INTRODUCTION
Entomed MedTech AB is, in cooperation with HLF in Norway, marketing a sound level dose meter de-
signed to allow for an easy and efficient noise level screening and monitoring, as a complement to
traditional methods for sound level dose calculations and measurements.
It is designed for continuous use, thus adding the time perspec-
tive to the measurements, but yet most easy to use. Put it on
the wall at a suitable location; connect the enclosed mains
adaptor to the nearest mains outlet – Ready to use!
All sound level dose meters are shipped with the alarm level
factory pre-settings as follows:
 Red indicates sound levels of 70 dBA or more.
 Yellow indicates sound levels of 67 dBA or more.
 Green indicates its currently monitoring the sound level.
These settings and the indicator lamps intensity might easily be
altered using the rotary switch at the bottom.
The following sound level dose meter models are available:
 Lydia U sound level indicator (not available on all mar-
kets)
 Lydia X sound level dose meter
 SA40 sound level dose meter
The SoundReport reporting program, enclosed in the shipment, adds additional monitoring and report-
ing features to the level dose meter, such as parameter settings and real time monitoring and visuali-
zation of the sound level.
For Lydia X and SA40, with their unique design in automatically storing the sound level measurements
in their measurement data memories, the SoundReport program provides a complete and easy to op-
erate system for the screening and monitoring of sound levels and sound level doses, to be analysed,
printed and documented into reports – fully in accordance to the occupational health and safety legis-
lation and its noise level regulations.
LYDIA U although basically being a sound level indicator, but yet designed to allow for being upgraded
with additional software and a measurement data memory – in order to provide exactly the same func-
tionality as the Lydia X type sound level dose meter.
The sound level dose meter is shipped with pre-settings,
ready to be used
Put it on the wall at a suitable location and connect the enclosed mains adaptor to the nearest mains
outlet. The green light indicates that it has started monitoring the sound level and according to the fac-
tory pre-settings, the yellow light indicates a sound level of 67 dBA or more and the red light indicates
70 dBA or more.
Positioning the sound level dose meter on a wall
It is important that the sound level dose meter is positioned in such a way that the measured sound
levels are relevant to the sound levels of the room. When positioned on a wall, the recommended hor-
izontal distance to the closest corner is 30-45% of the length of the wall. I.e. if the wall is 3.0 m, the
recommended distance is 0.9 to 1.35 m from the corner.
Regarding the vertical position, it’s recommended to be related to the level of the heads of the people
occupying the room, adults or children, standing upright, sitting down on chairs or directly on the floor.

Setting of the alarm levels and the indicator light intensity
The sound level dose meter has a rotary switch at the bottom - providing
for manual settings
The pre-set values for the alarm levels and for the indi-
cator light intensity might easily become altered by the
use of the rotary switch at the bottom.
(Please Note. The switch should always be set back into position
”0” when operating the sound level dose meter).
Sound level, manual setting of alarm levels for yellow and red indicators
Manual setting of the alarm levels for the yellow and the red indicator lights.
Disconnect it from the mains, then turn the rotary switch into position ”D”. Recon-
nect it to the mains and all three indicators are switched on.
Turn the rotary switch into the posi-
tion of the desired alarm level (in dB)
in accordance to the table to the left.
When the desired setting has been selected, all indicators provide one flash, then wait until the green
indicator has provided one flash. Disconnect it from the mains; turn the rotary switch back into position
“0” and the selected alarm levels have been set.
The sound level dose meter, with the new alarm level settings, is ready for use and to be connected to
the mains.
Manual setting of the indicator light intensity
The indicator light intensity could be altered from maximum down to minimum or even switched off.
The factory pre-setting, when shipped, is the second to maximum setting, corresponding to the rotary
switch position ”E”.
To alter this setting, disconnect it from the mains, turn the rotary switch into position ”F”.
Reconnect it to the mains and all three indicators are switched on at maximum intensity.
For maximum intensity, disconnect it from the mains; turn the rotary switch back into position “0”.
For less intensity, turn the rotary switch step by step counter clockwise until the desired intensity has
been achieved. Position ”F” represents the maximum and position ”1” the minimum intensity.
Disconnect it from the mains; turn the rotary switch back into position “0” and the selected indicator
light level has been set.
The sound level dose meter, with the desired light intensity, is ready for use and to be connected to
the mains.
Please Note! In position ”0” all indicators are switched off – an important feature for the Lydia X and
Entomed SA40 models thus allowing for the monitoring of the sound levels “unaffected” of individual
behaviour.

