A study on multi-channel sound reproduction relating spatial impression with a music source

摘要

Loudspeaker layout of Multi-channel sound reproduction was experimented using a music source convoluted with directional room responses of virtual sound field. Based on subjective estimation, arrangement of loudspeakers suitable for exact reproduction of spatial impression was studied. The results showed that, under the condition that the loudspeakers were arranged at equal interval of angle, it is necessary to use more than 8 loudspeakers and to put one of them in the frontal direction.
