Pure Tone Audiometry is a diagnostic pathology test used to evaluate a person's hearing ability by measuring their hearing threshold levels. During the test, the individual wears headphones and listens to a series of tones at varying frequencies and volumes.
They signal when they can hear each tone, allowing the audiologist to create a graph called an audiogram that shows the person's hearing thresholds.
For example, a person may be tested with tones ranging from low to high frequencies, such as 250 Hz to 8000 Hz, at different decibel levels.
The audiologist then plots the results on an audiogram, with the X-axis representing frequency and the Y-axis representing intensity in decibels.
Pure Tone Audiometry is crucial for evaluating hearing loss, monitoring changes in hearing abilities over time, and determining the type and degree of hearing impairment a person may have.
It is a non-invasive and painless procedure that provides valuable insights into an individual's hearing health.
The primary purpose of performing a Pure Tone Audiometry test is to assess an individual's hearing abilities accurately.
This test helps audiologists diagnose various types of hearing loss, such as conductive, sensorineural, or mixed hearing loss, by identifying the specific frequencies and intensity levels at which a person may have difficulty hearing.
Additionally, Pure Tone Audiometry is used to evaluate the effectiveness of hearing aids or other interventions for hearing loss.
It can also help determine if a person is a candidate for cochlear implants or other surgical procedures to improve their hearing.
Pure Tone Audiometry is essential for hearing loss screening in newborns, children, and adults, as early detection and intervention can significantly impact a person's quality of life.
It is a valuable tool for audiologists, speech-language pathologists, and other healthcare professionals involved in diagnosing and treating hearing disorders.
The cost of Pure Tone Audiometry tests in India can vary depending on various factors, such as the location of the clinic, the experience of the audiologist, and the facilities available.
On average, the cost of a Pure Tone Audiometry test in India ranges from Rs. 500 to Rs. 2000.
It is essential to consult with the healthcare provider or audiologist to inquire about the specific cost of a Pure Tone Audiometry test and any insurance coverage that may apply.
Comparing prices at different clinics can help individuals find an affordable option that meets their needs.
In Pure Tone Audiometry, the normal range refers to the typical hearing thresholds for individuals with healthy hearing. The audiogram shows different thresholds for various frequencies, measured in decibels (dB).

Pure tone audiometry uses different pitches and volumes of sound to determine the softest sounds a person can hear at different frequencies, helping to identify the type and severity of hearing loss.
The normal range for Pure Tone Audiometry indicates that an individual can hear tones at various frequencies at low decibel levels. Any thresholds above these values may suggest hearing loss or impairment in specific frequency ranges.
Pure tone audiometry testing is a safe procedure with minimal risks. The test involves listening to tones through headphones and responding when you hear them.
To prepare for a pure tone audiometry test, you don't need to do anything special. Just make sure your ears are clean and avoid exposure to loud noises before the test.
You usually don't need to remove your hearing aids or glasses during a medical test unless your doctor specifically advises you to do so.
Pure tone audiometry can help determine the type and degree of hearing loss but cannot always differentiate between temporary and permanent hearing loss. Additional tests may be needed to confirm the cause and nature of the hearing loss.
No, this test will not show if you have tinnitus. Tinnitus is typically diagnosed based on your symptoms and medical history.
Pure tone audiometry is a highly accurate test for measuring hearing loss across different frequencies.
Yes, a pure tone audiometry test can be repeated if the results are unclear to ensure an accurate assessment of your hearing ability.
Yes, this test can help detect early-stage hearing loss.
