Why Choose Us

What Sets Us Apart From Our Competition?

We offer the best-case scenario. Doctoral level audiologists working in conjunction with Fellowship trained and Board Certified Otolaryngologists (ENTs).  If your hearing loss presents with an underlying medical condition, our ENT’s can work with your audiologist to treat your condition.  The ENT and audiologist will work as a team for optimal results.  Additionally, if issues arise once you are fit with hearing aids the ENT will available to provide any necessary medical intervention.

Do You Need a Hearing Test?

Hearing loss can come on so gradually, you may not even realize it’s happening. This online quiz can help you decide if you are hearing less than you should be.

What to Expect

A combination of your medical history, examination of the ears, and diagnostic tests will enable the audiologist to determine what is going on with your hearing.

What we do

Our Services

Hearing Aids

A hearing aid is a small electronic device that you wear in or behind your ear. It allows the person with a hearing loss to communicate, and participate more fully in daily activities. 

Hearing Testing

We test your hearing to determine if you have hearing loss, the cause and type of hearing loss and which ear the loss is in. We can then determine the most suitable treatment options.

Otoacoustic Emission Testing

Otoacoustic Emission Testing

Otoacoustic emissions (OAE)’s are low-level sounds generated by the outer hair cells of the cochlea (inner ear) in response to auditory stimuli. OAEs are present in nearly all normal-hearing ears. Absent OAEs indicate hearing loss and/or middle ear pathology.

When are OAE tests used?

OAE tests are used to assess the following:

  • Infants from newborn to children up to 4 years of age
  • Children and adults who are or who are unable to cooperate with other methods of testing
  • Hearing testing (e.g. individuals with autism or stroke)
  • Children with developmental or delayed speech or language disorders
  • Individuals with tinnitus, acoustic trauma, noise induced hearing loss, or sudden hearing loss
  • Individuals with abnormal auditory perception
  • Individuals with sensorineural hearing loss
  • Individuals with abnormal auditory function studies or failed hearing exam
  • Potentially malingering individuals who may be feigning a hearing loss
  • Monitoring of ototoxicity in patients before, during, and after administration of agents known to be ototoxic (e.g., aminoglycosides, chemotherapy agents)

Types of OAE’s

  • Distortion Product Otoacoustic Emissions (DPOAEs)

DPOAEs are generated by simultaneous stimulation of the outer hair cells by presenting two pure tones of different frequency through the OAE probe.

  • Transient Evoked Otoacoustic Emissions (TEOAEs).

TEOAEs are generated when the ear is stimulated by clicks or tonebursts.

DPOAEs and TEOAEs are equally reliable in the 1.5 kHz to 4 kHz range. TEOAEs are more reliable for frequencies below 1.5 kHz while DPOAEs are more reliable for frequencies above 4 kHz.

What will happen during the test?

An OAE probe with eartip is inserted into the ear canal to obtain a seal. The acoustic signal is presented from the probe. The signal travels through the ear canal, the middle ear, and finally reaches the cochlea where the outer hair cells are excited and the emission is generated. The emission travels back through the middle and outer ears and is detected by a highly sensitive microphone in the OAE probe.  Other than the annoyance of having a soft plug in your ear canal, the patient will not experience any discomfort.  Newborns will often sleep during the entire procedure.

Industrial Hearing Testing

What is Industrial Hearing Loss?

Industrial hearing loss or occupational hearing is a condition that results in the loss of hearing (often over a prolonged period of time) as a consequence of a person’s working environment.

There are a range of different types of hearing loss that can be caused from noise in the workplace, from temporary to permanent loss of hearing and conditions such as tinnitus or acoustic shock syndrome.

The Occupational Health and Safety Agency (OSHA) has in place regulations to protect workers from having to suffer from high levels of noise in the workplace. Employers that have a noisy work environment should be following the instructions as dictated in those policies. Regardless, of the specific profession, if there are consistent levels or noise above 80 dB an employer should be looking into lowering noise levels and/or providing ear protection equipment to staff.

Hearing Conservation

Noise, or unwanted sound, is a pervasive occupational health problem. Exposure to high levels of noise can cause hearing loss. The extent of damage depends primarily on the intensity of the noise and the duration of the exposure.

Noise-induced hearing loss can be temporary or permanent. Temporary hearing loss results from short-term exposure to noise, with normal hearing returning after period of rest. Generally, prolonged exposure to high noise levels over a period of time can gradually cause permanent damage.

Our hearing conservation program is designed to protect workers with significant occupational noise exposures from hearing impairment even if they are subject to such noise exposures over their entire working lifetimes.

