To recreate a “concert hall in a telephone booth,” a smaller volume is delineated within the original environment. The surfaces of this sound-transparent volume are covered with microphones, all having a directional pattern facing outwards from the volume. The sampled space is reproduced with an array of loudspeakers corresponding to the microphones but with their directional pattern pointed inwards. Since the listeners can move freely within the recreated environment, some basic limitations associated with binaural listening are removed. Experiments were made with a twelve channel system. Studies included (a) room effects, (b) anechoic listening, (c) localization accuracy, (d) relay loss, (e) use of a single low-frequency source, (f} sound distribution, (g) number and location of sources, (h) comparison with direct listening, and (i) comparison with earphone binaural listening. © 1968, Acoustical Society of America.
