Induction/hearing loop systems
amplifier for buses


Primary benefits:

A unique system developed by Intervox to improve the accessibility of service in buses for the hearing-impaired public.

This innovative system integrates with all bus audio systems (announcers/microphones/ radio/DVD) and transmits them at a dedicated frequency (independent and free from background noise) directly to the hearing aids of the passengers.

In addition, the system also is capable of transmitting personal frontal conversation with the driver (when boarding the bus and purchasing a ticket).
