Overview

We are committed to helping each patient manage their hearing loss, for effective communication with family and friends, by providing resources to minimize the negative consequences of hearing loss. We customize treatment plans based on the individual needs of each patient. Most patients can obtain substantial benefit from properly fit hearing aids. The key to this success is the expertise of the audiologist and specialists who choose and program the circuitry, motivate and educate the patient, and provide proper counseling. We work with each patient to achieve a comfortable fit and satisfaction with their new hearing! If you are not satisfied at the end of the adjustment period,  you can receive a 100% refund.

We hope to have the opportunity to help you hear the sounds you love!

Audiological Evaluations

Complete Audiologic Evaluations

Hearing tests evaluate and measure the sensitivity of a person’s sense of hearing. We employ various testing strategies to determine whether the auditory system is functioning within the normal range. Evaluations include measures of hearing sensitivity for air and bone conducted sounds, measures of speech discrimination ability, assessment of the middle ear function (impedance audiometry), and assessment of the inner ear function (otoacoustic emission testing). If hearing is deficient, testing can provide information about what type and degree of hearing loss is present. Here is a little information about some of the more common types of assessments we utilize.

Otoscopy

An otoscope is an instrument used to look into the ear canal. It is important to make sure there is no wax or infection in the ear canal before testing hearing and that the tympanic membrane, or ear drum, is healthy.

Tympanometry

Method of measuring the movement of the tympanic membrane, or eardrum. A machine generates a sound in the ear canal and gives a puff of air which allows the machine to measure how much sound is reflected back. This tells us if the ear drum functions normally as well as the status of the middle ear. It momentarily gives the patient the sensation of being in an airplane.

Acoustic Reflexes

A loud sound is presented into the ear and travels up to the brainstem. A signal is sent from the brainstem down the facial nerve into the middle ear that flexes the stapedius and tensor tympani muscles, which cause the eardrum to tense. This allows the audiologist to make sure this happens when loud sounds enter the ear. If it does not, that may indicate an abnormal function in the ear or facial nerve.

Otoacoustic Emissions (OAEs)

This test uses a machine to determine function of the cochlea, or hearing organ, specifically outer hair cell status. The outer hair cells send the message of sound to the auditory nerve. While they do this they produce a low intensity sound.  This machine measures the sound emitted in response to tones.

Air Conduction Audiometry

A headset is placed over the outer ear or squishy earplugs are placed directly into the ear canal. A pure tone signal is presented into the ear canal and the patient is asked to respond to the sound as it is presented.  An audiologist determines the softest level the patient has responded to different frequencies, or pitches, and charts them on a graph called an audiogram.  An audiologist interprets the results.

Bone Conduction Audiometry

This testing is able to measure the hearing sensitivity from the cochlea, or hearing organ, to the brain but excludes the outer and middle ear. A small vibration unit attached to a headband is placed on the bone behind the ear and a tone is presented. The patient is asked to respond to the sound and an audiologist determines the softest level the patient was able to hear the tone. This allowed the audiologist to determine if the outer ear, ear drum or middle ear is causing any hearing loss.

Speech Discrimination

This testing reveals information about how the brain is interpreting the information from the ear. The patient repeats words at a volume based on the hearing test results and comfort. This score tells the audiologist how well the patient understands in quiet and helps them discuss realistic expectations and coping strategies with patients and families.

We additionally offer High Frequency Audiometry, Reflex Decay, Tone Decay, Speech-in-Noise testing, Tinnitus Evaluations, and more diagnostic tests. Give us a call if you are looking for something specific!

 

Hearing Aids & Rehabilitation

Hearing Aid Fittings

At Hearing Associates, Inc, our highly trained professionals take care in programming your new hearing aids in a highly customized fashion. Your evaluation results, lifestyle and environmental soundscape, and personal listening goals are analyzed in order to choose the most appropriate rehabilitation plan specifically for each patient. We utilize your prescription, fitting verification methods, and individual sound preferences to cuztomize the sound of devices further. It is normal to have two patients with the same hearing loss to prefer their hearing aids set differently from one another.

