Enlarging of the Listening Area by Increasing the Number of Loudspeakers
Future multichannel sound systems, especially suited to accompany HDTV and EDTV systems, should provide a stable localization of stereophonic images in a sufficient listening area. Arrangements with two, three, or four loudspeakers in the frontal area have been compared with respect to the directional stability of auditory events for different listening positions. It is concluded that four loudspeakers are necessary to obtain the same localization curves for all listening positions within an area as wide as a large HDTV screen. This is important for a directional congruence between visual and sound images.
