Acoustical measurements on a home stereo installation

This paper describes a two-way 500-cycle crossover loudspeaker system using the infinite baffle principle. A 300-cubic-foot volume is used. Two identical systems are spaced 15 feet apart for stereo reproduction. A description of the living-room architectural acoustics is included. There are no parallel walls or surfaces, and the splay of the side walls is a minimum of one inch per foot. Reverberation decay charts are provided for different frequencies to indicate the effect of the splayed walls. Sine wave and warble tone curves are shown and sine wave single-frequency levels are plotted for the width and length of the room.
