Acoustic Condition Factors
The term “acoustic condition factor” is used as a general term descriptive of the acoustic environs of a point in an enclosure. Relationships expressed as ratios are given for several quantities, such as “useful” and “harmful” sound, direct, and generally reflected sound energy and sound intensity. Curves are shown representing loci for partial antinodes produced by interference between direct and first as well as second reflections in a rectangular room in which the sound source is located symmetrically. Equations are given expressing the minimal distance between source of sound and microphone for the probable avoidance of recording absolute nodes.
