By using overlays of loudspeaker polar plots (readily available in product literature) and both vertical and horizontal "polar plots" of a room, a loudspeaker array may be effectively designed. This method will not only show the effect of loudspeaker polar patterns in the room, but it will also show visually the interaction between loudspeaker polar pattern(s) and the inverse square law as overlays are manipulated in real time. Simple formulas for producing the room polar plots are presented, as well as computer programs in Basic and HP-41C.
