Pure tone audiometry is a test of hearing that uses pure tones, or single frequencies of sound, to measure the softest sounds that a person can hear.
How do you perform pure tone audiometry?
Pure tone audiometry is performed in a soundproof booth. The audiologist will present a series of pure tones at different frequencies and intensities to each ear. The person being tested will use a button or raise their hand to indicate when they hear the sound.
What is the purpose of the pure tone test?
The purpose of the pure tone test is to determine the softest sounds that a person can hear at different frequencies. This information can be used to diagnose hearing loss and to determine the type and severity of the hearing loss.
What is the normal range for pure tone audiometry?
The normal range for pure tone audiometry varies depending on the frequency of the sound. For example, the normal threshold for a 1000 Hz tone is 20 dB HL (hearing level). This means that a person with normal hearing should be able to hear a 1000 Hz tone at a level of 20 dB HL.
What are the benefits of pure tone audiometry?
Pure tone audiometry is a valuable tool for diagnosing hearing loss and determining the type and severity of the hearing loss. It is also a good way to track the progression of hearing loss over time.
What are the risks of pure tone audiometry?
There are no known risks associated with pure tone audiometry. However, some people may find the test to be uncomfortable, especially if they have severe hearing loss.
If you are concerned about your hearing, it is important to see an audiologist. They can perform a pure tone audiometry test and recommend treatment options if necessary.
