Abstract

The effect of frequency bandwidth limitation and stereo base width on listeners’ preference for loudspeaker reproduction of music and movie sound was studied. Various combinations of high and low frequency band limitation were considered for near-field monophonic and stereophonic loudspeaker reproduction. Two speaker configurations with a reduced stereo base width representative of mobile multimedia systems were also included in this experiment to investigate the perceived effect of a stereo enhancement algorithm. The results of this study indicate that naïve listeners consider low-frequency content to be more important than high-frequency content and stereophony in their preference judgments. For cases where the optimal stereo reproduction was preferred to the monophonic and reduced stereo base setups, a significant improvement in preference was found with the stereo enhancement systems.
