Demolition of building involves large amount of concrete breaking works. Traditional excavator mounted concrete breaker is one of the most popular equipment use for building demolition, and its sound power level can achieve about 122 dB(A). However, various quieter equipment for concrete breaking and demolition can also be found in the market.
Noise reduction for some mitigation meausres for reference.
Use of hydraulic concrete crusher is much quieter than using hydraulic breaker in demolition projects. The operation principle of hydraulic breaker is by percussive striking actions of its chisels, so that much more noise would be generated as compared with hydraulic crusher.
