Time Weighted Average and Dose Calculator Calculates a worker's Time Weighted Average - TWA - noise exposure using the time spent and the sound level at each location. WebNoise Dose (D) It is the percentage of time a person is exposed to noise that is potentially damaging to hearing. Zero represents no exposure, and 100 represents complete exposure. At percentages over 100, the person has been exposed to noise levels that exceed their daily limit. Noise dose is calculated by dividing the actual time of exposure ...
