Using a 4-inch or 125 mm grinder instead of a 9-inch or 228 mm grinder can reduce noise levels by 6 to 10 dB. use grinders with quieter motors. Isolation mounts reduce vibrations caused by grinders and can reduce noise by 2 to 4 dB. clamp work pieces as close as possible to where grinding is happening. Move employees who are not using grinders further away from noisy grinding processes.
We all know working in the building and construction industry can be a noisy job! With the typical noise of an angle grinder being reminiscent of attending a live rock concert, this can have negative consequences when carrying out building and construction projects, particularly in noise sensitive areas. As well as having a potential negative effect on others in noise sensitive areas, the noise from using construction tools can also increase the risk of Noise Induced Hearing Loss to the user. A research study by the Building Trades National Medical Screening Program found that the construction industry saw the second highest number of workers exposed to noise hazards, with nearly 80% of welders suffering from hearing loss and 47% or roofers experiencing NIHL. The National Institute for Occupational Safety and Health found that a 25-year old carpenter is likely to have the ears of 50-year old person who has not been exposed to noise.

How loud is a cut off wheel?
The decibel level of an angle grinder wheel ranges from 120-140 decibels, depending on the type. Angle grinders are used in a variety of different woodworking and metalworking situations to be able to grind away material on surfaces and items with ease.
