NOISE SURVEYS
Identify noise levels by completing a noise survey
Occupational noise surveys allow for the measurement of noise levels in the workplace to ensure compliance with the Occupational Health and Safety Act O.Reg. 381/15.
In Ontario, average noise levels across an 8-hour period should be below 85 dBA. When noise levels exceed this limit, action must be taken by the employer. This action may include:
Elimination of noise source
Engineering controls
Administrative controls
Hearing protective devices
We conduct our noise surveys using a Type 1 Sound Level Meter, measured in octave bands. This strategy is far beyond the recommended minimum standard for noise measurements. A more thorough analysis of noise levels of specific frequencies greatly improves the understanding of noise in the workplace, which can lead to a more appropriate selection of hearing protective devices.
Using an octave band measurement, we are able to obtain frequency-specific noise data. On the right, we see most of the noise is around 2-4 kHz.
Frequency-specific noise data can then be used to select the most appropriate hearing protection. This method of measuring noise and selecting hearing protection can provide the maximum accuracy.
