    Concrete Removal

Handheld or excavator mounted concrete breaker is a traditional mechanical equipment for concrete breaking and removal. Using such equipment will generate loud noise, with sound power levels generally range from 108 dB(A) to 122 dB(A). Nowadays, a number of commercially available quieter equipment or methods for concrete breaking or removal could be less noisy or could reduce the noise propagation. These include high pressure water jet system, handheld concrete crusher, medium duty breaker, blade saw, wire saw and noise enclosure.

Mitigation Measures

Noise enclosure for underground construction works

Use of acoustic enclosure for stationary plant can achieve a noise reduction up to 20dB(A) easily.

(Wilson Acoustic) Noise barrier

An effective way of reducing noise is to install a purpose-built barrier between the noisy equipment and the noise sensitive receiver.
