1. A method for providing audio in a vehicle, said method comprising the steps of:
providing a plurality of audio channels comprising a first audio channel and a second audio channel;
processing, by an audio signal processing system, each audio channel of said plurality of audio channels to establish a principal signal and an accommodating signal for each audio channel of said plurality of audio channels;
supplying said principal signal of said first audio channel to a forward loudspeaker of a first loudspeaker pair and supplying said accommodating signal of said first audio channel to a backward loudspeaker of said first loudspeaker pair to generate a forward directional radiation pattern based on said first audio channel and having a forward propagation direction, wherein said first loudspeaker pair is installed in a dashboard in said vehicle and said first loudspeaker pair is disposed among a first occupant location, a second occupant location, and a sound reflection surface in said vehicle, and said first occupant position and said second occupant position are located on the left and right sides of said vehicle respectively;
supplying said principal signal of said second audio channel to said backward loudspeaker of said first loudspeaker pair and supplying said accommodating signal of said second audio channel to said forward loudspeaker of said first loudspeaker pair to generate a backward directional radiation pattern based on said second audio channel and having a backward propagation direction, wherein said backward loudspeaker of said first loudspeaker pair faces backward and faces to said second occupant position and said forward loudspeaker of said first loudspeaker pair faces forward and faces to said sound reflection surface in said vehicle, and forward is opposite to backward, wherein said forward loudspeaker of said first loudspeaker pair receives both said principal signal of said first audio channel and said accommodating signal of said second audio channel, and said backward loudspeaker of said first loudspeaker pair receives both said accommodating signal of said first audio channel and said principal signal of said second audio channel; and
guiding said forward directional radiation pattern to a first occupant location via said sound reflection surface in said vehicle, wherein and said backward directional radiation pattern directly arrives to said second occupant location in said vehicle.
