For example: An angle grinder that produces 110 dB, is not operated for 8 hours a day, but normally only a couple of minutes of time spread over the day, which can add up to, say 1 hour actively operating it. The time in between might be spent with changing work pieces, welding, reading drawings, communication etc.
