To measure your level of hearing, one of our audiometric officers will conduct an audiometric test, or hearing test, that will produce an audiogram.

The hearing test process

  1. Firstly, you will be shown into the soundproof audio both and asked to put on a set of head phones.
  2. The audiometric officer will then show you how to use 2 different buttons to respond when you hear a series of tones in your ears.
  3. The hearing test starts on one frequency at a volume you can hear.
  4. The volume (measured in decibels) is then decreased until you can no longer hear it, identifying your threshold.
  5. This brief process is repeated for both ears on 8 frequencies, usually taking about 5 minutes.
  6. The thresholds are plotted for both of your ears as two separate lines on your  

hearing test PerthWhat is an audiogram?

An audiogram, or hearing test graph, is provided to you at the end of an audiometric or hearing test.

An audiogram is a graph which gives a detailed description of your personal hearing ability. On the audiogram, usually red with round circles indicates your right ear thresholds and blue with crosses represents your left ear.

The audiogram illustrates your hearing ability by showing your hearing threshold at various frequencies. Hearing threshold is an indication of how soft a sound may get before it is inaudible. A hearing threshold of between 0 and 25 dB is considered normal.
