Comments on the importance of the early-to-reverberant sound-energy ratio, “Clarity,” in speech and music acoustics, related to use of sound-reflecting panels with attention to data in Dr. Leo L. Beranek’s three concert-hall books.

Introduction The first question this paper attempts to answer is “Has the ratio of early to reverberant sound energy largely replaced Reverberation Time as the primary measurable acoustical phenomenon for judging intelligibility of both music and speech?. This metric is also defined, acoustically, as Clarity (some also use Definition), and 80 milliseconds separates the two regions for music, 50 milliseconds for speech.1 These metrics are abbreviated as C80 and C50. Other authors find this metric of value for both evaluation...Read More
