There are two big misconceptions that many people make about hearing loss.
The first misconception is that hearing loss is a sign of being broken. This is wrong.
The truth is, hearing loss is often a sign that you’ve lived an abundant, rich life and experienced so many great things that your ears have struggled to keep up with you.
In the same way that driving your car fast will result in you having to change the tires sooner, hearing loss is often a result of leading a fast-paced life.
At Pacific Hearing Service, this often results in incredible people walking through our door with a story to share, and it often results in us being fortunate enough to not just care for people’s hearing but to also make new friends in the process.






The second misconception is that hearing devices alone are the solution to a hearing loss.
Great hearing technology is certainly a critical part of the equation but a small part of the puzzle when compared to the importance of working with the right experts.
As our community knows better than most, technology without human intelligence does not change the world. The combination of the two does.
With over 40 years’ experience caring for tens of thousands of patients throughout Silicon Valley, Pacific Hearing Service is trusted by patients, physicians, and many local organizations.
