Jack hammers are heavy duty, today we are discussing about how risks are reduced.
The nonprofit risk management center states that typical jackhammer noise emissions are around 130 decibels.
These jackhammers are muffled, or silenced to reduce the sound level of the tool, measured in decibels on an a-weighted scale (dBA). Pneumatic or electric jackhammers use an internal hammer to strike the back of the bit, known as the shank, which impacts the concrete or pavement. The hammer striking the bit is the main source of noise created by the tool, and mufflers or silencers help to absorb or block the sound at the source before it reaches the ears of workers.
