For assessing acoustic risk, the following could be used  

FIGURE 5.25 Types of machine tools located in the hall (a) grinder, (b) driller, (c) lathe, 

In compliance with Directive No. 42/2006/EC, the acoustic prediction concerning the intended position of machinery is important, or in case workplaces are not defined or impossible to be defined, the noise levels determined by weighted filter 

Note Measuring equipment used and data measured Integrated phonometer 2240 type. Accuracy level 1, produced by Bruel and Kjaer.
