Reverberation Time, Other Metrics, and Underlying Goals
There has been much effort to measure and correlate quantitative acoustical parameters in existing halls to find some objective quantification of quality. The seminal texts of Leo Beranek and Vilhelm Lassen Jordan focused considerable effort on aggregating acoustical metrics for the purpose of characterizing the perfect concert hall. Their studies focus on reverberation time (RT), early decay time (EDT), clarity (C80), strength (G), room response (RR), lateral fraction (LF), and interaural cross correlation (IACC), among others. During the design of Suntory Hall, we also measured more than ten successful halls in Japan to try to quantify an ideal design using RT, EDT, C80, and RR. Ultimately, we found insufficient correlation with the subjective impression and the endeavor was refocused.
