Portable Induction Information System for the Hearing Impaired "Maestro 4.0" - Enhance Communication

The Maestro 4.0 portable information and induction system for the hearing impaired (hereinafter referred to as the portable system) is designed to transmit audio information to persons with impaired hearing function in case of increased ambient noise level or in the presence of an obstacle between interlocutors, in public places, in public service areas (near information desks, cash desks). Listening to audio information by a person with impaired hearing function is performed through a hearing aid in the "T" telecoil mode. The portable system converts an acoustic signal (operator's speech) or an electrical audio signal (streaming audio signal from devices) into an electromagnetic signal, which is received by the hearing aid's telecoil.
