Abstract

Results from preliminary investigations studying graphical elicitation techniques suggest that a graphical assessment language, whereby listeners use their own non-verbal descriptors to depict spatial attributes of a reproduced sound, may be effective for demonstrating differences in perceived image skew and scene width. This paper investigates the use of a graphical assessment language for evaluating subjective differences in car audio systems with respect to their distortion of stereo images from sub-optimal listening locations. The study compares the image obtained from a surround processing system and conventional two channel stereo reproduction, analysing the graphical depictions obtained using conventional statistical methods. Source material for the investigation employs both time and amplitude variation to position instruments within the reproduced stereo scene.
