Problem: Noise
A carpenter is involved in a significant construction job; part of their work is to prefabricate a series of wooden panels that will form part of the ceiling at a new concert hall. The job involves cutting engineered wood panels to the prescribed size using a table saw. As the duration of the cut depends on the size of the panel; an LAeq measurement is taken over several minutes to capture the loading and unloading of panels and a series of cuts. This measurement results in an LAeq value of 91 dB(A). Comment on the representativeness of this measurement and determine the carpenter's equivalent 8 hour exposure if they perform the task for 4.5 hours, and have no other significant noise exposure.
