The inductive coil of a hearing aid coil is a device used in a hearing aid to receive magnetic signals. When an alternating magnetic field exists in the surrounding environment, the hearing aid coil can sense this magnetic force and generate an electric current, which is then converted into sound by the receiver and transmitted to the human ear.
How does the inductor coil of a hearing aid coil work?
Hearing aid coil M stands for “microphone” and T stands for “inductor coil”.
When the hearing aid coil is in the M position, the coil does not work; when the hearing aid is in the T position, the coil recognizes the magnetic signals in the surrounding environment, amplifies them into electrical signals of the same size, and further converts them into sounds that can be recognized by the human ear.
The stronger the magnetic signal, the clearer and more realistic the sound you hear.
Which hearing aids have a hearing coil function?
Behind-the-ear hearing aids:Behind-the-ear hearing aids are large, easy to maneuver, and easy to install hearing aid coils.
Some customized hearing aids:Some ITEs and ITCs have the option of the inductive coil feature of hearing aid coils, while CICs generally do not have the inductive coil feature due to their small size.
Inductive Coil Usage of Hearing Aid Coils.
Manual switching
Manual switching is usually done in two ways.
1) Directly on the hearing aid body: Applicable to some hearing aids installed with “O, T, M”; this kind of hearing aids is usually manually adjusted analog hearing aids.
2) On/Off Program Button: For hearing aids with an inductive function program (the dispenser needs to set it in advance). These are usually computer-programmed hearing aids.Q-star Split Hearing Aids are the more advanced high-end hearing aids on the market today with the inductive function.
Automatic transfer
For some high-end hearing aids, as long as the inductive function is preset by the dispenser, the hearing aids can switch automatically when sensing the magnetic field environment without the need for the user to set it manually.
What can the inductive coil of the hearing aid coil do?
Function:Answer the phone
m:Microphone program
The microphone works normally and picks up the sound of the surrounding environment.
t:Induction phone program
