VANGUARD HEARING CENTER
earmolds are a component of behind the ear hearing aids. They are custom made to fit your ear exactly. Some fit in the bowl of your ear (the concha) and some fit in the canal.
Why fit matters
Ears come in all shapes and sizes. Just look at any group of 10 people and you will see no set of ears are the same. Even your right and left ear can be shaped differently. That’s why behind-the-ear hearing aids require an earmold that is made to fit each person’s ear exactly. If an earmold doesn’t fit properly, sound escapes the ear canal. The escaped sound is detected, picked up by the microphone, amplified and returned to the canal where it escapes again. With each iteration, the volume increases until you have a screeching or whining sound referred to as feedback. Feedback is a sign that your earmold doesn’t fit properly or isn’t inserted properly. Vanguard Hearing Centers specializes in medical grade ear molds in the metro Detroit area.

fit inside the ear canal and are made to be inconspicuous. They are made from an impression of the ear canal. These earmolds only work well for people with a fairly long ear canal. They are vented and tubed in the same manner as a full shell earmold.
