Described below are the different ways of displaying the acoustic functions for the
assessment of noise at workplace while measurement is taking place. If you change the kind
of display (screen) or the octave band selected (spectrum analyser screen), measurement
will continue uninterrupted. While measurement is in progress, however, you cannot switch
from one measurement mode to another.
Numerical screen
This screen shows, in real time, the next information:
•
Daily noise exposure level (L
EX,8h
).
•
Sound Exposure (E).
•
Noise dose (DOSE).
•
Equivalent continuous sound pressure level with frequency weighting A and C
corresponding to the measurement time (L
At
and L
Ct
).
•
Peak sound pressure level with frequency weighting C corresponding to the measurement
time (L
Cpeak
)
•
Criterion level (L
C
)
•
Measurement time (t)
By pressing the projected parameters are displayed.
The projected parameters determine the sound exposure if the measured level will keep
constant during the projection time.
The projected parameters allow evaluating the sound exposure for measurement times
shorter than the configured projection time t
p
.
