1 Dosimetry
053-669, Rev A eg5
1: Introduction
Dosimetry
Measuring noise in the workplace is
an important element of hearing
conservation programs and noise
reduction programs. With a noise
dosimeter, you can assess and
determine a worker’s daily exposure
to noise levels. This information
can be used to ensure compliance
with regulatory bodies or to ensure
if hearing conservation programs
are needed.
To get you started quickly with the
Edge, the first chapter is dedicated
to introducing basic noise dosimetry
terms and information. The
subsequent chapters will guide you
through setting up the dosimeter,
running studies, and assessing your
results with easy to follow steps
and illustrations. Figure 1-1: Sample

Noise dosimeter
What is a noise dosimeter and how does it compute measurements?
Essentially, a noise dosimeter is composed of the following: a microphone
with a preamplifier, a weighted network, fast or slow response time, an
internal clock, calculator, and memory to store logged data.
The illustration below is a diagram of a basic noise dosimeter. The microphone
will, when exposed to a sound pressure, generate an electrical signal. The
signal will be increased by a preamplifier, and then is regulated to an
applicable level by the range control (dB range). The signal then goes through
a filter set or weighting system. The next circuit is the response circuit, which
controls the dampening of the readout. The response choices are typically
Slow or Fast. Finally, the results will display on the dosimeter screen.
For computation and storage, the clock tracks the sampling time. Dosimeters
record how long sound levels exceeded a set upper limit. The calculator
computes an L-avg, a dose, a TWA, and other data. The memory stores all
times, calculations, and measurements.
For post-processing, QSP-II is used to view and analyze your measurement
results with the option to view and/or print reports.
