  6. Operational & Production: Excavator – 7. Control of Noise and Operation Times



The operation of heavy equipment and machinery, especially at the processing area, causes increases in ambient noise levels within and at the vicinity of the Project site. Meanwhile, transportation activities along the transportation or navigation route lead to noise pollution to other nearby land users along the route. Higher noise levels cause nuisance and discomfort to nearby communities.


  • Minimise noise generated from project activities.
  • Protect the surrounding community from exposure to high noise levels.
