The obligation
PCBUs should assess noise over a typical shift, measuring each task's noise level and how long workers are exposed during it.
A hand-held integrating sound level meter usually gives the most useful information for choosing controls; noise dosimeters may suit highly mobile workers or hard-to-access positions. Measurements should capture the combined noise of all tools, machines and processes plus background plant noise, with each source also measured separately. One representative assessment can cover a group of workers exposed to identical noise sources with likely equal exposure.
