Audiology

 

AudiologyOur licensed audiologists are dedicated to providing quality hearing health care. We offer complete hearing evaluations and treatment for adults, children and infants. Advanced diagnostic testing, including nerve function, middle ear and balance testing, is also available when requested by the physician.

Audiology and hearing aid services

 
Audiologists at our clinics are well-trained and continue education within the field of audiology to stay current with up-to-date procedures for all hearing needs. For example, our audiologists offer many hearing aid services, such as swim molds, noise protection, hearing aids, and full hearing assessments.

Electronystagmography (ENG) testing

 
Electronystagmography (ENG) testing is diagnostic testing through eye movements recorded to assess central nervous system and inner ear function. The ENG test measures four factors. The calibration test measures rapid eye movement. The tracking test evaluates movement of the eyes as they follow an image. The positional test measures dizziness from the position of the head. The caloric tests runs cold and warm water through a small, soft tube in the ear canal to measure responses. The ENG test is the highest level of testing for ear disorders involving dizziness and/or balance problems.

Audiotory Brainstem Response (ABR) testing

To Top
An ABR, or audiotory brainstem response test, is a noninvasive test that measures brainwaves during a series of clicks that sound around each ear. This test is great for small children or infants who may be at risk for hearing loss, but not yet able to give proper responses to traditional hearing tests.

Electrocochleography (EcochG) testing to assess Meniere’s disease

 
An electrocochleography test is used to determine if the inner ear has high amounts of fluid, which can lead to hearing loss, dizziness, or tinnitus. These symptoms can also be indicative of Meniere’s disease. Patients undergoing an EcochG test will have several electrodes placed on the head. A tiny microphone with an earphone will be inserted into the ear. Then, the patient relaxes and listens for clicks. During this time, performance is measured. These results can be discussed to determine if any fluid is present and decide on the next step to take.

Pure tone audiometric and speech testing

 
Audiometric testing will play different pure tones at different degrees of loudness through headphones to determine the hearing capabilities of a patient. A speech test will determine if the patient’s ability to speak is impaired by the patient’s ability to hear. These tests may ask the patient to repeat known, two-syllable words at different degrees of loudness. The results are configured and discussed soon afterward with an audiologist or speech therapist.

Pediatric hearing testing

To Top
There are two tests used to determine a child’s hearing capabilities: visual reinforcement audiometry or conditioned play audiometry. The visual reinforcement test is best suited for children ages 5 months to 2 ˝ years. The test uses tones or sounds played from speakers to either side of the child. First, toys or colorful symbols are flashed from either side to condition the child to look. Then, sounds are played at either side at different levels of loudness. The conditioned play audiometry is best suited for children ages 2 ˝ to 4 years of age. The child is asked to sit at a table. Then, as a tone or sound is played either from a speaker or through headphones, the child is asked to place toys or games into a box. The test starts with louder tones or sounds, and then decreases in volume until the child does not respond. In both cases, the results will be evaluated for further consultation from a physician.

Industrial hearing conservation

 
Since they are concerned with preventive hearing loss, audiologists advocate and are willing to help start industrial hearing conservation programs within worksites.

Custom Ear Protection (custom ear molds for hearing aids, sleep, noise, swimming)

Ear protection can be used for sleeping, noise reduction, or swimming. Custom ear pieces are mainly used for reducing noise, but may also be used to help accentuate certain sounds or tones and made to fit cell phones or mp3 players.
