What is a telecoil?
A telecoil or “t-coil” is a program on the hearing aid that helps you hear on the telephone and connects to FM or audio loops. You can use your telecoil at any event or religious services where the room is “looped.” Simply set your hearing aids to the telecoil program. When the speaker talks into the microphone, the sound will be picked up by the “loop” and go directly to your hearing aid(s). It will turn off the background noise and allow you to hear the speaker.
How does it work?
Telecoil works by turning off the regular microphone on your hearing aid and only picking up the sounds from the phone, FM, or audio loops. You can put the hearing aid on the telecoil program by pressing the button on the back of your hearing aid. You may need to move the phone around a bit until you find the best sound.
When your hearing aid is on the telecoil program, the microphone is not on, so you will not hear anything until you have a working telephone next to your ear or in a “looped” room.
Are there problems with a telecoil?
You may hear interference while on the telecoil program. There may be a “buzzing sound” from the devices. Fluorescent lighting, televisions, and computer screens may make this buzzing louder. Try to move away from these devices when using the telecoil.
Another problem that can occur is that the telephone is not “hearing aid compatible”. For example, some cordless phones do not work well with telecoil, as there can be too much interference. You will have to use a hearing aid compatible phone.
Telecoil can be a tremendous help, but you will need to get accustomed to them in the beginning. We encourage you to visit your local “Hearing Loss Association of America” chapter for more ideas and resources.
After you use your hearing aid compatible phone or leave a “looped” room, you have to press the button on the back of your hearing aid to return it to the regular microphone setting.
