Let’s talk tech, but in simple terms. A telecoil (or t-coil) is a small copper wire built into some hearing aids. It lets your hearing aids connect directly to certain sound systems, like a built-in Bluetooth for public places.
Think of it like this: instead of your hearing aids picking up all the surrounding noise, the telecoil connects directly to a sound source, like a microphone in a theater or a speaker at an airport gate.
Not all hearing aids come with a telecoil, so it’s always worth checking!
