Barrie By-law 2006-140, s. 3 — Technical Definitions “Ambient sound level” means Background sound level

Technical Definitions “Ambient sound level” means Background sound level;

“Background sound level” is the sound level that is present in the environment, produced by noise sources other than the source under impact assessment. Highly intrusive short duration noise caused by a source such as an aircraft fly-over or a train pass-by is excluded from the determination of the background sound level; Other technical terms are defined in Reference [1].
