When a register recovered from the memory is displayed on the screen the sound level
meter uses the L
C
criterion level and the t
p
projection time configured. This feature allows
evaluations for a register according to the L
C
criterion level and the t
p
projection time set on
the sound level meter.
1/1 Spectrum analyser screen
This screen shows, in real time, the next information:
•
Graph of the equivalent continuous sound pressure level with the integration time
corresponding to the measurement time ( bars) in real time for octave bands centred on
frequencies 63, 125, 250, 500, 1000, 2000, 4000 and 8000 Hz (with frequency weighting
A).
•
Numerical value of the equivalent continuous sound pressure level with the integration
time equal to the measurement time for the selected octave band ( bar) (with frequency
weighting A).
•
Central frequency of the selected octave band ( bar)
•
Overall equivalent continuous sound pressure level with the integration time corresponding
to the measurement time and with frequency weighting A.
•
Measurement time (t)
Graphic screen
This screen shows, in real time, the next information:
•
Time history (60 values) of the equivalent continuous sound pressure level with integration
time T and frequency weighting A.
•
Measurement time (t) and the elapsed integration time
