Perception of spatial distribution of wide sound sources
Abstract
The perception of the spatial distribution of sound sources composed from multiple loudspeakers emitting continuous signal is studied in this article by conducting two listening tests. The tests were performed in an anechoic chamber using 15 loudspeakers evenly distributed in frontal horizontal directions equidistant from the listener. In the rst test, various sound source distributions such as sound sources with varying widths and wide sound sources with gaps in the distribution were used to emit uncorrelated pink noise. The subjects were asked to report which loudspeakers emit sound according to their own perception. In the second test, noise signals with different bandwidths as well as sinusoids were used as stimuli. These were presented using loudspeaker combinations with different number of loudspeakers spaced evenly on the frontal horizontal plane. The results of both tests are discussed.
