Audiology - Results

Alternative Names

Audiometry; Hearing test; Audiography (audiogram)

Normal Values:

  • The ability to hear a whisper, normal speech, and a ticking watch is normal.
  • The ability to hear a tuning fork through air and bone is normal.
  • In detailed audiometry, hearing is normal if you can hear tones from 250 Hz - 8,000 Hz at 25 dB or lower.

What abnormal results mean:

There are many different kinds and degrees of hearing loss. In some types, you only lose the ability to hear high or low tones, or you lose only air or bone conduction. The inability to hear pure tones below 25 dB indicates some hearing loss.

The amount and type of hearing loss may give clues to the cause and outlook.

The following conditions may affect test results:
