The discussion centers on compliance with US workplace sound regulations, specifically the maximum allowable sound intensity level of 90.0 dB. A factory with 32 identical machines producing a sound intensity of 92.0 dB must reduce the number of machines to meet this regulation. Calculations indicate that approximately 12 machines need to be removed to achieve compliance, although the provided answer options do not include this result. The correct approach involves logarithmic calculations to determine the relationship between sound intensity and the number of machines.
PREREQUISITESSafety officers, industrial engineers, factory managers, and anyone involved in workplace compliance with sound regulations will benefit from this discussion.
