1 Introduction
The  noise dosimeter is a measuring instrument allowing measurement of noise exposure at workstation. Its
advanced features make easier the investigation to determine and reduce noise pollution:
➢frequenc anal sis b octave band for an optimal choice of protections
➢two-channel dosimeter for simultaneous measurement of exposures suffered b the ears
➢audio recording of noise sources on thresholds for a better identification
In accordance with international standards,  instrument calculates values usuall used to compare with exposure
regulator values.
Thanks to its memor ,  instrument stores measurement event timers which are then transferred to a computer and
processed with  software, supplied with the instrument.
 software supplied as option allows an anal sis more detailed as per NF EN ISO9612: 2009 standard.
In addition, this noise dosimeter has a classical sound level meter and anal zer integrating-averaging function for a 1st
estimation of the noise environment of the workstation.
1.1 Presentation
 comes in the shape of a little case with ergonomics forms. It can be easil positioned on the belt or in a cloth pocket
of people at their work station. the microphone at the end of extension is fixed thanks to a kit speciall designed to minimize
perturbations created b chocks or cloth frictions.
Measurements are stored in a microSD card memor of big capacit giving the whole an almost unlimited measurement
capacit .
With its graphic backlighted LCD screen, is also a classical sound level meter and an integrating-averaging anal zer
for a fast noise estimation at workstation.
During measurement, if necessar , it can advised people about levels through a two-coloured light.
1.2 Main features
Noise dosimeter and classical sound level meter and integrating-averaging anal zer with graphical backlighted LCD screen
with:
•microphone with extension t pe electret of diameter 3/8'' (9.52 mm) of little size allowing a reliable fixation
•2 measurement channel: side and  side (microphone and fixing kit for channel 2 as option)
•3 d namic ranges:
- in running mode, one measurement channel: 40-140 dB range
- in running mode, two measurement channels: 40-120 dB or 60-140 dB ranges
•Simultaneous measurement of Leq and LpK:
- Leq: with A and C weightings and b octave band filters from 63 Hz to 8 kHz
- LpK: with C or Z weightings
•Management of overange of peak pressure levels 135-137-140 dB
•Audio recording on thresholds of noise sources
•Dela ed and/or repetitive measurement start
•Ke board protection during measurement and against unwanted stops
•Active or inactive LCD screen, visual alarms
•Calculation and results in accordance with NF EN ISO9612: 2009 standard
•Storage capacit : 99 event timer of more 24h each
Li-Ion batter for a batter -life better than 28 hours (according measurement programming). All of the setting of  is
directl performed with the ke board or with the LDS300 software.

 is supplied with the software which allows to transfer easil data to a computer to:
•visualize measurement data globall or more detailed
•process areas of non-measurement (break, beginning and end of measurement,...)
•customize report for saving and printing
2 General points
2.1 Regulatory
The 2003/10/CE European Guideline makes mention of instructions regarding the exposure of workers to risks. The
regulator requirements define a control context of noise pollution in work place. From these controls, the obtained results
are compared with defined regulator action thresholds.
These thresholds are based on two parameters:
•the dail noise exposure level Lex,8 hours in dBA
•the LCpeak peak pressure level C-weighted
When thresholds are exceeded, actions have to be led.
The regulator specifies two action thresholds causing preventive actions:
•the lower exposure value –

These two thresholds are completed b a third one called TLV, threshold limit value , which should not be exceeded in an
case, with or without protection (PICB): !"

2.3 Measurement
It relies mainl on #!!$, #!!$ and #!!$ articles and completed b the decree of the %&'().
Measurement can be made according prescriptions of the NF EN ISO9612: 2009 standard.
The standard recommends three measurements wa s:
•b task
•b work or function
•b full da
This standard also specifies the measurement processing including the estimate of measurement uncertaint .
2.4 Noise exposure – Exposure points
This simplified wa is especiall adapted for workers whose position is constituted b several identifiable tasks. The
difficult to totalize levels dB does not allow a fast approach of the dail noise exposure, using this wa brings a ver
significant operating flexibilit .
It takes into account the noise exposure expressed in Pa²h of the several tasks that can be then add to get a global noise
exposure during the work da . From this, the determination Lex,8h dail exposure becomes easier b search in a dedicated
corresponding table. This table is available in the ED6035 document edited b the INRS.
 calculates the noise exposure and directl displa s on its screen the number of exposure points regarding the task
performed b the worker to his position.

6.2 Determination of the daily noise exposure
Available possibilities (see options list page 43) of  are based on the level of required investigation and on the
adopted measurement methodolog .
So it is possible to:
•Measure on one or two channels simultaneousl to determine the most exposed ear.
•Perform a a frequenc measurement with filters b octave bands from 63 Hz to 8 kHz on one or two channels. This
anal sis allows the optimum choice of personal protector against noise (PICB)
•Make from the channel 1 audio recorders on LAeq or LCpk levels exceeded for a better identification of noise
sources.
•Perform temporal settings:
➢Multiple starts and stops on a work station in connection with identified tasks or samples linked to the end-user
function.
➢Multiple starts and stops on a weekl work station.
C-/according programmings, some metrological features of the noise dosimeter are adjusted.

Calibrate the instrument
Before each measurement series, a calibration must be perform with an appropriate calibrator. A control will be also perform
at the end of the measurement. The interval between both calibrations should not differ from more 0.5 dB. If not, performed
measurements are questionable.
7.1 Free field coefficient
A sound reference source, calibrator or pistonphone, supplies a sound level pressure. During a measurement in free field,
phenomenons of diffraction due to microphone, housing and proximit of obstacles come to disrupt the measurement. This
disruption is minimized if the microphone is awa from the housing.
For , correction in free field linked to microphone is insignificant and close to. This induces b the proximit of
the microphone with the bod of the person who wears the microphone is ver complex and can not be expressed as free
field correction but more reasonabl as measurement uncertaint linked to microphone wearing.
So the ". free field correction reminded and unavailable on the screen is: ".
7.2 Modification of the value of the reference source
➢Select " pressing  ke from start screen.
The screen below appears.
The reference value pre-programmed during the manufacture of the instrument shows a priori that
we are using a calibrator of nominal value of 94 dB (1000 Hz). Other values that can be meet: 110
dB – 114 dB and 124 dB.
C-/the measuring is performed on the range 60-140 dB and in C-weighting, it is possible to use a
calibrator or a pistonphone delivering a frequenc of 250 Hz at a level of 124 dB without modification
of free field correction.

➢The cursor is on #.
➢Adjust the value dB b dB with K and $ke s.

7.3 Calibration
➢Insert into the calibrator the adapter ring  supplied with the instrument.
It has to come to a stop down of the calibrator housing.
➢Insert the microphone until the microphone comes to a stop down of the ring.
This move has to be done slowly and smoothly so as not to damage the microphone.
Prefer to put vertically the sound level meter and the microphone.
➢Begin the procedure of calibration of the instrument as specified in the calibrator user manual.
Note: during calibration, avoid hard environmental conditions: ambient noise, shocks given involuntarily.
7.3.1 Calibration of V1 channel
