Specialized Audiology Testing in Phoenix

Specialized Audiology Testing for Babies, Children & Adults

At ABHA, we are highly experienced at performing specialized audiology testing of all types, including ABR, OAE, EcochG and more. After our licensed audiologist has consulted with you, conducted the otoscopic ear exam, and analyzed your results from the standard hearing test, we may need more information to determine the best course for your hearing health. Specialized hearing tests hone in on specific functions that are not covered in standard hearing tests. Like the two standard hearing tests we offer at ABHA – pure tone and speech recognition – specialized hearing tests are non-invasive and painless, and may be conducted on adults and children alike.

Auditory Brainstem Response (ABR):

abr-baer hearing testing phoenixWith normal hearing, inner ear cells transmit neural signals via the brainstem to the brain to be recognized as sound. In some cases of hearing loss, a malfunction may be found in this process. The ABR test assesses the function of the brainstem, as well as the neural passages from the inner ear.

During this test, you will be asked to wear earbuds and relax on a flat surface in a sound booth, while your audiologist attaches electrodes to your ears and forehead. Through the earbuds, you will hear a series of soft clicks. Your audiologist records your brain activity in response to these clicks, which will give them an indication of the function of this neural system.

Otoacoustic Emission Test (OAE):

The OAE test, like the ABR, requires that you wear soft earbuds and listen to a series of clicks played by your audiologist. This test measures the function and the response of your inner ear hair cells when subjected to stimulation. The OAE is useful to determine early onset of hearing loss, as well as hearing loss in very young children.

Electrocochleography (EcochG):

Within the inner ear, sound waves are converted to electric signals that are sent to your brain to register as sound. The malfunction in this conversion process may be a cause of hearing loss. The EcochG test analyzes the electric potentials generated by your inner ear hair cells, as a potential indicator of your type of hearing loss, as well as a sign of related conditions, such as Meniere’s disease. Because this test also studies fluid accumulation of the inner ear, it doubles as a test of balance. Again, you will be asked to lie down in a sound booth, while your audiologist attaches electrodes to your head and ear area. Clicking sounds are played through headphones.

OSHA Hearing Tests

The Occupational Safety and Health Administration (OSHA) estimates that approximately 30 million people in the US workforce are exposed to dangerous levels of sound each year. Depending on the environment, an eight hour workday in which a worker is exposed to noises of 80 decibels continuously may permanently damage hearing. In response to the high levels of occupationally-related hearing loss, OSHA has initiated a hearing conservation program which includes an audiometric testing program (hearing test) that regularly monitors a worker’s hearing.

Based on the level of noise in the workplace, OSHA requires that employers provide OSHA-approved hearing tests for their employees. These regular hearing tests keep a record of work-related hearing loss cases (with adjustments made to hearing loss caused by aging) and also inform employers and employees of protective measures they must take. Arizona Balance and Hearing Aids provides OSHA hearing tests for employees, in accordance with OSHA standards. Whether you are an employer or an employee, contact us today to schedule occupational hearing tests.

Specialized Hearing Tests for Children

  • Visual Reinforcement Audiometry (VRA):

    The VRA test is similar to the pure tone audiometry test, and it is used specifically for children between six months to three years of age. The VRA test is used for people of this age as they may not be able to respond accurately to sounds cued by audiologists. During the course of this painless test, your child will be trained to respond by looking for a lighted toy when s/he hears a sound. Your audiologist will play sounds via headphones to your child and gauge your child’s reactions to the series of sounds.

  • Conditioned Play Audiometry (CPA):

    cpa-test hearing testing for children phoenixLike the VRA test, the CPA test is used for young children, specifically between the ages of three to five years. Because hearing tests tend to quickly bore children of this age, the “play” aspect keeps them engaged and responsive. Your child may be asked to hold a wooden block to his or her ear, and each time they hear a sound, they’ll be asked to drop the wooden block into a bucket. This is just one example of “play” that is used in the CPA to determine the hearing ability of your child. With this test, your child will be wearing headphones and the audiologist will play a series of sounds.
