Hearing aids are complex machines. They pick up noise with a microphone, amplify it with an amplifier, and play it through a speaker. But telecoil hearing aids pick up sounds in a different, and difficult to understand, way. So, here’s our step by step guide on how a hearing aid loop captures and transmits sounds.
No hearing aid loop would be possible without a microphone. The microphone is what picks up the noise that you want to hear. It’s the same as any other microphone that you might encounter.
This microphone is placed close to the sound source, whatever it is: a person speaking behind a counter or a lectern, a speaker system, or something else besides. It’s pointed directly at the sound source, so as to dismiss other noises but pick up what you want to hear clearly.
The precise kind of microphone can differ. It may be a handheld one, one that sits on a desk, or one that is attached to clothing. What matters is that it transmits what it picks up to the audio loop driver.
The Audio Loop Driver
Once the sound has been picked up, it needs to be delivered to you. The audio loop driver is a vital part in this process. The audio loop driver is like a big amplifier. The microphone is wired into it, like it would be wired into a regular amp.
The only difference is that instead of delivering the sound to a speaker, it sends the sound it picks up to a copper wire loop. This loop goes around the audience, somewhere that you can’t see it, and is responsible for getting the sound to your hearing aid.
Like an amplifier, the audio loop driver can control the sound that comes through it. They often have automatic gain control, which keeps the volume at a steady level. They can also be turned on and off, and even used in groups.
Copper Wire Hearing Loop
As stated above, the audio loop driver is attached to a large metal loop. This metal loop sits in a ring around the audience. It can be quite big, like the size of a cinema or a big auditorium.
You’re likely wondering what exactly this loop does, and how it gets any sound to your hearing aid. Well, this coil produces an electromagnetic field which everyone sits inside. This entirely harmless field is modulated, i.e. it changes, depending on what sound the audio loop driver picks up on. This means that the magnetic field’s signals can be picked up, ‘interpreted’ and translated back into sound.
The Hearing Aid
There’s one last part that the system would fail without, and that’s your telecoil hearing aid. This system doesn’t help people with regular hearing aids, because regular hearing aids don’t pick up on magnetic signals. You need a special hearing aid that does, called a telecoil hearing aid. These hearing aids can be bought either online or through a specialist.
The telecoil hearing aid has its own tiny ‘hearing loop’ inside it. This loop is coiled up around a wire, which makes it perfect for receiving signals like those produced in the magnetic field around you.
When your hearing aid picks up on one of these signals, it plays the sound back to you like it would with any other sound. But the quality is much better, and you should be able to hear clearer and louder than you would otherwise. That’s what makes hearing aid loops such a popular choice for venues around the country.
Why Buy a Telecoil Hearing Aid?
The main reason you’ll want one is if you need a hearing aid! Telecoil hearing aids work exactly as regular hearing aids do. They pick up sounds using a tiny microphone and play them back to you louder and clearer. The only difference is that they also have a tiny receiver that they use to pick up on hearing loop signals.
You can buy telecoil hearing aids from anywhere that you might find regular hearing aids. They’re common, and aren’t much more expensive than a regular hearing aid.
Another reason you might want to buy one is the great variety of places that use hearing aid loops. Ask around, and you might find hearing aid loops in places like:
- The cinema
- Your local church
- The bank
- A local music venue or auditorium
The quality of sound you hear will be improved at each of these places. If you regularly go out of a weekend to go to church or listen to music, then your quality of life would definitely be improved with a telecoil hearing aid.
Come to Sandia Hearing Aid Center
Whatever hearing related equipment or advice you need, contact Sandia Hearing Aid Center. We have been serving the Colorado Springs area for years, and our expert hearing aid consultants are ready to assist with any enquiry you might have.

It all starts with a brief hearing test. Even if you’re sure your hearing has diminished, it’s important to check and make sure what the issue is: it could be something like wax. Also, only one of your ears may be affected.
The results of the test are clear straight away: there’s no waiting around. Your audiologist will then advise you on the best course of action, whether that’s buying a hearing aid or not. If you’re interested in a telecoil hearing aid, they can tell you all about how they work, why you might want one, and how much one will cost.
And that’s it! There’s nothing more to it. So, what are you waiting for? Come on down to King Hearing Aids or Sandia Hearing Aid Center today, and see how we can help you!
