A pure tone audiometry test measures the softest, or least audible, sound that a person can hear. During the test, you will wear earphones and hear a range of sounds directed to one ear at a time. The loudness of sound is measured in decibels (dB).

The patient is fitted with headphones and asked to push a buzzer when they hear a sound. Different pitches of sound are tested in each ear separately. The results are then plotted on a special graph called an audiogram. The final test is a speech discrimination task is also done, to assess the clarity of the hearing.

Thresholds are typically assessed at 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 3000 Hz, and 4000 Hz. Higher frequencies may be tested as indicated and possible.

Hearing loss in excess of 25 dB HL is clinically significant, as it can negatively affect communication. Some clinicians have advocated for the use of higher screening levels (i.e., 30 dB HL or 35 dB HL) when screening adults of increasing age.
