joyces, you ask how t-coils work with the TV. To get the TV to work with the telecoil, you need to connect your TV to a loop system. This means that you would need to run a wire around the area where you want to listen to the TV. The wire could be hidden in the baseboards or under carpet. Some people run a wire in the ceiling of the room below where the TV is at. It's not something that most people want to bother with. A loop amplifier would also be needed to connect the wire to the TV. Keep in mind that the closer we are to the TV speaker, the better we will understand. The telecoil brings the sound directly to the hearing aid. There are better ways to get the TV sound directly into your ears, but it depends on your hearing aids. For older aids that do not have Bluetooth, you would need a TV transmitter specific to your brand of hearing aids. Newer aids have Bluetooth capablility so you connect your TV to a Bluetooth transmitter. The signal would come directly to your ears. If your aids do not have Bluetooth, you can still connect your TV to a Bluetooth transmitter, but you would need a Bluetooth receiver. You still need to get the sound from the Bluetooth receiver to your ears. Bluetooth receivers may come with a headphone or a neckloop (or both). So, if your aids have telecoils, you would use a neckloop. This way, you don't have to remove your hearing aids PLUS you're taking advantage of the programming inside of the hearing aids. Without a telecoil, you would have to connect the Bluetooth receiver to headphones. You would probably have to remove your hearing aids to prevent the feedback that could occur with trying to use headphones with hearing aids.
