Why a Professional Hearing Aid Fitting Matters

Purchasing hearing aids is only half the equation. Without a proper fitting, even the most advanced devices may underperform or sit unused in a drawer. A professional hearing aid fitting ensures your new devices are comfortable, correctly programmed, and optimized for the environments where you spend your time.

At Optimum Audiology, Dr. Kristi Mendoza follows best practices for every fitting at our Apple Valley, Jess Ranch, Visalia, and La Verne locations. This includes Real Ear Measurement on every device—a critical verification step that many providers skip.

What Happens During Your Fitting Appointment

Your fitting begins with a conversation about your lifestyle, listening environments, and communication goals. Understanding where you struggle most—whether in restaurants, at family gatherings, or on phone calls—helps us fine-tune your settings for real-world success.

Physical Fit and Comfort

We check how the hearing aids sit in or behind your ears and make adjustments to ensure they stay secure without causing pressure or irritation. For custom devices, earmold impressions are taken approximately two weeks before your fitting to guarantee a precise fit.

Real Ear Measurement Verification

This is where Optimum Audiology stands apart. During Real Ear Measurement, a thin tube with a tiny microphone is placed in your ear canal alongside your hearing aid. We play calibrated sounds and measure the actual output reaching your eardrum. This objective data confirms your hearing aids deliver the right amplification at every frequency for your specific hearing loss.

Dr. Mendoza was trained in Real Ear Measurement by Gustav Mueller, Ph.D., a pioneer in the field. She has performed this verification for over 25 years and includes it with every new hearing aid delivery and at annual checkups. Without this step, hearing aids are essentially programmed using guesswork.

Programming and Personalization

Modern hearing aids offer extensive customization. We program multiple listening settings for different environments, adjust noise-reduction features, and connect your devices to your smartphone, if applicable. You’ll leave knowing how to switch programs, adjust volume, and care for your investment.

Flexible Follow-Up Care

Your hearing needs may change as you adjust to amplification. Optimum Audiology’s hybrid service model makes follow-up care convenient. We offer remote programming for compatible devices, curbside appointments for quick adjustments, and telehealth consultations throughout Los Angeles, San Bernardino, Riverside, and Orange Counties. You get the ongoing support you need without unnecessary trips to the office.

The Difference a Proper Fitting Makes

Hearing aids fitted using Real Ear Measurement provide better speech understanding and higher satisfaction rates. When devices are verified rather than estimated, you’re more likely to wear them consistently and experience the full benefits of better hearing.

Whether you’re getting your first hearing aids or upgrading to new technology, trust Dr. Mendoza’s expertise and commitment to best practices. Request a callback today to schedule your hearing aid fitting and experience the difference verified care makes.

Your Questions Answered

Frequently asked questions

With over 30 years of experience, we understand you may have questions about hearing health, treatment options, and what to expect from your visit. Dr. Mendoza and our team have compiled answers to the most frequently asked questions to help you feel informed and confident about your care.

Plan for 60 to 90 minutes for your initial fitting appointment. This allows time for physical adjustments, Real Ear Measurement verification, programming, and instruction on using and caring for your new devices.

Real Ear Measurement uses a tiny microphone to verify the actual sound levels your hearing aids produce in your ear canal. This objective test ensures your devices are programmed accurately for your hearing loss rather than relying on manufacturer estimates alone.

No. Studies suggest fewer than 30% of hearing aid fittings include Real Ear Measurement verification. Dr. Mendoza has performed this gold-standard test for over 25 years and includes it with every fitting at Optimum Audiology.

Some adjustment is normal as your brain adapts to amplified sound. However, the physical fit should be comfortable from day one. If you experience soreness or pressure, contact us for adjustments—hearing aids should never cause pain.

Most patients benefit from one or two follow-up visits within the first month to fine-tune settings based on real-world experience. After that, annual checkups help ensure continued optimal performance.

Yes. Many modern hearing aids support remote programming. If you have compatible devices, Dr. Mendoza can make adjustments without requiring an office visit—part of our flexible hybrid service model.

Bring your hearing test results if conducted elsewhere, a list of medications, your smartphone if you want Bluetooth connectivity set up, and any questions about your devices or hearing care.

Real Ear Measurement provides objective confirmation that your hearing aids deliver appropriate amplification. Subjectively, speech should sound clearer without being uncomfortably loud, and you should notice improvement in your most challenging listening situations.

Adjustment takes time, and fine-tuning is expected. We work with you to address concerns through programming changes or physical modifications. Most dissatisfaction stems from improper fitting—which is why we verify every device with Real Ear Measurement.

Yes. We offer curbside appointments for added convenience and concierge in-home services throughout Los Angeles, San Bernardino, Riverside, and Orange Counties. Contact us to discuss which option works best for your situation.

The care my daughter received at this facility was phenomenal. I wish every doctors office we visit would be like the staff here. The person who performed all the test for my daughter was this wonderful girl named Jasmine, she told us she was a resident at this facility, nonetheless she was awesome. Took her time with my daughter and was very kind. We also got to meet one of the Drs and he was also great. All around amazing kind staff, starting from the ladies at the front desk to staff in the back. I gave this place 5 stars because of how amazing they were. 😊

I was seen for my ears, even though I still didn't get to know what's still wrong with my ears, I'm glad to know I'm not going deaf. And the nurse, Jasmine was very helpful and she has a beautiful and bright spirit. She was very professional and made it comfortable for me as she ran the tests. I would definitely come back esp with the environment being so calm and nice.(>.<)
Always a pleasure

Realy nice personal doctors
This review is for Kristi Mendoza. In Apple Valley, California. License: AU 1439 I want to personally thank you for helping my 96 yr old dad. My brother and I and even my children have bought my dad so many hearing aids. And they failed. When my brother told me my dad had an appointment with the VA because of you I knew I had to thank you. Thank you so much for your kindness, for your patience and for your compassion and concern. We appreciate it so much. Now me and my kids can call my dad and talk to him on the phone. My brother said my dad smiled all the way home from the VA. That means more to us than anything. We want our dad to live a comfortable and happy life. He has done so much for this country where he can’t even hear. He truly deserves the best. Thank you so so much. Peace and blessings to you always. Your kindness will always keep you blessed.💕
I really was comforted by the way the clinician thoroughly explained, while instructing. E through the examen. Also they allowed me to eat up lots of Halloween candy
