Los Altos

Silicon Valley’s Most Trusted Hearing Care Experts in the Heart of Los Altos

Our community leads the world when it comes to technology.

But as we all know, the microchips and tech are only part of the equation. The thing that makes Silicon Valley so special is the human intelligence and persistence that strive to make the impossible happen.

Hearing care is very much the same.

Although great hearing technology is important, the much more important part of achieving better hearing is partnering with the right experts to personally work with you and care for your hearing health.

Having cared for tens of thousands of incredible people since 1977, Pacific Hearing Service are the most trusted hearing care experts in Silicon Valley, trusted by thousands of patients, leading organizations, and many local physicians.

You’ll also have the added benefit of working with a team of experts that is passionate about “giving back” with a program to support low-income adults within the area and regular humanitarian trips in some of the poorest countries in the world.

If you are concerned about your hearing, then you can request a no-obligation callback from a hearing care expert today, or schedule an appointment for a comprehensive hearing assessment.

We look forward to seeing you soon.

When Was Your Last Hearing Test?

Although we all regularly have our teeth checked, our cholesterol tested, and get a yearly physical, hardly any of us regularly test our hearing.

Yet with 1 in 8 Americans now having some form of hearing loss, we’re passionate about raising awareness of healthy hearing and of the first signs of hearing loss.

The Advancements in Hearing Technology

People are often surprised to learn that today’s hearing technology is very different from what they expect.

Hearing technology has progressed at the same pace as much of the technology that our community is famous for. Gone are the obtrusive devices of yesteryear. Now, with small and discreet designs, incredible sound quality, and features including smartphone connectivity and rechargeability, hearing devices are tiny technological marvels.

Tinnitus Treatment


Speak to a Hearing Professional about Tinnitus

The perception of sound in our head or ears affects most of us at one time in our lives. Persistent ringing, humming, hissing, or buzzing can be one of the most frustrating issues. But there is hope.

We’ve developed a thorough diagnostic hearing and tinnitus evaluation to determine not only the causes, but to develop a plan using a multiplicity of available therapies. No one has to accept the old adage, “You’ll just have to live with it.”

"A friend recommended that Debbie should talk to the experts at Pacific Hearing Service. This is where she met Dr. Clark, clinical audiologist at the Los Altos office.

“She’s wonderful,” Debbie says. “She figured out that I have a weirdly shaped right ear. She made wearing hearing devices comfortable.”

Dr. Clark also introduced Debbie to a new brand of hearing aid, Widex. Since then, she’s never thought about switching to another manufacturer. “I can’t tell I have them in my ears, so I wear them all the time,” Debbie says. “And I know that’s important for the health of my brain.”

Today, she’s happy to let others know about her hearing aids. “I don’t hide them,” she says. “I liked that I could get them in red. My parents had ‘hearing aids.’ I call these ‘my ears.’”
