ABSTRACT

This study identified salient perceptual characteristics of Japanese listeners upon which they conceptualize multichannel-reproduced music with height ambiences and investigated influence of experimental variables including height-loudspeaker position, height signals, musical selection, and ambience level balance. Room ambiences were generated by convolving pre-captured room impulse responses at multiple locations with anechoic music recordings. Trained listeners were asked to evaluate various multichannel music stimuli with height ambiences and rank them. The results indicated that height-loudspeaker position and level balance differentiated reported listeners’ rank data. Furthermore, the elicited descriptors showed that listeners ranked high a specific multichannel music that was more enveloping and reverberant.
