AUDIOLOGY/ HEARING

Specialized Tests

How we test adults

A hearing test determines whether a hearing problem exists and identifies the source and severity of the problem. A complete evaluation consists of responding to tones and words and a check of the middle ear system. Test results will be explained as well as counseling and treatment recommendations. We may recommend that you see an otolaryngologist either to treat a medical problem or to obtain clearance for fitting of a hearing aid.

How we test children

A child’s hearing test involves a check of their hearing and of the middle ear system. A baby or toddler is trained to respond to a sound by looking toward a flashing toy. Older children are trained to place a block into a bucket or peg board for each sound. The results, counseling and treatment recommendations are discussed with the child’s parent or guardian.

Children with a permanent hearing loss will be referred to an otolaryngologist prior to being fit with a hearing aid. They are also are offered a referral for services from the Atlantic Provinces Special Education Authorities (www.apsea.ca). APSEA provides educational services, programs, and opportunities to children and youth who are deaf or hard of hearing and who reside in Atlantic Canada.
These services are also available to the Francophone children through the New Brunswick Department of Education.

How we test newborns

We screen every baby born in our hospital so we can find those who cannot hear well early. Then we can help them.
There are two tests available to screen babies for hearing loss. Both of these tests are safe, comfortable and only take a few minutes; most babies will sleep through it.

One test routinely used is called otoacoustic emissions (OAE’s). An earpiece is placed in the baby’s ear, soft sounds are played and a response is measured. When an echo-like sound is reflected back into the ear canal, the baby’s hearing should be normal.

A second screening test called an Automated Brainstem Evoked Response (ABaer) is sometimes necessary as well. Sticker electrodes are placed on the back of the head and neck. These electrodes measure the brain’s response to quiet sounds presented through earphones.

There are many reasons why the baby may not pass the screening: if the baby is not quiet enough during the screening, if there is noise in the nursery or if there is fluid in the ears.
If we cannot get the necessary results, you will be given an appointment to return to the audiologist for further testing.
