Abstract

Concert hall acoustics has received important attention since the search described in Concert Halls and Opera Houses: Music, Acoustics and Architecture was published (Springer, 2004). An overview of those recent contributions that appear most useful to practicing acousticians is presented. A review of the Sabine and Eyring reverberation equations shows that if either the Sabine or the Eyring absorbing coefficients are known, the other is known automatically, provided the Sabine coefficients are allowed to exceed unity. In the context of the buildup of sound in a concert hall, the known parameters are discussed-sound energy density buildup, reverberation time T60, early sound, including initial time-delay gap (ITDG), apparent source width (ASW), listener envelopment (LEV), sound strength G, and various subjective considerations. Measurements in chamber music halls are summarized. A new formula for calculating LEV is presented.
