Hearing Assessment

A hearing assessment evaluates your hearing threshold (softest audible sound) at different pitches, as well as your speech discrimination at normal conversational and amplified levels. Additionally, Impedance testing, the assessment of the middle ear, is also carried out which helps ascertain information about the function of the tympanic membrane, the ossicular chain and the Eustachian tube (the tube that connects the ear to the throat and helps equalise pressure when diving for instance).

These tests help determine the type and degree hearing loss, the possible causes of hearing deterioration, and help us choose the appropriate treatment for you.

A hearing assessment is painless, simple, not invasive and quick.

Cochlear Implants


Assessments, rehabilitation and mapping, service, repair.

A Cochlear Implant is a surgically implanted electronic device that gives back the sense of hearing to people who do not receive enough benefit from hearing aids to manage in their every day life.

A Cochlear Implant consists of an implanted portion, which is inserted, and an external portion, which picks up, analyses and transmits sounds to the implanted portion.

Hearing with Cochlear Implants has improved dramatically, however mapping appointments and practice in hearing are required to improve tolerance and outcomes.

The implant is inserted by an ENT surgeon and programmed regularly by an audiologist.

Health fund and other rebates may apply to the surgery and device itself.

Tinnitus Assessment

Tinnitus characteristics and hearing thresholds vary among individuals. Therefore, a tinnitus reaction questionnaire (TRQ), audiological and tinnitus assessment is needed in order to gain a better understanding of the issue and help identify the most appropriate form of management.


An audiological assessment identifies the degree of hearing loss in one or both ears and a tinnitus assessment involves matching the pitch and volume of a pure tone presented through the audiometer to the patient’s perceived tinnitus.

Bone Anchored Hearing Aids (BAHA)

A Bone-Anchored Hearing Aid converts sound into vibrations which are directly transmitted to the inner ear. A titanium “post” is surgically set into the mastoid bone (the bone just behind the ear) with a small abutment exposed. A sound processor attaches to this abutment and transmits sound through the skull bone to the inner ear, thereby allowing those who would otherwise not be helped by a conventional hearing aid, to hear again. The tiny post and abutment are put in place by an ear nose and throat (ENT) surgeon and the processor is programmed and fit by an audiologist. Health fund and other rebates may apply. The audiologists at Precision Hearing are qualified in assessing if you are a BAHA candidate as well as programming and fitting the sound processor.


Suitable candidacy includes:

  • When the hearing loss is conductive in nature
  • Single sided deafness
  • People with ear malformations, i.e. when there is no ear canal or middle ear
  • Chronic external or middle ear infections where a conventional hearing aid could not be used.

Vestibular Assessment

The inner ear’s vestibular organs and associated nerves and brain centres serve many functions and can be affected by a number of outside systems. A comprehensive history is taken along with a selection of several different kinds of specialised tests which are carried out by a specialised audiologist.


These include:

  • Dizziness questionnaire: this helps identify frequency and severity of dizziness symptoms and associated lifestyle changes.
  • Hearing assessment: This is an important part of vestibular diagnoses because of the close relationship of the inner ear hearing and balance organs. These assessments include: pure tone audiometry (PTA), speech discrimination testing and middle ear function testing (tympanometry and acoustic reflexes).
  • Electrocochleography (ECochG): This is a technique of recording electrical potentials generated in the inner ear and auditory nerve in response to sound stimulation using an electrode placed in the ear canal or tympanic membrane. This test is used to detect elevated inner ear pressure or for the testing or monitoring of inner ear and auditory nerve during surgery.
  • Vestibular evoked myogenic potentials (VEMP) assessment: This test is used to evaluate whether the otolith organs (Saccule and Utricle) and vestibular nerves (Inferior and Superior) are intact and functioning normally.
  • Dix-Hallpike assessment: This is a diagnostic manoeuvre used to identify Benign Paroxysmal Positional Vertigo (BPPV).
  • Videonystagmography (VNG): This is the most common test administered to people with dizziness, vertigo and/or balance disorders. It is a group of eye movement tests that looks for signs of vestibular dysfunction or neurological problems. It measures nystagmus and other eye movements using an infrared video camera mounted inside goggles that the patient wears.

Evoked Responses

Including Electrocochleography (ECochG), Auditory Brainstem Responses (ABR), middle and late latency response.

An ECochG is looking for an indication of the presence of endolymphatic hydrops. The test records the response of the cochlea and the firing along the auditory nerve.

An ABR is most commonly used to test for retrocochlear function as well as test hearing thresholds for clients who cannot carry out a behavioural test as well as for workers compensation clients.

Otoacoustic Emission Testing

Establishing outer hair cell function due to ototoxicity and/or noise exposure. It is also a useful estimate of hearing severity and reterocochlear function.

Perilymph Fistula Test (PLF)

PLF is a small defect in the bony covering of the oval or round windows, creating abnormal communication between the fluids of the inner ear and middle ear cavity. This test uses a machine that changes the middle ear pressure quickly. If a PLF is present, the client will experience slight dizziness upon pressure change.

Dix Hallpike Manoeuvre

This is a diagnostic maneuver used to identify positional vertigo.

Customised Hearing Protection

Including musicians earplugs and swim plugs.
Here at Precision Hearing we strongly believe in conservation of hearing and provide hearing protection with varying attenuation to suit your needs without affecting the quality of sound: whether you are a musician or enjoy car races on weekends.
