Hearing tests measure how much sound we hear. There are many different types of tests and a clinic or health professional will carry out the best tests to assess you or your child’s hearing. The results of hearing tests can be shown on a chart called an audiogram. Measuring your hearing helps to find the type of hearing problem you or your child might have and help your health professional suggest the best treatment options.
Hearing loss is measured in decibles hearing level (or dBHL). This number represents the softest level you or your child can hear. Hearing level can be measured for pure tone sounds, as well as for speech sounds, and can be reported for both ears (bilateral) or for each ear individually (unilateral). The amount of hearing loss someone has is ranked as mild, moderate, severe, or profound.
You can hear quiet sounds down to 20 dBHL.
