The Advantages of Open-Fit Hearing Aids
It is less visible than a traditional BTE hearing aid.
The open-fit does not close off the ear canal.
It eliminates the sensation of the wearer’s voice sounding like they are speaking into a barrel.
No longer is feedback an issue when using the telephone.
How Does an Open-Fit Hearing Aid Work?
A hearing aid has three basic parts: a microphone, amplifier, and
speaker. The hearing aid receives sound through a microphone, which
converts the sound waves to electrical signals and sends them to an
amplifier. The amplifier increases the power of the signals and
then sends them to the ear through a speaker.
In the case of an open-fit hearing aid, the amplified sound travels
through a small tube or small wire to a tiny dome or receiver in
the ear canal. The dome or receiver do not completely seal the ear
canal. The open space allows the sound can enter the ear canal
naturally, while still amplifying the sounds you have difficulty
hearing
