Daily Personal Noise Exposure : LEP,d is the averagedA-weighted
noise exposure level for a nominal 8-hour working day and is for assessing the noise exposure of a employee during a working day. It is also known as LEX,8h.
Noise Dose Meter : Sound Exposure Meter also known as Noise Dosemeter and Noise Dosimeter.
Noise Dose per Hour : DOHR - shows the dose exposure over each hour.
Noise Dosimeter : a pocket sized instrument designed to be worn during all or part of the day as a personal monitor in order to check an operator's personal exposure to workplace noise - see Sound Exposure meter.
NProjDose : Projected Dose : uses the current
Noise Dose value, logged during the present measurement, to be projected forward to give the predicted 8 hour period, assuming the sound levels for the remaining time stays the same.
Threshold Level : most regulations specify that for the measurement of noise at work, the sound levels below a certain limit (the threshold) should be disregarded. A Noise Dose Meter, therefore only sums up the contributions from the levels above the threshold and uses these values to calculate the
Noise Dose parameters.
