Interaction of Perceived Distance and Depth Comparing Audio Playback System and Musical Context
AES Convention 138 · Paper 9280 · May 2015
Abstract
The effects of the audio playback system and musical context were studied focusing on the perceived distance and the spatial depth. The experiments were carried out using a method of magnitude estimation comparing how near or far the combination of perceived visual and auditory event is, between two performers where one is fixed and another is moved back and forward. In the first experiment, the participants compared the difference among seven distances. In the second experiment, the participants compared direct-to-reverberant ratio (DR ratio) and differences of sound pressure level (SPL) among several musical context such as melody and accompaniment, precedence and chase of almost identical phrases, and non musical stimulus (pulse sound). The results showed that the perceived distance and depth were affected by the existence of image, DR ratio, and SPL. Furthermore these effects are different from musical context and playback system such as the existence of center, rear, and height loudspeakers.
