Information on hearing and balance tests

As part of your consultation in the audiology department, you may have hearing or balance tests.

Before your appointment


Hearing tests are carried out for all hearing and balance patients. It is important for your ears to be checked for wax before your appointment so that this can be removed at your local GP surgery before your hearing test.

Please bring a list of current medications, and any audiology clinic letters and tests results received from other hospitals.


Please do not bring other children to your child’s appointment. We also request that only one parent /carer accompany the child into their appointment.

For young children, please bring their ‘red book’ if you can.

More information

Hearing tests

Pure tone audiometry (15 mins)

Is a hearing test to find the quietest sounds that you can hear. Different sounds are presented through headphones or a headband. You are asked to respond to the sounds by pressing a button when you hear them.

Tympanometry (5 mins)

Whilst you are sitting still a soft tipped probe is placed in your ear canal and pressure changes show how the ear drum and middle ear are working.

Acoustic reflex threshold (10 mins)

Short bursts of sound are presented through a soft tipped probe placed in your ear canal to check the working of the small, middle ear muscle.

Eustachian tube function test (10 mins)

A soft tipped probe is placed in the ear canal and records the movement of the ear drum before and after swallowing a sip of water. The Eustachian tube links the middle ear to the back of the throat and serves as a vent to equalise pressure between the atmosphere and the middle ear.

Oto-acoustic emission test (10 mins)

A clicking sound is presented to your ear through a soft probe placed in the outer part of your ear. The probe then records the reflection of sound back from the inner ear .

Speech audiometry (20 mins)

To check how well you can hear speech sounds some words will be presented to each ear in turn through headphones and you will be asked to repeat what you hear. The words are presented at medium, loud and quiet levels.   

Auditory brainstem response (ABR) test (20 mins)

This test examines the nerve of hearing as part of the hearing pathway to the brain. Sensors are placed on the skin behind your ears, on your forehead and on the top of your head.

You will then be asked to lie or sit on a couch with your eyes closed and be as relaxed as possible. Headphones will present a loud clicking noise to one ear and a rushing sound in the other. We will be measuring time taken for the sound to get to your brain and will this be repeated for both ears.

Balance tests

These tests are designed to test the function of your balance system located in the inner ears. The brain uses the information from the balance organs together with information from your eyes.

We will be looking at or recording eye movement to help us investigate your balance system.

Video-nystagmography (VNG) (20 mins)

The tests will be carried out whilst you are sitting on a couch wearing video goggles to record the eye movement. Some of the tests are carried out in the dark. Initially you will be asked to look at a small red light on a bar in front of you and follow it as instructed.

You will be asked to use your eyes to follow a red light moving from side to side in front of you and to count lights as they go past a central point at varying speeds

Caloric test (25 mins)

This important test helps determine any difference between the balance function of each ear. Eye movement will be recorded with a camera.

The test is performed whilst you are lying on a couch and by irrigating the outer part of the ear with water 7 degrees C above and then 7 degrees C below body temperature for each ear.

This change in temperature changes the density of the inner ear fluid and gives you a sense of rotation/dizziness resulting in eye movement known as nystagmus. It is this nystagmus that we are looking to observe and which lasts for a couple of minutes before gradually fading away.

Dix Hallpike Manoeuvre (10 mins)

Accumulation of calcium carbonate particles in parts of the inner ear can lead to positionally induced dizziness often occurring whilst turning in bed or looking up or down.

The Dix Hallpike manoeuvre enables us to determine whether dizziness is caused as a result of the above pathology. To carry out the test, doctor will lie the patient down quickly to stimulate the balance system, and eye movements will be observed , you may feel dizzy during this procedure.

The particles can be then repositioned to treat the problem.

Vestibular-Evoked Myogenic Potential (VEMP) (25 mins)

This a special balance test.  Three sensors are placed on the skin: on the forehead, on the neck muscle, and on the collar bone. Some sounds are played via headphones, whilst you turn your head to the side to activate your neck muscle. The activity in the neck muscle is recorded to show the function of the balance system.
