Hearing Test

In order to determine the cause of your hearing loss, and thereby the possibilities of improving your hearing we will first take a full history of your perceived issues followed by a thorough Audiological hearing examination.

A hearing test is performed which examines the quietest sound that you are able to hear at different frequencies as well as testing your ability to understand speech. The hearing test takes about an hour to complete and is completely painless.

Otoscopy
Video Otoscopy is an examination of the ear canal and eardrum. You will be able follow along on the screen during the examination. The study assesses your ear canal and eardrum for general signs of disease (such as irritation, swelling, or perforation of the eardrum).

Pure Tone Audiometry
Pure Tone Audiometry tests your ability to hear sound waves that are presented through the air and the bone pathways respectively. We record your hearing threshold for each frequency, ie. We record the quietest sound you are able to hear ranging from high pitch to low pitch sounds.

Speech Audiometry
Speech audiometry investigates your speech perception skills. This test is not related to intelligence; rather it indicates how clearly your auditory system can understand speech and distinguish words. For each ear the discriminating score is calculated as a percentage score.

Impedance
Impedance testing examines the eardrums flexibility and the middle ear’s ability to equalize as well as testing the nerve function of the auditory nerves. This is used to more accurately determine the type or category of hearing loss.

Review of Test Results
Following the above test the results will be thoroughly reviewed with you. The result of the audiometric testing will be displayed on an audiogram which is a diagram showing your hearing threshold for each tone (frequency) and volume (intensity) as well as your speech discrimination score. By integrating the results we are able to determine if the hearing loss is due to a mechanical obstruction of the middle ear (conductive hearing loss) or an impairment of the hearing cells in the inner ear (sensorineural hearing loss).
