Interior/ partial interior renovation works at the existing building would cause noise impact to the residents at neighbouring buildings or units. Concrete/ brickworks breaking and tiles/paint removal using handheld breakers are common noisy renovation works. Sound power levels of traditional handheld breakers can generally reach 108 dB(A). Use of some smaller mechanical equipment such as mini-breaker or innovative method such as high pressure water jet for tiles/ paint removal would generate less noise during renovation works.
Sound pressure levels of traditional and quieter equipment/ method for reference.
Quieter Construction Equipment
Compared to traditional hammer drills for demolition, it greatly reduces the structure-borne noise impact.
Compared to traditional hammer drills, mini air hammer greatly reduces the transmission of structure-borne noise.
Compared to traditional drilling tool, the use of diamond coring tool can reduce the transmission of structure-borne noise by about 4dB(A).
Compared to traditional hammer drills, the battery-driven fastening tool greatly reduces the noise impact without compromising on the productivity.
The application of a wall chaser achieves a significant structure-born noise reduction of around 19dB(A) as compared with that of using a traditional percussive hand-held breaker.
Electrically-powered mini-breaker with pneumatic hammering mechanism can be used for medium-duty chiseling on masonry and concrete.