Fitting Verification

When hearing aids are fit onto an ear, that person's unique anatomy can cause certain frequencies of sound to be increased and some sounds to be absorbed, and subsequently dampened in volume. Additionally hearing aids have a variety of parts that fit differently into/onto the ear that can also change some sounds. A process called Speech Mapping, is when a tiny microphone probe is placed in the ear canal and measures the sounds. This measurement will be unique to everyone, allowing the fitter to make adjustments to the device and parts in a highly specific method. This process is a fitting verification method that allows the fitter, you, and your family to see and understand benefits of hearing aids.

Hearing Rehabilitation & Adjustments

Hearing aids are just one of the tools used in an individualized hearing rehabilitation plan. For first time users, an average of 3 visits can allow the fitter to adjust parts and sound for comfort while also counseling patients and their families to give them the confindence and tools to best adapt to the hearing world. Our providers additionally recommend follow-up visits every 3 months thereafter for the first year to continue to customize the fitting and discuss questions. Hearing aids are highly customizable instruments that can be adjusted over time and provide the fitter with information to tailor the hearing aid performance to your needs. Most devices are able to be adjusted to changes in your prescription over time! We are always available to see if your hearing aids could be fit better!

Hearing Aid Repairs

We offer a range of in house repairs and work with the top hearing aid and audiology product manufacturers to ensure assistance where possible. Our staff emphasizes ongoing cleaning and maintenance after your hearing aid purchase to insure you receive optimum performance and benefit from your hearing aids.

Wax Management

Maybe it's just Wax?

Sometimes, a hearing loss could be caused by something as simple ear wax! Ear wax, or cerumen, a waxy oil made in the ear and is a normal part of a healthy ear environment! Unfortunately, in some people, wax can build up and dampen sound coming into the ear. Wax build up can be caused by many different factors, but we often find that it is caused by, or made worse, when people try to remove wax on their own....

"Don't put anything smaller than your elbow in your ear"

There is a good reason this phrase became so popular- it's true! The use of cotton swabs are one of the worst factors related to a build up, by pushing wax deeper into the ear and risking permanent damage to the ear. Additionally, the use of ear candling/coning is a "method" we strongly advise against. This is not only dangerous, it has proven to be ineffective in managing ear wax.

If you think wax could be the problem, call us to schedule an appointment!

Tinnitus

For some, tinnitus can be bothersome and distracting...

Tinnitus is the perception of a sound in the absence of sound.  It is a phantom sensation, similar to phantom limb” which is the sensation an amputated or missing limb feeling like it is still attached. People experience tinnitus in one or both ears, and even somewhere in their head. It can be described as ringing, hissing, roaring of a seashell, chirping of crickets, music, people talking, and more. It can be constant or intermittent and can fluctuate in loudness and/or pitch. 

"Phantom sounds in the head"

Any patients with tinnitus should have an audiometric assessment. Diagnostic testing should include audiography, speech discrimination testing, and tympanometry. A formal audiogram establishes a base from which to pursue more advanced diagnostic testing.

Additional audiologic measurements of tinnitus include pitch matching (matching the frequency of the tinnitus with a variety of stimuli) and loudness matching (estimating the loudness of tinnitus with a pure tone or noise). Further measurements may provide information as to whether the tinnitus can be masked by an external noise.

For those that are bothered, treatment for tinnitus may include training or habituation exercises, masking devices, and/or hearing aids. Treatment programs are created around each patient's individualized needs.

Balance Evaluations

Videonystagmography (VNG)

We offer videonystagmography (VNG) test to help determine the status of the peripheral balance system located within the inner ear. The videonystagmography (VNG) is a series of tests used to evaluate the causes of a patient's dizziness or balance disorders. Together with an extensive case history, a VNG can decipher whether or not a patient may have an inner ear disease. If dizziness and/or imbalance are not caused by the inner ear, other areas such as the brain, migraines, and low blood pressure could be the source.

How the VNG Works

VNG is short for videonystagmography. The name of the test is essentially describing that an audiologist will record eye movements using video goggles. Hi-tech video goggles with infrared cameras are worn during the test. These recordings are analyzed, looking for involuntary eye movements, called nystagmus, which is associated with inner ear disorders.

