Regular maintenance and cleaning are an important part of prolonging the longevity of your device, ensuring it’s working to its best potential.
19-point Hearing Aid Tune-up
Prescription hearing aids are a long-term investment.
Without regular cleaning, the performance of your devices will begin to deteriorate, and it won’t be long until you notice the difference in your hearing.
At Pacific Hearing Service, our experienced and highly qualified audiologists and staff follow a methodological approach that evaluates all aspects of your devices.
If you have noticed that you are not hearing as well as you used to with your prescription hearing aids, the 19-point inspection will help us determine if they are malfunctioning or if we need to evaluate your hearing for possible changes.
The 19-point inspection is the best way to keep your hearing aids working up to specifications, ensuring you are getting the maximum benefit from your devices.

The 19-point inspection is our way of ensuring that you get the best possible performance from your hearing devices throughout their entire life.
