Interpreting Hearing Loss Test Results: How to Read an Audiogram

If you want to know the type and degree of hearing loss you are experiencing, you must have a complete hearing evaluation which will plotted and measured on an audiogram. This test may consist of:

1. A visual inspection of your ear and ear canal. The purpose of this test is to determine the overall health of your ear and ear canal and to discover whether any blockages, such as earwax, could be causing hearing loss. 2. A pure tone hearing test in which an audiometer will transmit a series of sounds at a variety of volumes. This test will determine the “threshold” at which you can hear various frequencies of sound.

3. A speech test during which you will listen to a series of one and two syllable words at various volumes. You will be asked to repeat the words to determine the level at which you understand speech. 4. A speech in noise test to see how well you can hear and understand speech in a noisy environment. The results of your tests will be recorded on a graph called an

audiogram which reflects your hearing loss in frequencies and decibels. Your right ear will be indicated by a red O and your left ear by a blue X. Test results showing the softest level that you hear each frequency are recorded on this graph. Hearing in the 0-20dB is the normal range; 25-40 dB is a mild loss; 45-65dB is a moderate loss, 70-90dB is severe and beyond
