About Microtone Audiology, Inc.

Just For You

When it comes to your hearing, a cookie cutter approach simply won’t do.

Everything about your hearing is specific to you… from the shape of your ears to the auditory environment to which you’re exposed. Even the way you brain perceives and process what you are hearing is unique to you. If that uniqueness isn’t accounted for, then your hearing solution may be incomplete or even flat out wrong. Worse yet, a misdiagnosed condition could overlook a broader health issue, or squander the opportunity to slow down or even reverse your hearing loss.

Our goal at Microtone is to provide the very best care available to our patients. We stay informed about all of the latest technological and scientific developments in our industry. We hand-pick only the highest quality, most versatile, and contemporary solutions. We also use the most sophisticated testing and diagnostic equipment that exists, ensuring that not only do you have the right device for your needs, but it is fitted and programmed perfectly for you.

All About You

Microtone’s primary focus is on the wellness of our patients, rather than merely selling hearing aids. Our patient-first approach is the DNA of our practice and dictates everything we do, from our comprehensive testing to our personalized fitting to the free care and maintenance we provide for the lifetime of every hearing aid we sell.

Best of all, we employ Doctors of Audiology who are trained to identify not only hearing loss, but hearing disorders and medical conditions involving the outer, middle, and inner ear. This makes dispensing hearing aids a part of our practice and not the sum of what we do. Our other services include:

  • Comprehensive hearing evaluations for both adult and pediatric populations
  • Tinnitus evaluation and consultation
  • Aural rehabilitation
  • Balance function testing
  • Hearing conservation and custom ear protection

Our diagnostic testing and exams will routinely identify medically treatable hearing conditions that a dispenser might otherwise miss. With many of these conditions, time is of the essence and delaying treatment can result in increased, irreversible damage. We partner with multiple Ear Nose & Throat Physicians in the community, so that we can quickly get you the treatment you really need in order to help you avoid unnecessary hearing loss.

When it comes to your hearing, would you rather be treated as a consumer or a patient? At Microtone, we think your hearing is too precious to treat as a commodity.

There For You

At Microtone, we don’t just sell you something and send you on your way. Instead, we are there for you from start to finish. We help you identify your specific issues. We will educate you on possible solutions and help you choose the right option that fits both your budget and needs.
Should you need to be fitted with hearing aids, all of our devices include our lifetime service plan, which includes regular follow up visits to clean and/or adjust your device at no extra charge.

Get the right solution, along with the best care and service and a great team of folks that will be there for you on Your Journey to Better Hearing.
