    Most workplace noises include a wide band of frequencies and are measured through the "A" filter in sound-level meters. The noise level is therefore expressed in decibels (dB) on the "A" scale, or dB(A). Duration of exposure is equally important. Duration is typically measured over a workday and accumulated through many years. The chart below
