Dr. John Folmar, AuD


Bio: I practice as an audiologist, a hearing healthcare professional trained in the field of audiology. Audiologists diagnose and treat individuals suffering from hearing loss, balance disorders, tinnitus and auditory processing disorders. A graduate of Northwestern University, I earned a Doctor of Audiology (AuD) from the Arizona School of Health Sciences.  I entered the field 25-years ago.    My father, who was an Ear, Nose & Throat (ENT) surgeon in Southern California, introduced me to the profession.  My primary focus of interest has been hearing testing, hearing aids and tinnitus solutions

I have been with Peninsula Hearing Services in Burlingame for over 10 years. Previously, I worked as a researcher for a new and innovative hearing aid manufacturer in the Silicon Valley area. It was that experience where I learned the in’s-and-out’s” of hearing aids and the  challenging “journey” consumers experience seeking the best hearing aid for themselves among the vast number of advertisements on the internet, television and in print media.

I regularly test, review and fit my patients with new hearing aids released from the major hearing aid brands Oticon, Phonak, Resound, Signia, Starkey, and Widex. Information and pricing for the newest hearing aids for 2023 can be found on this website under the menu item Hearing Aids 2023.

Look for an audiologist who uses Real Ear Measures to fit hearing aids. This procedure is the only way to ensure the hearing aid programming is customized to your unique hearing loss, like a prescription for eyeglasses. A video of how real ear measure are performed can be found in the link RE Measures performed.

NEW! Widex Moment Sheer Hearing Aid

Click on the red & white button to learn why the Widex Moment hearing aid sounds so natural compared to other hearing aids. In tests, 85% of hearing aid users preferred Widex Moment across different sound scenarios.

Hearing Aid Brands

There are 6 major brands of hearing aids. Twenty years ago, there were over 40! However, most have since closed their doors or merged with today’s major brands. The remaining 6 brands have each been in business for 50 or more years and are extremely competitive with one another. Because of this, all provide excellent products, are capable of appropriately treating most any hearing loss and offer the consumer a diverse portfolio of products to meet almost any hearing need.

Choosing Hearing Aids with an Audiologist

Nobody wakes up “wanting” hearing aids. However, if you have been diagnosed with hearing loss, it is like any other medical condition that if left untreated becomes a “chronic” condition that becomes worse over time and more difficult to treat. However, the vast majority of people seek hearing aids because they feel isolated and lonely and simply yearn for the emotional relief of feeling closer to others and part of conversations and their social network again. Hearing aids also provide a huge physical relief after years of straining to hear.

As a former researcher for a hearing device manufacturer, my office has reviewed most of the hearing aids on the market and has expertise and experience with fitting them

There are generally 3 factors considered when a provider recommends a hearing aid:


Because of the miniaturization of computer chips, technological innovation and improvements in battery design, the vast majority of patients are able to wear what is known as the RIC (receiver-in-the-canal) style devices. This style is small, discreet, comfortable, has a natural sound quality, and yet is powerful enough to fit even severe hearing losses). Only the more severe hearing losses or those with chronic ear infections are fit with the older, larger BTE (behind-the-ear) style devices. There is no difference in cost between the different sizes/styles.


All of the 6 major manufacturers design technology levels for hearing devices. These levels have nothing to do with the size or appearance of the devices, but rather with the sound processing capability of the computer chip inside the hearing aids.

These technology levels drive the cost of hearing aids and are generally referred to as “standard”, “advanced” and “premium”, with standard being the least expensive and premium the most expensive. While all 3 levels are capable of providing an excellent improvement in hearing, the more advanced level features are marketed to provide ease of comfort in louder listening situations like restaurants.

A hearing evaluation is the first step needed for an audiologist to begin making a recommendation for hearing aids. Peninsula Hearing Services is in-network with all major health insurance carriers.
