Complaint Investigation of Stationary Sources The One Hour Equivalent Sound Level

• (Leq) of road traffic may be measured or calculated. Measurements of the One Hour Equivalent Sound Level
• (Leq) of road traffic shall be carried out using instrumentation described in Reference [2], following procedures for the measurement of varying sound described in Reference [3]. The results of the road traffic Leq measurements must not be affected by the sound due to other noise sources; the measurements should be performed when the stationary source under impact assessment is not operating. The time interval between the road traffic Leq measurements and the measurement of the sound level produced by the stationary source under impact assessment should be minimized as much as possible. Preferably, the two measurements should be carried out within one hour of each other. The calculation of the One Hour Equivalent Sound Level
• (Leq) of road traffic shall be based on the traffic flows observed on the contributing road(s), from which traffic noise is audible at the point of reception, within one hour of the period

when the sound from the stationary source is measured. The calculation procedure is described in Reference [11]. By-law 2006-140 59 Office Consolidation The Corporation of the City of Barrie Noise By-law
