Barrie : Règlement no 2006-140, art. 4(5) — Noise By-law

Documentation The following represents the minimum information which shall be contained in a report of an investigation where the above procedure was used. (Adapted from CSA Z107.2-1973 Methods for the Measurement of Sound Pressure Levels.)

• (a) Acoustic Environment
• (i) Location and description of sound sources.
• (ii) A list of the types of extraneous noise sources which caused integration to be inhibited during measurement.
• (iii) Dimensioned sketch including photographs, if possible, of the location of the sound source and the point of reception. showing all buildings, trees, structures and any other sound reflective surfaces.
• (iv) Physical and topographical description of the ground surface.
• (v) Meteorological conditions prevailing at the time of the investigation including approximate local wind speed in km/h, wind direction, air temperature in C, approximate relative humidity and extent of cloud cover.
• (b) Instrumentation All the equipment used for making sound level measurements shall be listed, including:
• (i) type, model and serial number of Integrating Sound Level Meter;
• (ii) type, model and serial number of microphone;
• (iii) type, model and serial number of Acoustic Calibrator;
• (iv) extension cables and additional amplifier, if used. By-law 2006-140 33 Office Consolidation The Corporation of the City of Barrie Noise By-law
• (c) Acoustical Data The measurement details shall be described, including:
