Richard, it's not quite that clean cut to noise assess machinery or plant equipment in work areas.

The figures that you are looking at would probably be available from manufacturers' documentation, but this does not take into regard the use of other equipment in close proximity to that being assessed.

You are asking here for generic best practice noise assessment figures in isolation not in real work use circumstances.

These circumstances have to be taken into account when transient noise is detected alongside the actual machine or tool being tested for noise emissions.
