5.3 Classical sound level meter and averager integrator function

The sound level meter processes the signal sound pressure and simultaneously provides the following information :
LXY : the sound pressure level weighted temporally.
•
LXYmax and LXYmin : maximum and minimum values of the levels on measurement time.
•
Lupk : level of maximum peak of sound pressure on the measurement time.
•
LXeq : equivalent continuous level of acoustic pressure frequency weighted on measurement time.
•

5.3.1 Adjustment prior to measurement

1 – Select L-Leq mode : move the cursor with arrow keys to 1 and select 'L-Leq' with the scrolling knob key.
2 – Select the weighting frequency and the time weighting.
For each weighting frequency, the sound level meter proposes the measurement according to three time
weightings : Fast (F) – Slow (S) – Impulse (I). Possible choices are :
A frequency weighting : LAF – LAS – LAI
C frequency weighting : LCF – LCS – LCI
Z frequency weighting : LZF – LZS – LZI
Place the cursor with arrow key on the area 2 and select with scrolling knob identified measurement
criteria among the possibilities listed above.
3 – Select the weighting frequency of peak level of sound pressure : move the cursor with the arrows to 3
and select C or Z with the scrolling knob key.

5.3.2 Launch the measurement

In manual mode : directly press
limited to 24 hours.
In I/O mode : see chapter « Launching a measurement in I/O mode ».

5.3.3 During measurement

During measurement, three screens inform the current measurement. They are accessible through the
scrolling knob key.
E1 : it is the main screen that displays the instantaneous measurements.
LXY : the sound pressure level weighted temporally.
•
LXeq : equivalent continuous level of sound pressure frequency weighted on measurement time.
•
LUpk : level of maximum peak of sound pressure on the measurement time.
•
Duration of the measurement expressed in DD / HH: MM: SS
•
E2 : This screen contains results of values that will be stored in memory at the end of measurement :
LUpk : level of maximum peak of sound pressure on the measurement time.
•
LXYmax : maximum value of sound pressure level weighted temporally met since the beginning of
•
the measurement.
LXYmin : minimum value of sound pressure level weighted temporally met since the beginning of
•
the measurement.
LXeq : equivalent continuous level of acoustic pressure frequency weighted on measurement time.
•
LXE : level of exposure to sound frequency weighted
•
D : Measurement time expressed in DD / HH: MM: SS
•
% : percentage of saturation of the input stage.
