Hearing Loop System - Ledatel

Passenger-friendly communication support for hard of hearing persons.
Communication without barriers.

Induction loops are used to support hard of hearing persons traveling by public transport. This solution lets them receive clear audio signals from the Passenger Information System without any external interference, significantly improving the travel experience.

The signal from a sound source, in this case the Passenger Information System, is sent to a loop amplifier installed in a vehicle, at a station or at a stop. The amplifier then generates a current which flows in a closed circuit creating an alternating magnetic field which is finally converted into sounds by a hearing aid coil.

Public transport: trains, trams, busses and taxis
Public transport infrastructure: stations, platforms, stops, airports
Passenger service points: ticket offices, passenger information, rest areas
Intercoms, SOS points
Lecture halls
Cinemas and theaters
