An induction loop is a device that facilitates hearing for persons using cochlear implants and hearing aids with a built-in induction coil.

This solution is most commonly used in public buildings such as lecture theatres, conference rooms, auditoriums and museums. The use of an induction loop makes it possible to eliminate noise, reverberation and other unwanted sounds while improving speech understanding. 
 
The presence of an induction loop should be appropriately marked with an international sign. This is the symbol of the left ear against a white diagonal line with the letter T in the lower right on a blue background.