Our center provides DOT employees with the following: provides the following:

  • Hearing evaluations for DOT physicals
  • Employee baseline testing
  • Annual hearing evaluations
  • Monitoring of threshold shifts in accordance with OSHA regulations
VNG Testing

Videonystagmography (VNG)

What is videonystagmography (VNG)?

Videonystagmography (VNG) is a test that measures a type of involuntary eye movement called nystagmus. These movements can be slow or fast, steady or jerky. Nystagmus causes your eyes to move from side to side or up and down, or both. It happens when the brain gets conflicting messages from your eyes and the balance system in the inner ear. These conflicting messages can cause dizziness.

You can briefly get nystagmus when you move your head a certain way or look at some types of patterns. But if you get it when you don't move your head or if it lasts a long time, it may mean you have a disorder of the vestibular system.

Your vestibular system includes organs, nerves, and structures that are in your inner ear. It is your body's main center of balance. The vestibular system works together with your eyes, sense of touch, and brain. Your brain communicates with the different systems in your body to control your balance.

Other names: VNG

What is it used for?

VNG is used to find out if you have a disorder of the vestibular system (the balance structures in your inner ear) or in the part of the brain that controls balance.

Why do I need a VNG?

You may need a VNG if you have symptoms of a vestibular disorder. The main symptom is dizziness, a general term for different symptoms of imbalance. These include vertigo, a feeling that you or your surroundings are spinning, staggering while walking, and lightheadedness, a feeling like you are going to faint.

Other symptoms of a vestibular disorder include:

  • Nystagmus (involuntary eye movements that go side to side or up and down)
  • Ringing in the ears (tinnitus)
  • Feeling of fullness or pressure in the ear
  • Confusion

What happens during a VNG?

A VNG may be done by a primary health care provider or one of the following types of specialists:

  • An audiologist, a health care provider who specializes in diagnosing, treating, and managing hearing loss
  • An otolaryngologist (ENT), a doctor specializing in treating diseases and conditions of the ears, nose, and throat
  • A neurologist, a doctor specializing in diagnosing and treating disorders of the brain and nervous system

During a VNG test, you will sit in a dark room and wear special goggles. The goggles have a camera that records eye movements. There are three main parts to a VNG:

  • Ocular testing. During this part of the VNG, you will watch and follow moving and nonmoving dots on a light bar.
  • Positional testing. During this part, your provider will move your head and body in different positions. Your provider will check if this movement causes nystagmus.
  • Caloric testing. During this part, warm and cool water or air will be put in each ear. When cold water or air enters the inner ear, it should cause nystagmus. The eyes should then move away from the cold water in that ear and slowly back. When warm water or air is put in the ear, the eyes should move slowly toward that ear and slowly back. If the eyes don't respond in these ways, it may mean there is damage to the nerves of the inner ear. Your provider will also check to see if one ear responds differently from the other. If one ear is damaged, the response will be weaker than the other, or there may be no response at all.

Will I need to do anything to prepare for a VNG?

You may need to make changes in your diet or avoid certain medicines for a day or two before your test. Your health care provider will let you know if there are any special instructions to follow.

Are there any risks to a VNG?

The test may make you feel dizzy for a few minutes. You may want to make arrangements for someone to drive you home, in case the dizziness lasts for a longer period of time.

What do the results mean?

If the results were not normal, it may mean you have a disorder of the inner ear. These include:

  • Meniere's disease, a disorder that causes dizziness, bouts of hearing loss, and tinnitus (ringing in the ears). It usually affects only one ear. Although there is no cure for Meniere's disease, the disorder may be managed with medicine and/or changes in your diet.
  • Labyrinthitis, a disorder that causes vertigo and imbalance. It is caused when part of the inner ear becomes infected or swollen. The disorder sometimes goes away on its own, but you may be prescribed antibiotics if you are diagnosed with an infection.

An abnormal result may also mean you have a condition that affects the parts of the brain that helps control your balance.

If you have questions about your results, talk to your health care provider.

Is there anything else I need to know about a VNG?

Another test called electronystagmography (ENG) measures the same type of eye movements as a VNG. It also uses ocular, positional, and caloric testing. But instead of using a camera to record eye movements, an ENG measures eye movements with electrodes placed on the skin around the eyes.

While ENG testing is still being used, VNG testing is now more common. Unlike an ENG, a VNG can measure and record eye movements in real-time. VNGs can also provide clearer pictures of eye movements.

“I have been going to ASC for 6 years and I’m completely satisfied with the hearing aids that I have received. I am on my third set of hearing aids that get better and better over the years….. not just because the hearing aids are increasing the electronic ability to fine tune the frequencies that I can’t hear otherwise. The ability to have different programs for different places is a must and the sensitivity…… is great for wind noise elimination. I send anyone I can to ASC because they are the only ones that I trust.”
