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
measurement display

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.

Dosimetry
Range of sound
053-669, Rev A eg5
3
Range of sound
Sound pressure is measured in decibels, or tenths of a Bel. Sound
pressure level is indicated as dB SPL. Since the human ear can detect
sounds with an extensive range of amplitude, a decibel scale is used to
simplify the measurement results. For example, the ratio between the
threshold of hearing and threshold of pain in the human ear if
measured in true energy is 10,000,000 times! The same range using
the dB scale is 0 - 140 dB referenced to 20 µPa (Micropascals).
The quietest sound that humans can hear has an amplitude of
approximately 0 dB. Prolonged exposure to sound pressure levels
exceeding 85 dB can cause permanent damage to the ear. Sound
levels in excess of 130 dB are more than the human ear can safely
withstand and can result in serious pain and permanent damage.
What do the standards say?
Many organizations have studied and analyzed the effects of high
sound exposure on hearing. As a result, standards were developed to
regulate personal noise exposure. In the United States, the
Occupational Safety and Health Administration (OSHA), the Mine and
Safety and Health Administration (MSHA), and the American
Conference of Governmental Industrial Hygienists (ACGIH) have all
created regulations and limitations on total permissible noise exposure.
International standards are specified by the health and safety
regulations such as the European Union (EU) Directive 2003/10/EC.
Additionally, the International Electrotechnical Commission (IEC) IEC-
61252 has specific guidelines and regulations to monitor noise in the
workplace.

Applications of the Edge
053-669, Rev A eg5
4
Applications of the Edge
The Edge has a cable-free, mounted microphone that converts sound
pressure into an electrical signal. This signal is conditioned, monitored,
and integrated over time in order to provide a host of automatically
calculated values that can be used in occupational and environmental
noise assessments. Programmable parameters permit the Edge to
serve many applications. The Edge can be used in the following
applications:
As a personal noise dosimeter - Used to measure a worker's
daily exposure to noise levels. This information can be used to
ensure compliance with OSHA, MSHA, ACGIH, IEC, or your own
customized parameter settings to determine if your workers are
over-exposed to noise.
As a time-history monitor- Used to provide a worker's minute-
by-minute noise exposure levels. This data can help you identify
major contributors to the average daily noise exposure.
As a survey monitor
1. Throughout a plant/facility – used to oversee noise levels
throughout an entire facility. You can identify machines and
equipment which produce harmful noise levels.
2. Specific areas in a plant/facility- used to identify key areas
as “noisy” and implement noise control options. Employees
may be exposed to unacceptable noise levels.
As a peak dosimeter- Used to detect the highest level of
instantaneous sound pressure.
Time history: manufacturing
Peak Measurement:121.20 dB

eg5 Overview
The “eg5” model is an intrinsically safe instrument featuring simultaneous C
and A weighted measurements. The instrument will also calculate C-A. The
“eg5” model features two virtual dosimeters with data logging. Once the
parameters are set and saved in the dosimeter, you can monitor two different
dosimeters by a single press of the Enter button. This will toggle you between
the two dosimeters.
Figure 1-3: Parameter setup screen for eg5
NOTE on Edge 5-bay charger: If you are using a 5-bay charger, you
may have various models docked at once as indicated in Figure 1-3. The
models selectable in the 5-bay charger section is dependent on if you selected
the eg3 & eg4 or eg5 models. QSP-II will display a green circle with a
checkmark indicating a docked, powered on Edge with the serial name. QSP-II
will also display a checkbox in front of applicable models that are selectable for
setup parameters. (See Customizing set-up parameters” on page 26 more
details.)
Virtual dosimeters
You can monitor and log noise studies by enabling two different parameter
settings in one dosimeter, also referred to as “virtual dosimeters”. For
instance, you may want to set one dosimeter to log using the OSHA HC
(Occupational Safety and Health Administration - Hearing Conversation)
parameters and also monitor noise with the OSHA PEL (Occupational Safety
and Health Administration – Permissible Exposure Level) settings.
A few scenarios of virtual dosimeters include:
Industrial noise control, hearing conservation compliance , work site
assessments, personal noise verification, and military applications.

Checking the equipment
If your instrument was sent to you in a storage case, you will want to
remove all the packaging and acquaint yourself with the following
equipment so you can quickly get started with your noise studies.
✍ NOTE: Depending on the accessories you selected, the dosimeter may
have the following components. For the docking stations, you will either
have an EdgeDock1 or an EdgeDock5. (For more information on

QuestSuite Professional II software
QuestSuite Professional II (QSP-II) is a software application designed by
Quest Technologies that runs under the Windows operating system. You
can use QSP-II for a variety of functions related to the Edge dosimeter and
with many other Quest instruments. QSP-II has the ability to customize
your set-up parameters, display data, manipulate data, and create reports.
Loading
To load QSP-II software , follow the instructions on the back of the CD.
It will automatically load the drivers for the EdgeDock1 and/or EdgeDock5.
If loading from Quest Technologies Internet site, please follow the
directions online. (http://questtechnologies.com/)
Docking station functionality
Depending on the kit you purchased, you may have an EdgeDock1 and/or an
EdgeDock5. Both are designed similarly with the same LED indicators. The
main difference with the EdgeDock5 is that it has five bays for docking,
charging, and/or managing the dosimeters. If desired, the EdgeDock5 will
charge all docked instruments at one time.
The docking station serves a
dual-purpose role :
(1) It is used to charge the battery on the dosimeter(s).
(2) It is used to communicate between the software (QSP-II) and the
dosimeter (i.e., import, export settings and measurement files).
