One dimensional reproduction of stereophonic sound is described in which at least two microphones sense the sounds produced by at least one soundgenerating point source. The sounds sensed by the microphones are reproduced through at least two transducers spaced a distance apart. The reproduced sounds comprise sets of incident travelling sound waves. Each set of incident travelling sound waves originates from a different transducer. The sets of incident travelling sound waves are transformed into corresponding sets of waves which travel toward one another along a sympathetically vibratable sound-receiving surface which is located between the transducers and the listener. The different sets of waves travelling along the sympathetically vibratable sound-receiving surface interfere with one another to produce separate and distinct standing waves in a direction perpendicular to the sympathetically vibratable sound-receiving surface. Each standing wave represents an individual soundgenerating point source being produced at locations along the sympathetically vibratable sound-receiving surface relative to the transducers, corresponding to the location of each sound-generating point source relative to the microphones.
