The 7 Types Of Hearing Aid Tests And What They Mean

If you are planning on taking a hearing test in Sydney, you may want to know what you are in for

A hearing test in Sydney is done to determine what exactly is the degree of hearing loss and what should be the further course of treatment. If you have visited an audiometrist in Australia complaining about not being able to hear clearly, or having difficulty processing sounds, you will be recommended a hearing test. 

There are many different kinds of tests that can assess the ability to hear and chart out results. 

These will be discussed in detail. 

Pure Tone Testing 

This test measures the ability to hear sounds of various pitches and volumes by using air conduction. 

How is it done? 

  • The Pure Tone test is done by asking you to wear headphones
  • Sounds of various pitches and frequencies are then sent through the headset
  • You are given a device with buttons, wherein each time you hear the sound, you press the specific button
  • An audiogram is then charted out with the results 

Bone Conduction Testing 

In this method, the response of the inner ear to sound is checked

How is it done? 

  • A device is placed behind the ear
  • Vibrations are sent to the inner ear 
  • The inner ear’s ability to receive sound is checked 
  • Instead of the passage of sound through air, the passage of sound through the bone is checked 

Otoacoustic Emissions (OAEs)

In the inner ear is the cochlea and there are numerous hair cells present in this region that play a vital role in how sound is perceived. 

How is it done? 

  • A probe that has a mic attached to it stimulates the cochlea
  • A speaker is also present in the arrangement to magnify the sound 
  • The hair cells in the cochlea vibrate when they receive a sound, and this vibration is recorded by the device
  • If the hearing is flawless, emission will be produced 
  • In those who are experiencing hearing loss, there will be no emissions 
  • Through this test, the functioning of the inner ear is determined. If there are blockages, or fluid is present etc. 

Auditory Brainstem Response (ABR)

Typically done for those who are not able to communicate whether they are able to hear sounds or not. 

How is it done? 

  • Electrodes are placed on the scalp or the earlobes
  • Sounds of various degrees and frequencies are used 
  • The brainwave activity is measured and recorded on a chart
  • This type of test is done when sensorineural hearing loss needs to be measured

Tympanometry 

A common test done by the hearing aid specialist when you visit, tympanometry determines whether the passage of sound through the middle ear is happening accurately. 

How is it done?

  • The eardrum is a sensitive portion that is present in the region of the middle ear
  • On receiving sound, it vibrates
  • The tympanometry test measures if this is still happening

Acoustic Reflex Testing 

The muscle contraction that takes place in the middle ear is tested. 

How is it done? 

  • A probe that is attached to the ear sends sounds 
  • The muscles in the middle ear are bound to involuntarily contract in normal circumstances 
  • These contractions are measured by a device
