 are pure‑tone averages used in audiometry to summarize hearing thresholds. PTA1 is the average of thresholds at 500, 1,000 and 2,000 Hz; PTA2 averages 1,000, 2,000 and 4,000 Hz. Clinicians use these averages to grade hearing loss, guide management and monitor changes over time in clinical and occupational settings.

Question 4

What is the normal range for a PTA hearing test?

Accepted Answer

Normal pure-tone average (PTA) thresholds are generally 0–25 dB HL (hearing level) across key frequencies—often averaged at 500, 1000 and 2000 Hz. Thresholds above 25 dB indicate hearing loss (mild: 26–40 dB; moderate: 41–70 dB; severe: 71–95 dB; profound: >95 dB). Some guidelines use 0–20 dB as normal for children.

Question 5

What is the cost of a PTA test for the ears?

Accepted Answer

A pure-tone audiometry (PTA) hearing test cost varies by country and provider. On public health systems it’s often free; private clinics typically charge roughly £25–£100 in the UK, ₹300–₹1,500 in India, and about $50–$300 in the US. Prices depend on clinic type, extra tests, and whether insurance or public coverage applies—check local providers for exact fees.

Question 6

Why is the PTA test done?

Accepted Answer

The Pure Tone Audiometry (PTA) test is done to measure hearing sensitivity across frequencies, detect and quantify hearing loss, and differentiate conductive from sensorineural types. It helps diagnose causes of hearing problems, establishes a baseline, monitors changes over time or after treatment, and informs decisions about hearing aids, medical or surgical interventions, workplace fitness, and rehabilitation.
