After the noise mapping monitoring, a few employees are selected for personal noise monitoring. A dosimeter will be calibrated and fix at the waist of each employee. A microphone is clip on top of the employees' shirt shoulder.
The selected employees are briefed on the purpose of the dosimeter, for example, it is not a speech recording device. Instruction is also given to the employees not to remove the dosimeter unless absolutely necessary and not to cover the microphone with a coat or outer garment. To begin, all the dosimeters are switched on at the same time. At the end of the day, the readings and the time when the monitoring stopped is recorded and the dosimeters will be re calibrated.
