What is a hearing aid with at coil?

Magnetic Resonance Imaging. ANTENNAS or COILS You don’t KNOW what

These hearing aids have a coil that transforms that magnetic field back into sound through the user’s hearing aid, isolated from reverberations and ambient noise. The result is that the user receives a clear, perfectly intelligible sound with an adequate volume.

In this field, Liftel has created the LTB100, an inductive loop created specifically for the elevator world. With the LTB100, the user receives the message properly amplified, free of background noise and reverberations, by placing the hearing aid in the “T” position through his or her prosthesis.

The LTB100 is connected in parallel to the loudspeaker of the LIFTCOM device, which can be installed on the car ceiling or on the control panel and is equipped with three potentiometers to adjust the input volume, output power and a filter to eliminate distortions in installations with ferromagnetic materials.

The telecoil is an induction coil that is integrated in hearing aids and cochlear implants. It performs the function of a receiver in hearing aids, since it captures the electromagnetic field and transforms it into sound.

Any electromagnetic field induces an electric current. When the “T” position is activated in the hearing aid, the coil detects the electromagnetic field and transforms it into sound through the hearing aids and implants, thus eliminating annoying environmental noise.

A cochlear implant is a technical aid to restore hearing in cases of profound bilateral deafness. Like the hearing aid, it can activate the coil to detect the electromagnetic field.

Well we have good news, if you don’t know what the “telecoil” or “magnetic loop” is, we are going to talk about it in this post. We already gave some hints about accessible rooms for people with hearing loss in the post “Disobeying certain urban legends about audiology (I)” but today we dive into the subject.

Something very important to keep in mind is that when you buy a hearing aid you have to explain to your audiologist that you need to have the telecoil incorporated because it conditions the type of hearing aid you have to choose.


One of the most common situations that will occur when you start using hearing instruments is that of being able to communicate through telephone conversations. Although your hearing center will give you first-hand information on how to deal with this situation, here are some recommendations.

The first thing to know is how to position the telephone receiver in relation to the hearing aid. The ideal is to keep the telephone earpiece close to the microphone input of the hearing aid but always maintaining a certain distance to avoid annoying whistling. If we rest the earphone on the hearing aid it will produce those annoying interferences to which we are accustomed.

Telecoils can be used as long as the telephones are compatible to be able to elevate the voices that are received by the telephone. If you have a behind-the-ear hearing aid with a telecoil, you should keep the telephone behind your ear and close to the hearing aid, always having the telecoil activated. If the hearing aid is an in-the-ear hearing aid with telecoil, the telephone should be kept close to the telephone.
