    "abstract": "The criteria for realistic reproduction of sound are discussed, showing how directional sound-collecting and dispersing systems may be employed to give results comparable with those of an ideal binaural system of reproduction. The use of a directional sound-collecting system, together with a directional sound-dispersing system, establishes: a “center of gravity” of the action; an illusion of depth or perspective; an acoustical or reverberation characteristic compatible with the picture; a large ratio of direct to reflected sound in the theater, emphasizing the acoustical properties of the theater; in musical reproduction, a correct balance and reverberation characteristic by the use of the two parameters.",
