A complete audiological evaluation consists of battery of tests including pure tone air and bone conduction testing, as well as word recognition ability. The pure tone test is done to determine how sensitive your ears are to sounds at different pitches. This determines the degree of hearing loss and whether hearing loss is conductive or sensorineural.

Word Recognition Tests are given to determine your ability to hear and understand speech. This helps us to gage the overall function of the hair cells (similar to nerve endings) of the inner ear, as well as the auditory processing center of the brain. Your word recognition ability will be tested with and without background noise present.

Our testing is conducted in a sound proof room for highly accurate results. Don’t worry! Our custom designed sound suite is very large and comfortable!

Impedance is a test that evaluates your eardrum’s ability to vibrate, the pressure in the middle ear, the reflex action of the tiniest muscle in the body (stapedius), and the function of the Eustachian tube.


Otoacoustic Emissions is a test that helps us to determine the health and viability of the hair cells in your cochlea. These tiny hairs are similar to nerve endings in the organ of hearing. Often times, damage to these cells can be detected even before the actual hearing loss is noticed. This test may also be used to screen hearing in babies and other people who may be difficult to test.


Tinnitus is a medical condition characterized by a persistent noise in one or both ears. This noise may sound like a ringing in the ear, crickets, ocean roaring, thumping, or hissing. Tinnitus is a very common disorder. It is estimated that tinnitus affects 20% of people. The most common causes of tinnitus are noise damage, diabetes, and medication side effects. There is no cure at this time, but treatment is available to help you manage and control the annoyance of tinnitus. We provide testing to determine the pitch and loudness of your tinnitus and develop and individualized treatment plan for you.

Hearing aids are as individual as you are. A hearing aid that works well for Cousin John may not be at all appropriate for you. The Hearing Aid Consultation is a counseling session focused on your specific hearing needs, and the hearing devices available to fit those needs. We will discuss your potential benefit from hearing aids, which hearing aid styles are best suited for you, and the special circuits that are most appropriate for your particular hearing loss and lifestyle. You will receive honest and realistic information about the expected outcomes with hearing aids with no added hype or high pressure.

When your new hearing aids arrive, we will meet again. We will make certain that your hearing aids fit your ears properly, and they will be tested using Real-Ear SpeechMapping and programmed for your specific hearing loss. You will be fully instructed in the use and care of your hearing aids. Also, we will provide you with helpful tips on how to get adjusted to all of the wonderful sounds you will be hearing. Adjusting to new hearing aids can be a difficult process, especially if you have never used hearing aids before.

At that point, your progress will be closely followed, and the hearing aids will be fine-tuned as needed. You are encouraged to visit us as often as you need in order to get the greatest benefit from your hearing aids.

Sometimes hard of hearing people need a little more assistance. When hearing aids are not enough or not appropriate we offer devices for the TV, telephone, cell phone, doorbell, alarm clock, and many other situations to help you stay connected.


A hearing loop is a wire that circles a room and is connected to a sound system. The loop transmits the sound electromagnetically. The signal is then picked up a tiny receiver in the hearing aid called a telecoil, or T-Coil.

To use a hearing loop, you flip on the T-Switch or change to the T-Coil program in your hearing aid or cochlear implant. This activates the coil and no additional receiver is needed. Your hearing aids or implants are now able to become wireless headsets for all sound that is traveling through the sound system. You hear speech more clearly than you ever imagined.

Nearly every hearing aid we sell is equipped with a telecoil (T-Coil) for use on the telephone and in venues outfitted with Hearing Loops. Our offices are equipped with hearing loops and demonstrations are available. We sell many types of personal looping equipment in the office.
