Noise generated in cars is transmitted through airborne and structure borne transfer paths into the cabin. Changes in the locations of either the source or the receiver will alter the transfer path. Binaural transfer functions of airborne sound were measured in order to determine how changes in locations of either the source or the receiver affect them. The measurements were performed on a car where the binaural transfer functions for various positions of the source and the receiver were measured directly. In addition, examples of automotive sounds were reproduced through a loudspeaker in the source position and recorded with an artificial head in the receiver position. Changes in perceived sound quality caused by displacements of the source and the receiver position was studied through a listening test and compared to the changes in binaural transfer functions. The results show that the binaural transfer functions are affected by small displacements in location for either the source or the receiver. This variability causes changes in sound quality and must be considered in order to draw correct conclusions from transfer function measurements and sound quality analyses based on artificial head recordings.
