1. GENERAL DESCRIPTION
Thanks for you’re selecting Personal Noise Dose Meter. To ensure that you can get
the most from it we recommend that you read the manual carefully before use.
The personal noise dose meter is test equipment to evaluate the noise condition of
working environment by measuring the accumulated noise exposure. With this test
data, company can ensure the related noise regulation is followed or decide whether
or not to apply certain noise reduction action to avoid the acoustic trauma and
noise-induced hearing loss occurs to the working personnel.

2. PRINCIPLE OF MEASURING ACCUMULATED NOISE EXPOSURE
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 dierent 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.
3. INTRODUCTION TO THE DOSE METER
The Noise Dose Meter measure the frequency weighted noise exposures and peak
sound levels simultaneously.
The meter has the following features:
Multiple simulated dosimeters (termed D1, D2 & D3)
Simple operation, including direct read-out of results
Ten built–in standard dose measurement setups:
OSHA-80, OSHA-90, MSHA-80, MSHA-90, DOD, ACGIH, ISO-85, ISO-90, NR-15
and NHO-01
