Occupational Noise Surveys

Our occupational noise surveys quantify worker exposure to sound across your operations using calibrated instrumentation and methods aligned with CSA Z107.56 (Measurement of noise exposure) and applicable provincial and federal occupational health and safety regulations. We help you identify who is at risk, where the noise is coming from, and what controls — engineering, administrative, or hearing protection — will bring exposures within compliant limits and support a defensible hearing conservation program.

Key Benefits

•Accurate measurement of personal noise exposure (Lex,8h) and area sound levels (Leq)
•Identification of equipment, tasks, and zones driving exposure
•Prioritized control recommendations following the hierarchy of controls
•Documentation supporting compliance with provincial OHS noise regulations and the Canada Labour Code
•A defensible baseline for hearing conservation programs and audiometric testing

Our Process

1Pre-survey walkthrough and scope confirmation
2Calibrated personal dosimetry and area sound level monitoring, with octave-band analysis where required
3Data analysis against applicable jurisdictional exposure limits (typically 85 dBA Lex,8h)
4Written report with findings, noise contour mapping where applicable, and prioritized recommendations
5Follow-up support for hearing conservation program development and control implementation
