Early lateral reflections in some modern concert halls
Lothar Cremer · The Journal of the Acoustical Society of America · 1989
This article describes some of the means by which early lateral reflections (ELR) of sound have been provided in recent concert halls in which the author has been involved as acoustical consultant. Special problems are encountered nowadays. In earlier times, the disposition of audience seating in acoustical design was only a question of access: aisles, staircases, etc. Now, special account of the seating arrangement must be taken in order to provide suitable lateral sound reflections; and, particularly in large halls, this requires some departure from traditional seating plans.