Three Parts of the VNG

The first part is testing eye movement. This checks the patient’s ability to follow a visual target. The patient follows a dot on a screen. The second part is testing for dizziness related to certain positions and motion related cells. The patient will move in different positions, such as sitting, lying down, and turning the head. The last part of the VNG measures the vestibular portions of the ears. This test looks to see if the ears are responding normally and the function is balanced between the left and right ear. This is performed using cool and warm air in the ear canal. Throughout the test cameras record the patient’s eye movements and display them on a video/computer screen. This allows the examiner to see how the eyes move which is very helpful in assessing balance system health.

Dix Hallpike Test

The Dix Hallpike is testing for dizziness related to certain positions and motion related cells. The patient will move in different positions, such as sitting, lying down, and turning the head. Throughout the test, cameras record the patient’s eye movements and display them on a video/computer screen. This allows the examiner to see how the eyes move which is very helpful in assessing movement related dizziness like Benign Paroxysmal Positional Vertigo (BPPV).

Balance Treatments

Imbalance & Dizziness

Treatment for balance problems are dependent on the cause, or possible causes, of dizziness determined by a battery of tests. Treatments may include one or a combination of the below:

  • Balance Retraining Exercises Performed at Home
  • Balance Retraining Exercises Performed with an Audiologist
  • Balance Retraining Exercises Performed with a Physical Therapist
  • Dietary Changes
  • Medication
  • More…
Positional Vertigo (B.P.P.V)

Positional Vertigo

In Benign Paroxysmal Positional Vertigo (BPPV) dizziness is generally thought to be due to debris, which has collected within the wrong part of the inner ear. This debris can be thought of as "ear rocks" or “crystals”, although the formal name is "otoconia". Otoconia are small crystals of calcium carbonate derived from a structure in the ear called the "utricle". The utrical and saccule, or “gravity detectors” use these crystals to pull their sensory cells toward the ground with gravity. (While the saccule also contains otoconia, they are not able to migrate into the canal system.) Crystals migrate into one of the semicircular canals. These three canals are the “motion detectors.” When the crystals enter they cause the sensory cells to react abnormally causing dizziness or imbalance.

What causes BPPV?

The cause of BPPV is often unknown. The utricle may have been damaged by head injury, infection, or other disorder of the inner ear, or may have degenerated because of advanced age. Normally otoconia appear to have a slow turnover. They are probably dissolved naturally as well as actively reabsorbed by the "dark cells" of the labyrinth (Lim, 1973, 1984), which are found adjacent to the utricle and the crista, although this idea is not accepted by all (see Zucca, 1998, and Buckingham, 1999).

BPPV is a common cause of dizziness. About 20% of all dizziness is due to BPPV. While BPPV can occur in children (Uneri and Turkdogan, 2003), the older you are, the more likely it is that your dizziness is due to BPPV. About 50% of all dizziness in older people is due to BPPV. In a recent study, 9% of a group of urban dwelling elders were found to have undiagnosed BPPV (Oghalai et al., 2000).

What are the symptoms?

The symptoms of BPPV include dizziness or vertigo, lightheadedness, imbalance, and nausea. Activities that trigger symptoms will vary among persons, but symptoms are almost always precipitated by a change of position of the head with respect to gravity. Getting out of bed or rolling over in bed are often common "problem" motions. Since people with BPPV often feel dizzy and unsteady when they tip their heads back to look up, sometimes BPPV is called "top shelf vertigo." Women with BPPV may find that the use of shampoo bowls in beauty parlors brings on symptoms. An intermittent pattern is common. BPPV may be present for a few weeks, then stop, and then come back again.

How is it treated?

BPPV can be treated with specific exercises performed with an audiologist that move the crystals into an area that does not cause symptoms. BPPV can also resolve on its own by "dark cells" of the labyrinth actively absorbing the crystals.

How the Ear Works

Sound waves are collected by the outer ear and are funneled through the ear canal to the eardrum. Sound waves cause the eardrum to vibrate. Attached to the eardrum is one of the three bones found in the middle ear. These bones, called the ossicles, transmit and amplify the vibrations to the oval window of the inner ear. When vibrations enter through the oval window, the fluid in the inner ear creates a wave. These waves stimulate pitch specific nerve endings, called hair cells, which send an electrical impulse to the nerve. Electrical impulses are transmitted along the auditory nerve to the brain. The brain interprets the impulses into a meaningful message.
