Logging Personal Noise Dose Meter SL-1256DOS Sound Level Tester

Description

Logging Personal Noise Dose Meter SL-1256DOS Sound Level Tester
DOSE 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 hours
This is known as the Criterion. Other criterion are available such as 100% DOSE = 85dBA 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 say 93dBA, 3dB 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.
