Earmolds for Hearing Aids

An earmold is a necessary component of any hearing aid

Quite simply, the earmold is the part that goes into your ear canal. It might be made of plastic, acrylic, or silicone. While some hearing aids use standardized ear pieces (domes) of a few different types and sizes, others require a custom earmold that fits your ear perfectly.

We will choose the right type of ear piece for you based on the shape of your ear canal, the amount your ear canals move with jaw movement and the severity of your hearing loss. Whatever the case may be, you can rest assured that Hearing Solutions of North Carolina will help you find what you need.

Standard Earmolds/Domes


Many BTE- and RIC-style hearing aids use standardized silicone ear pieces or domes. These are usually best for mild-to-moderately-severe hearing losses. If you still hear well in low frequencies, a vented/open dome may be suggested, which will allow sound to pass right through the dome from the outside. This can help provide a more natural sound, but isn’t sufficient for everyone.

RIC (Receiver-in-Canal) hearing aids place the speaker in the ear canal, which helps reduce feedback, or “whistling,” by increasing the distance between the microphone and the speaker. We work with domes that are either open, closed or power so we have many options for your particular hearing needs.  

Domes need to be replaced periodically. We will replace those for you during your maintenance checks or routine open clinic appointments. If your domes have worn out, or if you acquired your hearing aids elsewhere, we can get you properly fitted as long as your hearing aids are appropriate for your hearing needs.

Custom Earmolds

Custom earmolds require us to take an impression of your ear canal and outer ear. We will insert a protective cotton dam into your ear canal before injecting a two-part silicone material into your ear and ask you to open and close your mouth while it dries out. This ensures that your impression won’t be uncomfortable when you move your jaw while wearing your hearing aids. The process is completely painless and only takes about five minutes.

We send the impressions to a special lab where they use them to create a replica of your ear canals and outer ear structures. This replica then becomes the mold for your custom earmolds.

There are more than 10 general styles of custom earmolds, each for different needs or hearing aid types. We’ll talk with you about what types of hearing aids might best suit your needs and lifestyle, and they’ll examine your ears to determine which types of earmolds will work best for you. Some of the most common types include:
