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.
High pressure water jetting is a concrete removal technique mainly to remove deteriorated concrete, and tiles. Different from jackhammers and drill hammers, high pressure water jetting does not produce structural impact, and hence, less structure borne noise transmission, less damage to the building structure and less noise emission. It can be applied inside inhabited building.
