Noise levels

Noise levels in forestry operations are often hazardous.

If measures put in place to reduce them  do not adequately reduce noise levels to below the prescribed standards, then hearing protection must be provided and worn at all times.

The standards prescribed in the regulations are an 8 hour average or equivalent level of 85dB. When noise levels exceed 85dB hearing protection must be used.

To achieve the desired level of noise reduction you must wear appropriate hearing protection.

Most forest machine noise levels are just below 85dB. Here is an example of a chart that shows different sound/noise levels for a range of activities.
