Spectral and spatial perceptions of comb-filtering for sound reinforcement applications.

Document Thumbnail

Most sound reinforcement systems consist of multiple loudspeakers systems arranged strategically to cover the entire audience area. This study investigates the spectral and spatial perceptions of interferences that can be experienced in the shared coverage area between two full-range loudspeakers. A listening test was conducted to determine the effect of lag source delay, relative level, and angular separation, on the perception of spectral coloration and spatial impressions (width, localization shift, image separation). The results show that spectral coloration is considerably reduced when sources are spatially separated, even with a small azimuth angle (10°). It was also found that coloration audibility depends on the interaction between the audio track and the delay introduced. Finally, the type of perceived spatial degradation depends mainly on the spatial separation and on the relative level of the source arriving later in time (lag source).
