Hearing aid coils: How do hearing aid inductors work?
he magnetic signal generated when people wear hearing aids acts on the coil through a magnetic field, causing it to produce a magnetic force, which generates an electric current that is passed through the earpiece to the ear so that sound can be heard, and this is what the human ear hears, which is why we call this device a hearing aid coil or a hearing aid inductor.

Hearing aid coils: How do the inductors in hearing aids work?
The magnetic signal generated when people wear hearing aids acts on the coil through a magnetic field, causing it to produce a magnetic force, which generates an electric current that is passed through the earpiece to the ear so that sound can be heard, and this is what the human ear hears, which is why we call this device a hearing aid coil or a hearing aid inductor.
Hearing aid coils: How do hearing aid inductors work?
1. When you wear a normal hearing aid, as long as you put your ear on the inductor coil, the m-speed becomes a “microphone”; when you wear the t-speed, it becomes an “inductor coil”! When you hang the hearing aid on your ear and feel the m-speed coil with your ear, you will find that when you put your ear behind your ear, the sound you hear is bigger than when you put your ear in front of your ear.
2. Hearing aids have certain requirements on the strength of the body's magnetic field, if the body's magnetic field is too strong or too weak will affect the normal hearing function; conversely, it can not be used. The stronger the magnetic signal, the clearer and truer the sound heard. Therefore, in the process of use, according to different models of hearing aid coils to choose the appropriate size and shape of the back-of-the-ear hearing aid, in order to give full play to its induction coil function, to achieve the desired results.
Hearing aid coils: Which hearing aids have induction coils?
1. Behind-the-ear hearing aids: Behind-the-ear hearing aids are large in size, simple to operate and easy to install induction coils.
2. Behind-the-ear hearing aids: ITE and ITC have induction coils, CIC does not.
What is the difference between the two?
During the course of use, it is necessary to manually change some of the hearing aid coils to meet the needs of different types of hearing aids.
What is the difference between manual switching and automatic or manual switching?
1. Input the user's operation into the system, the system will automatically determine whether the user needs to replace the new hearing aid body, if yes, then execute the “o,t;m” command, otherwise, re-select a new hearing aid, until the completion of all the steps, and then compare the new hearing aid with the analog hearing aid.
2. Realize the guidance function of the software through the program switching button: When the user needs to replace different models of hearing aids, the professional testing technicians can adjust the different models of hearing aids needed according to their own needs, so as to achieve the purpose of computer programming of hearing aids. Its software part can be divided into two independent modules, i.e. preamplifier and post-amplification circuit. The preamplifier is mainly responsible for filtering the signal and filtering out the noise; the post-amplification circuit accomplishes the conversion work between input and output. Twinstar q-split hearing aids are more advanced hearing aids with high-end inductive function in the current market.
Automatic switching between some ordinary hearing aid coils and hearing aid induction coils;.
Answering a call is a headset machine with inductive coil (t-stop) m:Microphone program hearing aid microphone works normally and picks up the surrounding sound. If there is no signal transmission between the microphone and the earpiece during a call, it transmits the received information to the cell phone and displays it through the computer or other devices, thus realizing the phone call function.
