This paper reports some of the influences of individual reflections on the timbre of reproduced sound. A single loudspeaker with frequency-independent directivity characteristics, positioned in a listening room of normal size with frequency-independent absorption coefficients of the room surfaces, has been simulated using an electroacoustic setup. The model included the direct sound, 17 individ...

Sound systems delivering enhanced Spatial reproduction compared with conventional two-channel stereo demand appropriate subjective testing techniques to assess their performance. Sound quality assessment methods of the past 30 years have been mainly concerned with attributes other than spatial, concentrating primarily on timbral and distortion issueswhen assessingthe qualitiesof loudspeakersor ...
