In a moving vehicle, communication is frequently difficult due to the high noise levels. This is especially the case when the front passengers want to communicate with the rear passengers. For an improved understanding, those engaged in conversation often lean over towards each other and speak more loudly. With longer conversations, this is stressful and tiring. With the In-Car -Communication (ICC) system from paragon, the understanding and communication between the vehicle’s passengers is significantly improved. Firstly, the spoken words of the active person are recorded by microphone (e.g., a belt microphone), before then being played back over the speakers (e.g. head rest and door speakers).
