your hearing assessment: what to expect and how to prepare

A hearing assessment by an audiologist is more than a simple hearing test. We carefully investigate your ear health, your hearing ability and how to optimise your hearing. 

Before your appointment

Take a moment to note situations or environments in which you've had difficulty hearing - for a lot of people this is understanding conversations in noisy environments like restaurants or at parties. Many people find it helpful to bring a family member or friend to the appointment to share their observations and note important details or instructions.
If you are ready to consider hearing aids, it may be convenient to contact your private health insurance company and discuss whether they will contribute to the cost.

Please note: You do not need a GP referral for a hearing assessment unless you are an Australian Government Pensioner and you want to be seen under the Office of Hearing Services Voucher Program for the first time. If you are not sure, please call us on (08) 9481 0912. 

During your appointment

Information Gathering
You will be asked about your hearing history to understand any past or current factors, including medical issues and noise exposure, which could be affecting your hearing. You will also be asked about the situations in which you are having hearing difficulty.

Ear Inspection
Your outer ear, ear canal and ear drum will be examined for any pathology or blockage. The compliance of your middle ear system (see The Ear) will also be checked using tympanometry (a simple pressure test). Where appropriate, acoustic reflex testing may be performed. The acoustic reflex is elicited by loud sounds, so the test involves listening to a series of moderately loud short beeps.
These tests are typically not invasive or uncomfortable.

Hearing Test
Your hearing will be tested in a sound treated enclosure with background noise levels reduced to those required by the current stringent Australian standards. You will be asked to indicate when you can hear 'beeps' of varying frequency (pitch) and intensity (volume) in each ear. A complete hearing test includes 'air-conduction' testing with headphones and 'bone-conduction' testing using an oscillator (vibrating sound conductor). The results of your hearing test are plotted on your 'audiogram' (see below).

Speech Discrimination Test
Your ability to discriminate speech sounds is assessed using recorded speech materials. We use this information to determine whether amplification would be beneficial to your hearing. Speech in noise tests and aided speech tests may also be used.

Review Results
Your audiologist will review your test results with you and identify whether you have a hearing loss. If you do, together you can discuss management options, which may range from seeing your GP or an Ear Specialist for medical treatment, to correct use of hearing protection, communication strategies, or recommendations for hearing aids or other assistive devices. Please take time to consider your results and any recommendations made. It is also important to discuss them with people close to you so that they can understand your situation.

What is an audiogram?


The audiogram is the basic building block for most of the hearing services provided by an audiologist. It is a standardised graphical representation of the softest sounds that you can hear (hearing thresholds) in each ear, across the pitch range of human speech.

X's represent your left ear thresholds, and O's your right ear. If all of your thresholds fall above the 20dB line, you have clinically 'normal' hearing. If some or all of your thresholds fall below the 20dB line, you have a hearing loss.

Your audiogram can be used to describe your hearing loss, as well as providing some information about the probable cause, e.g. the audiogram of a person with noise induced hearing loss looks very different to one with a with an ear drum perforation.

If you wear hearing aids, your audiogram may be used to calculate the prescribed amount of amplification you need at each frequency to improve your access to important sounds.
