A lot of foundation works involved noisy activities, such as excavation/site formation, rock breaking and piling works. Typically, sound power levels of excavator/loader, bulldozer, excavator mounted breaker and piling machines can reach about 112 dB(A). Quieter equipment or methods are commercially available, which can significantly reduce the noise emission from the foundation works.
Noise reduction for some mitigation measures for reference.
Mitigation Measures
Use of acoustic enclosure for stationary plant can achieve a noise reduction up to 20dB(A) easily.
An effective way of reducing noise is to install a purpose-built barrier between the noisy equipment and the noise sensitive receiver.
