ABSTRACT:
An embodiment and/or method to improve communication in a vehicle. Voice signals of the occupants of a vehicle may be picked up on an individual basis via separately arranged microphones. The individually picked-up voice signals may then be amplified separately for each occupant in an input stage and filtered for purposes of minimizing interference levels and for frequency adaptation. The signals may be subjected in a process stage to a signal processing that may be specific to each output channel, in the form of a delay correction and a level differentiation. And, via an adaptation stage having a level adaptation, the signals may then be distributed to likewise separately assigned loudspeakers, in accordance with the spatial conditions of the vehicle and the desired loudness level. The embodiment and/or method may be effectively used in passenger cars, larger vehicles including multimedia buses and trucks, ships, trains and airplanes/airborne spaces.
