Our Noise Measurement Services

Establishing if your workplace is 85 dB or more can be tricky. Different locations of you workplace can have different noise levels or perhaps your workplace isn't always 'noisy'.

Our noise exposure assessments include:


  • Sound mapping of your workplace to assess noise levels in different areas
  • ​Noise dosimetry of a worker to evaluate their total noise exposure averaged over the course of their shift
  • ​Our equipment meets the requirements of the Standards listed in section 219(3) of the OHS Code. 
  • ​Noise measurements summarized in an easy to understand report that meets Alberta OHS code requirements


Knowing how loud your workplace is and identifying worker's noise exposure is a key step in your noise conservation program

Do We Need Sound Mapping or Dosimetry?

If you are unsure if your workplace is loud enough to require noise measurement, read through the following questions. If you can answer yes to any of them then sound mapping and noise dosimetry may be the next step in your hearing conservation program.


  • Do workers in their workplace need to raise their voices to be heard in a conversation?
  • Do workers who work in noisy environments have ringing in their ears at the end of a shift?
  • Do workers find when they return home from work that they have to increase the volume on their car radio higher than they did when they went to work?


Having a noise measure report is an effective tool for assessing the adequacy of worker's hearing protection.

Hearing Conservation Program

Your workers are noise exposed so now you need a hearing conservation program.

Did You Know

"What needs to be done to protect workers depends on the level and type of noise at the workplace. Measuring sound levels identifies noise sources and those workers most likely to be exposed to noise exceeding the OELs (occupational exposure limits)."
