The preference of orchestra ensemble on sound absorption design in a concert stage

Abstract

Musicians in a symphony orchestra have to deal with more sound balance problems in a relatively compact stage when appropriate spacing between orchestra sections become unavailable. Under such circumstances, applying sound absorptive surfaces around the stage might benefit the condition of either hearing oneself or hearing each other. This paper explored the musicians’ preference on energy-restrained design with varying frequency characteristics, amount of coverage and location. Experiments took place with a well-reputed university orchestra at their rectangular concert hall in the routine practices. Room acoustic parameters were measured on site and in an 1/10 scale model, empty and occupied, to be compared with computer simulations.
