Children’s Hearing Test
A variety of tests can be used to determine the degree, type and configuration of your child’s hearing difficulties. It is recommended to establish a baseline for your child’s hearing and check hearing every 12 months or if there are any concerns. Price – $120
Our Children’s Hearing Tests are available for children from Prep up.
Pure Tone Audiometry
The key hearing test for identifying hearing thresholds involves listening to frequency specific beeps and whistles (called pure tones) and signalling when you can hear them. Pure tone audiometry uses both air and bone conduction audiometry.
An extension of the hearing check also marked on an audiogram is called pure tone audiometry. This involves listening to a range of beeps and whistles, called pure tones, and signalling when you can hear them
Air Conduction – is measured by pure tones played through headphones. The sounds go via the air, down the ear canal, through the middle ear and to the very delicate cochlea in the inner ear.
Bone Conduction – tests the sensitivity of the cochlea by placing a small vibrator on the mastoid bone behind the ear. This bypasses the middle ear and sounds travel through the bones of the skull to the cochlea and hearing nerves.
Both air and bone conduction tests will indicate if hearing loss stems from inner, middle or outer ear. In technical terms sensorineural or conductive hearing loss.
Tympanometry
Tympanometry is not a hearing test but is an examination used to test the middle ear pressure. It tests how well the middle ear system responds to sound, eardrum mobility and conduction bones through creation of air pressure variation in the ear canal. Tympanometry can indicate the location of a blockage responsible for hearing loss. This includes middle ear infections and if medical treatment is required.
