Hearing Test

THE HEARING TEST

It is impossible to choose the correct hearing aid without first having your hearing assessed. A full diagnostic evaluation of your hearing will normally consist of the following:

  • Otoscopic Examination:  – to evaluate the status of the outer ear canal

otoscopy

  • Tympanometry – to evaluate the function of the middle ear

tympanometry

  • Pure tone Air and Bone Audiometry – where you will hear beep sounds at different pitches (frequencies) to evaluate how well you hear. This test takes place in a sound proof booth

hearing test

  • Speech discrimination test – to determine how much the hearing loss is affecting your ability to understand speech

The diagnostic test battery can thus determine whether you need a hearing aid, or if the cause of the hearing loss can be treated with medication or by surgery

The result of the hearing test is plotted on a graph called an audiogram.

THE AUDIOGRAM

An audiogram is a graphic representation of yourhearing ability. During the test you will hear different pitches. These results are plotted on a graph.

The horizontal line at the bottom of the graph represents the different pitches. The low tones (like the engine of a car) on the left side and the high pitches (like a bird singing) on the right side.
