The noise level of 100 mm Angle Grinders when 'free running' for example can vary from 95 to 100 dB(A). This is dependent on factors such as bearing condition, gearbox wear and the age of the tool. Some of the better manufacturers can supply noise level data on the performance of the tool.
The noise energy levels considered to be excessive when noise levels exceed L Aeq, 8hr of 85 dB(A) and L C,peak of 140 dB(C). A general rule of thumb for detecting excessive noise levels is if you have to raise your voice when talking to someone 1 meter away. Some common noise levels include:
Measuring noise: Noise can be measured using a decibel meter. The name comes from Alexander Graham Bell and the unit of measurement is called- the bel. Usually the value in bels is multiplied by ten and the sound level is expressed in decibels (dB). More advanced devices are being used to determine the type of sound coming from impact pile hammers.

May 14, 2014 The noise levels of bench and pedestal grinders vary with the type of work being performed on the tool. Larger pieces of metal such as 50 mm angle iron will produce much more noise (typically 105 dB(A)) than touching up a drill bit (typically 84 dB(A)). The grade and diameter of the grindstone will also influence the noise level.

The higher the number in decibels, the louder the noise. The louder the noise, the greater the risk of hearing loss. Hearing loss can occur with regular exposure to noise levels of 110 decibels or more for periods longer than one minute. Not only can noise cause hearing loss, it can also cause tinnitus. So How loud is too loud?
