3D-sound in car compartments based on loudspeaker reproduction using crosstalk cancellation
One way to enhance driving safety is to use signal sounds. Driver attention may further be improved by placing sounds in a 3D-space, using binaural synthesis. For correct loudspeaker reproduction of binaural signals, crosstalk between the channels needs to be cancelled out. In this study, a crosstalk cancellation algorithm was developed and tested. The algorithm was applied in a car compartment, and three loudspeaker positions was compared. A listening test was performed to determine the subjects' ability to correctly localise sounds. It was shown that loudspeakers placed behind the listener correctly reproduced sound sources in the back hemisphere. Loudspeakers located in front and above the listener gave a high number of front/back confusions for all angles.
