Principle of Measuring Accumulated Noise ExposureDOSE is a parameter used to quantify noise exposure measured in a period, during turns of % noise exposure relative to 90dBA for 8 hours.i.e. 100% DOSE = 90dBA for 8 hoursThis is known as the Criterion. Other criterion are available such as 100% DOSE ..
