The red line shows the level of hearing of a person’s right ear. The left ear is plotted with a blue line. The area below the line shows the levels of hearing loss that this person can hear and the area above the line shows the levels that the person can’t hear.
To find out your level of hearing, a hearing professional
will play a series of beeps
and ask you to raise your hand or press a button when you can hear them. The professional will usually start with a level you can hear and then turn down the volume each time until you can’t hear it. The professional will then repeat this with sounds of lower or higher frequencies.
This test shows your hearing “threshold” or the point where you can’t hear any more. This threshold is plotted for both your ears as two separate lines on your audiogram.Your audiogram can tell you a lot about your hearing
, including the frequencies you can hear and the volume you can hear them at. This is important to know because each sound you hear has a certain frequency. Birdsong has a higher frequency while tubas have a lower frequency.Here are some common sounds plotted on a standard audiogram:
