Overview

GAOTek Noise Dose Meter is a parameter used to quantify noise exposure measured in a period, during turns of % noise exposure relative to 90dBA for 8 hours., 100% DOSE = 90dBA for 8 hours This is known as the Criterion. Other criterion is available such as 100% DOSE = 85 dBA for 8 hours to meet legislation in different countries. If the person stayed in this environment for 4 hours, he would receive 50%DOSE. Also if the noise level was said 93 dBA, 3 dB higher, a 100% DOSE would be accumulated in only 4 hours, The above example is for a dose meter with 3dB Exchange Rate, where a 3dB increase in sound level corresponds to a doubling energy. A dose meter with 5dB Exchange Rate is also, available where the sound must increase by 5dB to double the dose as required to meet noise legislation in some countries.
