Hearing Test Results

Your Audiogram

When your hearing is tested it is charted on what we call an audiogram. Your audiogram is a record of the softest sounds you heard during your hearing test, in each ear.

This is what an audiogram looks like.

Clean Audiogram Showing Severity Levels



Loudness is measured in decibels hearing level (dB HL).
Shown on the left side of the audiogram, loudness ranges from 0 dB HL (very soft) to 110 dB HL (very loud).

Frequency or pitch is measured in Hertz (Hz.)
Shown from left to right on the audiogram, frequency ranges from 250Hz (very low pitch) to 8000 Hz (very high pitch). Though the human ear does hear from 20-20,000Hz, we are most interested in the frequency range of speech, which falls between 250-8000Hz..
The degree of hearing loss ranges from: mild, moderate, moderately-severe, severe and profound



Normal Audiogram

Normal Hearing Audiogram




The right ear thresholds are recorded on the audiogram as a O (circle) and the left ear thresholds are represented by an X.

In this case, all thresholds fall within the normal hearing range (0 - 20 dB HL on the vertical axis).


High Frequency Hearing Loss Audiogram

High Frequency Hearing Loss Audiogram




With high-frequency hearing loss, there is milder hearing loss (or even normal hearing) for low-frequency sounds and a greater degree of hearing loss in the higher frequencies.

Typically we see this configuration of hearing loss with industrial hearing loss (noise induced hearing loss).

The aging process will also affect the ability to hear high frequency sound more than low frequency sound.



There is a wide variety in degree and configuration of hearing loss.

Our audiologists will be able to fully explain the results of YOUR hearing test and plan an appropriate and beneficial pathway of rehabilitation.
