A number of practical techniques can be used as part of normal day-to-day operational and maintenance procedures that will achieve significant reductions in the noise emitted, will cost very little to implement and can provide worthwhile savings in energy. Possible solutions include:
- Tighten loose guards and panels
- Use anti-vibration mounts and flexible couplings
- Planned maintenance with a program for regular lubrication for both oil and grease
- Elimination of unnecessary compressed air and steam links and science air exhausts
- Keep machinery properly adjusted to the manufacturer’s instructions
- Use damped or rubber lined containers for catching components
- Switch off plant not in use, especially fans
- Use rubber or plastic bushes in linkages and use plastic gears
- Rest equipment and design-in noise control
- Specify noise emission levels in orders
- Check the condition and performances of any installed noise control equipment
- Keep doors and windows closed during off work hours
- If loading is necessary, carry it out during the day
- When maneuvering a vehicle, stop the engine once the vehicle is in place
- Check the condition and performance of any noise control equipment and silencers
- Turn exhaust outlets from fans away from nearby houses
- Carry out spot checks of noise levels at perimeter fences, both during working days and at other times
