BACKGROUND NOISE LEVELS IN STUDIOS AND AUDITORIA

Abstract
The specification of background noise levels for auditoria must strike a balance between the lowest possible noise level from services and the need for some "masking" of extraneous sources. Studios are often designed to provide a suitable level of masking, using either aerodynamic or electronically-generated white noise. Data on noise levels in a large number of auditoria have been examined to determine whether a similar process is applicable to these. A wide range of seemingly arbitrary design criteria has been found.
