Starkey Custom Hearing Aids: Building Behind the Scenes


As part of new hire orientation, some Starkey Hearing Technologies employees receive the opportunity to have ear impressions taken, as well as build his or her own pair of custom hearing aids. During our training, we took a close look at custom order forms, hearing aid models, battery sizes, vent styles and wax protection options. We toured the manufacturing area and spent the rest of the day building our hearing aids.

Starkey Hearing Technologies prides itself on its personalized approach and as a result is the industry’s leader in custom products. While walking through the production department, it was clear to see the attentiveness and care of each technician working to ensure that every hearing aid that moves through the manufacturing process will be the best device for that particular patient.

We hope you enjoy this behind-the-scenes look at a just a few of the many steps that go into each custom product from Starkey Hearing Technologies!



These impressions of my ears were used to create shells for completely-in-canal (CIC) hearing aids. CICs are typically for those with mild to moderately severe hearing loss and are virtually undetectable when worn.







We received our shells already printed from the electronic scans of our impressions. The faceplates had also been pre-wired for us with the receiver.






The receivers were tested for sound quality at each step in the process.





Typically, hearing aid shells are laser-engraved with the serial number and a variety of other options – the patient’s name, contact information or hearing aid brand. I chose to do my first initial and last name.





After the engraving, wireless (or right/left) symbols are added to the inside of the shell. For CICs and invisible hearing aids, a removal handle is added. Then, the shell is adhered to the faceplate.








The receiver, microphone and battery doors are sealed and the excess receiver tube is trimmed down. The faceplate piece is trimmed and all material is buffed until smooth.









All done! Next, the hearing aids go through a series of testing before they are sent to the hearing care professional’s office where they will be custom programmed for each patient’s individual hearing loss.

Going through this process gave me some excellent insight into how much precision goes into the production of custom hearing aids. I can confidently say that an enormous amount of detail and work goes into ensuring our hearing aid wearers receive the most innovative technology and a custom, comfortable fit!
