Auditory Brainstem Response (ABR)
Auditory Brainstem Response (ABR) testing is useful in demonstrating the softest mid to high pitched sounds the hearing system can respond to. The test takes approximately one hour. Four electrodes are attached to the scalp and headphones placed in the ears. Clicking sounds are presented at various loudness levels and a response is measured on a computer. The response allows the audiologist to determine how efficiently sound is moving through the hearing system.

Electronystagmography (ENG)
The balance system is a complex one involving coordination of the vestibular (inner ear), visual (eyes), and the sensory nerves throughout the body. The ENG is one method utilized to evaluate problems with balance and equilibrium.

Oto-acoustic emission (OAE)
Oto-acoustic emission (OAE) evaluation is an evaluation of cochlear function (the sensory organ of hearing). OAE is a fairly new but very reliable test. A normal cochlea will emit an echo when a sound is presented. Earphones are placed in the ear canal and a clicking sound is presented in the ear. A computer monitors the ear for a response which enables the audiologist to determine if the cochlea is functioning normally. An OAE evaluation takes approximately 30 minutes.

Pediatric Hearing Evaluations
Infants hear and listen from the moment of birth. Good hearing is essential for your baby to learn to talk. Pediatric hearing evaluations can be performed at any age. There are many sophisticated tests that can determine the level of your child's hearing. If you feel there is concern, contact our Audiology Department at 704/295-3300.

Cochlear Implant Evaluations & Rehabilitation
Cochlear implants are electronic devices surgically implanted in individuals who are deaf and can no longer benefit from conventional hearing aid technology. A thorough examination by both an audiologist and physician can help to determine if a person is a qualified candidate for this type of procedure.

Visual Conditioned Response Audiometry (VRA)
VRA is effectively used from a few months of age up to approximately three years old. The child is seated at an angle to a speaker and animated toy. The child is observed by an audiologist for either a conditioned response or other reactions to a variety of test sounds. The patients response levels are adjusted for their age and the hearing level is estimated.

Auditory Steady State Response (ASSR)
Performed in a similar manner as ABR, ASSR can be recorded in neonates and children. They are evoked by frequency specific tonal stimuli, can be detected objectively using statistical algorithms, have thresholds that are highly correlated with behavioral audiometric thresholds, and can be used to estimate the behavioral audiogram.

Implantable Hearing Aids
Implantable hearing aids are devices for patients who cannot utilize conventional hearing aids. These devices are surgically implanted either in the middle ear or mastoid to help over come certain types of hearing losses. A thorough evaluation from both an audiologist and neuro-otologist can determine if you are a good candidate for one of these hearing aids. Please contact our Audiology Department at 704/295-3300 for more information.

Tinnitus Re-Training Therapy
Tinnitus is the bothersome ringing in the ear often described as roaring or crickets. The purpose of tinnitus re-training therapy is to habituate the perception of tinnitus through counseling, sound therapy and life-style modification.
