ABSTRACT:
Loudspeaker and stereophonic system employing hemicylindrical wave form generators, in which the vertical extent of the speaker includes and spans the levels of seated and erect standing listeners, approximating a floor to ceiling height. Two such speakers are placed in a room, directed toward each other and spaced from an end wall, with arc of sound emission of each such that the listener region receives direct sound and two first order reflections, from side and end walls, from each of the two speakers. The path lengths are shown different in length greater than the minimum separate-source discrimination time.
