Audiometry test is a crucial tool to measure hearing sensitivity and identify hearing loss. It is a non-invasive, painless procedure that uses specialized equipment to produce sounds at different frequencies and volumes to evaluate a person’s ability to hear them. In this article, we will discuss the audiometry test, its types, and the normal range of hearing. We will also answer some frequently asked questions regarding the test.
Types of Audiometry Test
The two most common types of audiometry tests are pure-tone audiometry and speech audiometry. Pure-tone audiometry measures the softest sound a person can hear at different frequencies, while speech audiometry evaluates a person’s ability to hear and understand speech at different volumes.
Pure-tone Audiometry Test:
During a pure-tone audiometry test, the patient is given headphones and asked to listen to a series of tones at various frequencies and volumes. The test measures the patient’s ability to hear each tone, and the results are plotted on an audiogram. The audiogram is a graph that shows the patient’s hearing thresholds at different frequencies.
Speech Audiometry Test:
Speech audiometry tests evaluate the patient’s ability to hear and understand speech at different volumes. The test involves the use of a recorded speech sample that the patient listens to through headphones. The patient is then asked to repeat the words they hear. The results of the speech audiometry test are measured in terms of the patient’s ability to hear and understand speech at different volumes.
Normal Range of Hearing:
The normal range of hearing varies with age and gender. The following table shows the normal range of hearing for adults:
|Frequency (Hz)||Hearing Threshold (dB)|
Q: Who needs an audiometry test?
A: Anyone experiencing hearing loss, ringing in the ears, or difficulty understanding speech should consider having an audiometry test.
Q: Is an audiometry test painful?
A: No, audiometry tests are not painful. They are non-invasive and typically take about 30 minutes to complete.
Q: What should I expect during an audiometry test?
A: During the test, you will wear headphones and listen to a series of tones or speech samples. You will be asked to respond to the sounds you hear by pressing a button or raising your hand.
Q: How do I prepare for an audiometry test?
A: You should avoid exposure to loud noises for at least 24 hours before the test. You should also inform your audiologist if you are taking any medications that could affect your hearing.
