Monitoring of the Noise Emitted by Machine Tools in ...noise. For example lathes, milling and drilling machines produce noise up to 104 dB, metal cutting saws – up to 115 dB, and grinders – up to 134 dB. There are a couple of standards that substantially limit the permissible values of the noise emitted by machine tools. The permissible noise levels in work environments (NDN values), established for hearing protection, are specified by the ...
