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.
Noise reduction for some mitigation measures for reference.
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.
