Hearing Test

Testing Procedure

Our hearing test will typically take about 30 mins

step 1

We will begin by asking you to fill out a questionnaire about your medical history

step 2

Our HIS will use an oto-scope and perform an a visual exam of the external ear canal and tympanic membrane

step 3

If large amount of wax are present, then it will have to be cleared first before proceeding with a hearing test

step 4

The first part of the hearing test is an automatic test to check the middle ear. This test is called impedance analysis. We will be using a small probe to measure the movements of your ear drum, and as well as the acoustic reflex

step 5

The second part of the test will be done inside a sound booth. The room is soundproof so that we can test with different sound frequencies and volume. The patient will be asked to press a button when the sound is heard. This process is called pure-tone audiometry

step 6

The last part of the test will read out a series of words that you have to repeat. This test will be carried out at different volumes to evaluate your hearing levels

Results

Types of hearing loss

After your test is done, the HIS will go over the results in detail. We will provide you with recommendations and see if further investigation is needed (ie: seeing an ENT specialist or further testing). If hearing aids are needed, our HIS will provide you with details on the type and style that is most suitable for you

Types of hearing loss

Conductive

Involves the outer or middle ear.
Usually when there is a blockage between the outer or middle ear and the inner ear. (IE: earwax or fluid).
Most common causes are ear infection, allergy or cold, hole in eardrum and earwax.
Less commonly causes include benign tumors, foreign objects and birth defects.

Sensorineural (SNHL)

Usually caused by abnormalities of the auditory nerve, cochlea or the central nervous system.
It can be caused by congenital, presbycusis, injury related or illness

Mixed

Combination of conductive and sensorineural
