What is Telecoil?

What is Telecoil?

Telecoil is like having noise cancelling headphones installed in your hearing aids. To activate these “virtual headphones” you need to 1) turn on your telecoil, normally a setting in your hearing aid, and 2) be inside a hearing loop (See types below). Telecoil (a tiny copper coil in your hearing aid) is usually free when you purchase your hearing aids.

Hearing Loop Types: There are many kinds of hearing loops: neck loops, portable counter loops, room loops, table loops, etc. You may or may not see the wired hearing loop. When I use telecoil at home to listen to my TV, cellphone, or laptop, I am using a neck loop. This 6 min video shows you how I do this: Click Here

It’s not exactly like a noise cancelling headphones because your hearing aids doesn’t really cancel any outside noise like a pair of noise cancelling headphones does. The external sounds still can go through the vent(s) in your dome and reach your ears and these external sounds don’t get cancelled out like they do in a pair of noise cancelling headphones. So if you still have good hearing in certain frequency range (like maybe the lower frequencies), you can still hear all the external sounds in tcoil mode just as loud as they are naturally.

In most HAs, you can choose to amplify on the tcoil content and not have the HA mics amplify the external sounds, or you can choose to amplify both the tcoil content AND still have the HA mics amplify the external sounds just as well so you can hear both at the same time. You can also adjust to have the HA mics amplify the external sounds but not as loud as normal so you’re aware of your surrounding but still be able to focus on the tcoil content more. But as mentioned above, even if you choose to not amplify the external sounds via the HA mics at all, the sound can still naturally enter into the vents. So it’s not like a pair of noise cancelling headphones unless you have a completely closed-off set of custom molds with no vent at all, and turn off the HA mics amplification.

Your tcoil can pick up not just content from a hearing loop, it can also pick up content from magnetic speakers as well when the speakers are applied next to your HAs, like the one in your telephone landline handset, or from a pair of over-the-ear or on-the-ear headphones (that has larger size magnetic speakers in them).

Not all HAs have tcoils in them. If you really want to have HAs with tcoil, you need to make sure that you choose a model that has this feature built-in right up front. It’s not an add-on that you can enable later. Sometimes the HA model with tcoil built-in may cost a little more than the same HA model without the tcoil option, but not always. So it’s not necessarily “free” to get. The tcoil model will usually be larger/bulkier than the equivalent non-tcoil model so there’s a trade-off, if not only in price, then also in size.

The ReSound Multimic is an accessory device that has a telecoil and can “add” that functionality to ReSound/Jabra aids.

A t.coil is a great. It is usually activated by Audoligest based on my experience. It uses a coil to tap into the hearing loop. I used them a lot. They are great and the quality of the voices is great. How it works with your hearing aids is dependent on how your Audoligest has set it up. I have molds that allow no outside noise in. What I hear is controlled by the microphones. When I use my t-coil it turns off the mics to make the voice clear. If you get to use them your in for a treat. Good luck.

You don’t always need to be “inside a loop” to use telecoil either. I’ve used it with magnets on my landline to hear with just HA’s.
