Abstract

Alberta Infrastructure is involved in a project to develop a system and procedure for monitoring and controlling the amplified performances. The intent was to provide Sound System Operators with a clear indicator of their sound levels so they could voluntarily take action to limit it. A warning light is triggered to indicate that the levels are approaching the limit and a horn is triggered to indicate that the limit has been exceeded. The locations of the measurement stations were chosen to be unobtrusive and intercept the line of site from the stage to the affected condominiums/apartments, northeast and northwest of the stage. Investigations detected existing background noise levels in the northeast community ranging from 47 dB(A) to 56 dB(A). The implementation of sound source localization logic into the software program resulted in a 98% reduction in false triggers at measuring station #2.
