Expert Audiology Care Across Southern & Central California

Real Ear Measurement (REM) is the gold standard for hearing aid fittings. It measures exactly how sound is amplified in your unique ear canal, ensuring your hearing aids are programmed to your specific hearing loss—not generic factory settings. Dr. Mendoza uses REM for every new fitting and annual check-up, a best practice many audiologists skip. This precise verification is the difference between hearing aids that work and hearing aids that sit in a drawer.

Common signs include frequently asking people to repeat themselves, difficulty hearing in restaurants or group settings, turning up the TV volume, missing parts of conversations, or feeling exhausted after social events. If you're experiencing any of these symptoms, a comprehensive hearing evaluation can determine your hearing loss type and level. Many people wait 7-10 years before seeking help—don't let hearing loss impact your quality of life unnecessarily.

We offer all the top hearing aid brands including Phonak, Widex, Starkey, Oticon, ReSound, Signia, and Unitron. This ensures you get the best technology for your specific needs and lifestyle rather than being limited to one manufacturer. We'll help you find the right solution based on your hearing loss, budget, and preferences—not our inventory.

A comprehensive hearing evaluation typically takes 45-60 minutes. We conduct testing in our advanced hearing booth to accurately identify your specific hearing loss type and level. This includes audiometry, speech testing, and may include otoacoustic emissions testing. We'll review your results, answer all your questions, and discuss treatment options during the same appointment. An accurate evaluation is essential before purchasing hearing aids.