In order to simplify the registration procedure, it is possible to
customize the preferred default information. However, its still
possible to accept/alter this information when saving the indi-
vidual file to the PC (please refer to tab ”Measurement”).
Setting the time interval/point of times for the calculation of LEX
The Lydia X and SA 40 measurement data files contain continuous information about the sound level
24 h/day throughout the entire measurement period. In order to calculate the sound exposure level,
LEX, alt. the daily sound dose exposure, LEX,8h, please enter the relevant points of time and the days
of the week for the period to be calculated and reported.
The programme provides the calculation possibilities of two
separate time periods/work day (i.e. work day divided with brake
for lunch). This, in combination with the selection of work-
days/week, provides the means for simplified automatic calcula-
tions and report procedures in cases of shift work, 24-hour duty
services, 7 days/week alt. where calculations for parts of the
work day are preferred.
Please note, the calculation settings do not affect the measurement data file contents, thus
providing the possibilities for repetitive and/or alternative calculations and hard copy print-outs for indi-
vidual of a work team etc. or exposure levels for a specific period of time of the day.

”Time weighting”-setting and that this setting is reported on all hard copy print-outs as well.
(Refer to tab ”Measuring” for the
measurement data file settings and
tab ”Device” for the down-loading
preferred settings into the SA 40).
Please note, the measurements are
all reported in dBA for weighting
filter A, and accordingly reported in
dBC for weighting filter C settings.
Zooming in – zooming out resp. repositioning of the diagram
Please refer to page ”Day view” for detailed information regarding these functions.
Documentation – hard copy print-outs/export of measurement data
”Print” –button initiates a hard copy print-out on selected printer.
Please Note! Hard copy print-outs will have the same diagram size/position as displayed on screen.

Documentation – hard copy print-outs of reports
Reporting sound pressure level measurements in hard copy print-outs
All the reports are designed to fulfil the applicable demands (incl. traceability) as identified in interna-
tionally recognized standards related to the Lydia X/SA 40 Sound Level Dose Meter (i.e. sound level
meters, sound level measurement, quality management, calibration equipment and procedures etc.).
Generating the hard copy print-outs
Select desired tab ”Day view”, ”Time view” resp. "Total view” depending of the information to be
printed. Check the diagram zoom, click the ”Print”-button thus generating the hard copy print-out on
selected printer (alt. generates a PDF-file in cases a PDF-writer program is being installed).
Please Note! Hard copy print-outs will have the same diagram size/position as displayed on screen.
Export of measurement data
Select desired tab ”Day view”, ”Time view” resp. "Total view” depending of the information to be ex-
ported, click the ”Export”-–button thus generating the information into the format of a ”text file”. A pop-
up window “Save as” appears, enter a desired file name - select the folder for saving the file.
Measurement uncertainty – automatically reported calculation
There are a number of factors, which all together will have an in-
fluence on both the accuracy of the measurement as well as the
Uncertainty of Measurement (UM) of the measured sound/noise
pressure levels. An indication of the size of such an Uncertainty of Measurement (UM), calculated in
accordance to the principles established by GUM101, is automatically provided to every, in tab ”Time
view” reported sound pressure level measurement.

Uploading measured values from the Lydia X and the SA 40
Select ”Measurement” and then select the desired folder, of the tree structure, for the storing of the
measured data file. Click ”Load” to initiate the upload. Enter the information related to the measured
data file, check/adjust ”Date” resp. ”Time” and click ”Save” to store the measured data file and its re-
lated information to the PC hard drive.
When completed, the information stored is displayed in the information area (to the right) and a popup
window appears, asking whether the measured data file in the data memory should be erased ”Yes”
or ”No”.
Documentation – hard copy print outs/export of measurement data
Select ”Total view”; ”Day view” or ”Time view” depending of the information (measured data, dia-
gram or table) to be documented.
”Print” –button initiates a hard copy print out on selected printer.
”Export”-–button generates a ”text file” to become imported into other programmes.
Measurement data memory check
The memory status is verified as follows:
 A number of flashes of the yellow indicator followed by 3 flashes of the green indicator = the
measurement data memory is erased – the entire memory capacity is available for this meas-
urement and the measurement has actually started and is continuing until the memory is com-
pletely filled.
 Only 3 flashes by the green indicator = there are already measurement data stored in the
memory, the current measurement has just been initiated and will continue until the memory is
completely filled.
Please Note! When the memory is completely filled, the indicators continue to indicate in accord-
ance to the settings, but the measurement data storage into the memory is stopped in order pre-
vent data losses from the time when the measurement was initiated.
