New room acoustics measurement software
J. S. Bradley, R. E. Halliwell · The Journal of the Acoustical Society of America · 1986
Auditorium acoustics research has now developed to the point where there is quite general agreement on the subjective importance of four types of newer measures. These are: (1) decay times; (2) early/late ratios and other measures of clarity; (3) the overall strength or sound level; and (4) lateral energy fractions. In the past such measurements have been made by researchers using various complicated arrangements. The new software runs on an IBM PC compatible computer and controls a Norwegian Electronics two-channel analyzer, so that these newer auditorium acoustical measurements can be much more conveniently obtained. The design of the system and results by this and other methods will be discussed.
