This paper discusses the design of reverberation chambers for use in sound recording studios. Such factors as the optimal ratio for height-width-length for various room sizes, the variation of reverberation time with room volume for enclosure having such preferred dimensions, and the effect of wall construction using materials with various sound absorption coefficients are considered and illustrated graphically. Equations for estimating noise infiltration and the effect of small openings are given. It is indicated that the minimum dimensions required to achieve satisfactory results for adding reverberation in recorded speech and music should be of the order of (symbol)/2 at the lowest frequency of interest, and that the minimum room volume should exceed 1000 cubic feet. A summary of the factors which must be considered in the construction of such chambers is offered in conclusion.
