Abstract

The perceptions of ASW and LEV at different source-listener distances in a reverberant soundfield were investigated subjectively and objectively. 12 subjects graded the magnitudes of perceived ASW and LEV for trumpet and conga sounds that were convolved with binaural room impulse responses measured at 3m, 6m and 12m from the source. Both ASW and LEV were found to decrease significantly and almost linearly per doubling the distance. The distancedependent ASW was best predicted using objective measures called G E (early sound strength) while the LEV results were highly correlated with GL (late sound strength) and B/F ratio (Back/Front energy ratio of late sound). Such conventional measures as [1-IACCE], [1-IACCL] and LF did not agree with the perceived results. The findings of the current study are expected to provide psychoacoustic basis for controlling virtual front-back listening positions in a reproduced soundfield.
