AB  - On 22.2 multichannel reproduction, we sometimes listened to the sounds reproduced by a loudspeaker arrangement different from that on production, and we did not recognize the difference in spatial impression between them definitely. In this paper we discuss the effects of changing some of the loudspeaker positions from the reference on the spatial impressions in a 22.2 multichannel sound system. Subjective evaluation tests were carried out by altering the azimuthal and elevation angles from the reference in each condition. Experimental results showed that the listeners did not recognize the difference in spatial impression from the reference with some loudspeaker arrangements. On the basis of these results, the ranges keeping the equivalent quality of the spatial impressions to the reference are discussed when the reproduced material has the signals of all the channels of the 22.2 multichannel sound system.
