A neckloop really has nothing to do with BlueTooth technology. It's a simple personal induction loop that allows a telecoil equipped hearing aid to connect with an audio device. That device can be a computer, an iPad, a portable radio, an FM receiver, an infrared receiver, or a cell phone that has an input jack, etc. It relates to the telecoil in the hearing aid by sending the magnetic signal from the audio device directly to the telecoil in the hearing aid. It's very simple technology. For example, I can be sitting in a noise bar or restaurant watching a sports event on TV with a group of people. Normally, I cannot hear anything in that environment. However, if I can get that same event on my small portable radio, I can listen to the radio broadcast while watching the TV and know what's happening. I can sit in a sports arena full of noise and do the same thing with my radio. We are die hard Green Bay Packer fans with seasons tickets, so this is something I do quite often. 🙂 Try a neckloop with your laptop computer while watching a YouTube video. It's magic!
