摘要

The principal features of an even sound field are large directivity and diffusive nature of the radiated field. Directivity pattern of stereo speakers was analyzed to determine the degree of coherence of the sound field in the room. Measurements of the sound field in close to a standard listening room conditions were conducted with the speakers placed in ITU-recommended and specially selected positions. The results showed that the radius of correlation corresponds to the size of the sweetspot. Relocating speakers in the room and taking into consideration the room environment influence can help to enlarge the listening zone within the room. These conclusions were confirmed by listening tests and recommendations on sound field correlation can be established.
