Construction sites aren't exactly an area for peace and quiet. While loud noise is unavoidable, you can keep it within a reasonable volume. Here are a few construction noise control measures to keep in mind. This keeps complaints on the low end while also protecting crew members from future hearing loss.
Prolonged exposure to noise above 90 dBA can cause hearing loss. If you have to shout to talk to someone at an arm's length distance, then noise levels are dangerously high.
Use a decibel meter to determine the noise volume. Set up noise perimeter zones where the volume exceeds 90 dBA. You should designate all hard-hat areas as noise perimeter zones. Only staff working at the moment should be inside this area, and hearing protection should be mandatory.
- Install mufflers/silencers on breakers and hoe packs. Mufflers can reduce volume by about 16 dBA.
- Replace worn or loose parts on equipment that cause excessive vibration
- Lubricate machine parts to minimize friction
These measures are your responsibility when operating company-owned equipment. If using rented equipment, the rental company will usually handle the maintenance, but you still need to take precautionary measures.
You can also lower noise levels by incorporating new workplace practices. Examples include:
- Turning off equipment instead of letting it idle
- Not dropping items from a scaffold
- Installing noise absorbing material over enclosures. Mineral wool is one low-cost material that you can place over screens and fences.
- When feasible, use electric-powered equipment over diesel-powered ones. The former is generally quieter.
