Measurements of Stage Support on a 1/25 Scale Model of an Orchestra Platform

Abstract

Stage support values known as ST1 and ST2 were measured in different stage positions both in a 1/25 scale model and a computer model of an actual large concert hall stage. Tests on the scale model were made both with and without model musicians. For the measurement of ST, different distances to the first musician were tried; 2m clear space around the source and receiver looks optimal. The effect of the side wall profile of the stage was investigated; the profile in the actual hall was found to be unhelpful for support. Different positions were also tested for the orchestra on the large stage. The position with greatest acoustic support was found to be at the rear of the stage, not the position close to the front of the stage, which is commonly used.
