What is an Audiometer?
An audiometer is a subjective device used to determine a person’s hearing threshold. An audiometer and special audiometric testing techniques are used by an audiologist or other trained individuals to assess the hearing threshold and to diagnose and quantify the degree of hearing loss in a person. Audiometric testing monitors one hearing. The necessary referral for medical care or possibly hearing aid fitting can be made based on these findings. Tones of various frequencies are supplied to the patient’s ear at various levels using the audiometric examination. The hearing threshold is the point at which a person can only hear the stimuli at a certain volume. Because audiometric testing equipment is subjective testing equipment, the patient must respond.
How To Read Audiometric Test Results
Wearing properly calibrated headphones and then a specially calibrated bone conductor is required for this test. You’ll be on the lookout for tones that are provided to you via audiometer. The audiologist can adjust the frequency (pitch) and strength (loudness) of tones using the audiometer. The threshold establishes which tones and intensities can be heard. Pure tones, or single-frequency sounds, are used to assess air and bone conduction and detect deficiencies. The audiogram is used to capture the air and bone conduction thresholds in the right and left ears.
The results of the hearing test are an indication for the degrees of hearing loss:
- Normal hearing: -10 to 20 dB
- Mild hearing loss: 20 to 40 dB higher than normal
- Moderate hearing loss: 40 to 70 dB higher than normal
- Severe hearing loss: 70 to 90 dB higher than normal
- Profound loss: 90 dB or more
