Pure Tone Audiogram (PTA)
This is the subjective hearing test. This tests your hearing across a range of calibrated frequencies. It involves listening to sounds via head/earphones and bone conductor transducer and responding by pressing a button every time you hear a sound.
Tympanometry (Tymps)
This is a quick test used to test the function of your tympanic membrane (ear drum) and your middle ear. It involves placing small plugs in your ears.
Acoustic Reflex Testing (ARTs)
This is an extended version of the tympanometry testing and this tests your middle ear muscles reflexes and sound transmission to the brain. It may include listening to some loud noises.
Otoacoustic Emissions (OAE)
This is a valuable test that assesses your hair cell function in the cochlear (hearing organ in the inner ear). It involves listening to a clicking sound or a combination of two tones for a few minutes.
Auditory Brainstem Response (ABR) - threshold/neurological/screening
This is a hearing test that assesses sound transmission along the whole hearing pathway, from the ear to the auditory area in the brain. It involves listening to a clicking sound through headphones. The results are recorded automatically using four sensors that are placed on each ear and on your forehead.
Auditory Cortical Response (ACR/CERA)
This test is very similar to the ABR, but it can give us specific frequency information.
Auditory Steady State Response (ASSR)
Frequency specific stimuli is used with the aim of creating an estimated threshold hearing test.
Speech Testing
This is a test that assesses your ability to understand speech using single words. It involves listening to words and repeating what you have heard to the audiologist who records the results.
