Frequently asked questions.

We are an independent audiology equipment calibration and repair company based in Modesto, California. The company was founded by Matt Brewer, who spent 15 years calibrating and servicing audiology equipment, including at E3 Diagnostics and Natus, before going independent. Matt leads our technical work, and service is performed on-site at your practice.

Yes. We are introducing ourselves to hearing and balance practices across the West. Our callers ask when your equipment is due for calibration so we can contact you once, shortly before that date, with a quote. They never ask for patient information or payment details.

You do not have to switch to keep us on file. Some practices keep us as a second option for when their usual provider is unavailable or a quote comes in high. If you send us your last calibration invoice or certificates, we will quote against it in writing so you can compare.

We are based in Modesto, California. Practices within about a four-hour drive, including Northern and Central California and the Reno area, are on our regular routes. We also serve Southern California, the rest of Nevada, Arizona, Utah, Idaho, Washington, Oregon, Colorado, Wyoming, Montana, and Hawaii on scheduled route weeks.

Outside our home region, we group practices in the same area onto one scheduled trip. Tell us your calibration due date and we will place you on the next route to your area.

Travel for a route week is shared across every office on that trip instead of billed to one. Your share is itemized on your quote before you approve anything.

It depends on how much equipment you have. A single audiometer typically takes about an hour. We schedule around your patients, and early-morning starts are available.

Yes. If your equipment or your offices are due in different months, we can calibrate some of it early so everything lands on one annual date. Practices with five or more locations receive 20% off calibration across every site.

Diagnostic and screening audiometers, tympanometers and middle-ear analyzers, OAE (otoacoustic emission) systems, real-ear and hearing aid analyzers, sound-field systems, ABR (auditory brainstem response) systems, and balance equipment including VNG systems, caloric irrigators, and CDP (computerized dynamic posturography). We also verify ambient noise levels in sound booths. One exception: Vivosonic ABR systems are not calibrated in-house. We send those out for calibration and handle the arrangements for you.

Annual calibration is the standard for audiometers and most related equipment. We calibrate to current ANSI specifications and keep you on a yearly schedule with a reminder before your due date.

Look for the calibration sticker on each device. It shows the date of the last calibration, the next due date, or both, along with the company that did the work. Your last calibration certificate has the same information. If you cannot find either, tell us what equipment you have and we will help you work it out.

Each calibration is documented for your records, and your equipment is labeled with its calibration date.

Often, yes. Send-in calibration and repair are available anywhere in the U.S., and equipment comes back with its calibration label and certificate. Two limits apply: sound-field speakers have to be calibrated in place in your booth, and some audiometer calibrations need an on-site visit. Contact us first and we will tell you what can ship.

It depends on what equipment you have and where you are, so we quote each practice individually and in writing.

Your last calibration certificates or a list of your equipment (make and model), your location, and your calibration due date. Email them to [email protected] or call us.

Yes. We diagnose and repair audiometers, tympanometers, and related equipment. In our service area, repairs can be handled on-site or in our shop. Anywhere else in the U.S., you can ship the equipment to us.

Yes. We take down, transport, and rebuild audiometric sound booths, including same-building moves and rebuilds with the door or window repositioned. We also install new and pre-owned booths.

Yes. We coordinate with biomedical or clinical engineering on scheduling, access, and records, and we complete whatever vendor setup your organization requires before the first visit.
