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.
Hand-held concrete crusher is used for concrete breaking and can be operated by one person. Less vibration and impulsive noise along the structure would be generated by hand-held concrete crusher than jackhammer. The sound pressure level at 7m from the working site is less than 70dB(A).
