Simultaneous measurement of the following items, with selected time weighting and frequency weighting:
Processing (main ch)
Instantaneous sound pressure level:
Lp
Equivalent continuous sound pressure level: Leq
Maximum sound pressure level:
Lmax
Minimum sound pressure level:
Lmin
Percentile sound levels:
LN (0.1 to 99.9%, 0.1-increment steps, max. 5 values)
Processing (sub ch)
Instantaneous sound pressure level:
Lp
In addition to main processing items, one of the following can be selected for simultaneous processing:
C-weighted equivalent continuous sound level: LCeq
C-weighted peak sound level:
LCpeak
Z-weighted peak sound level:
LZpeak
I-time-weighted equivalent continuous sound level: LAIeq*2
Maximum I-time-weighted equivalent continuous sound level: LAImax*2
The power average of the maximum level of each 5 second interval: LAtm5 (0.1 to 99.9%, 0.1-increment steps, max. 5 values)
The frequency weighting for the additional processing synchronizes with the frequency weighting of the sub-channel, so when the sub-channel has A-weighting,
LAtm5 can be selected.
When C-weighting (Z-weighting) is selected, the additional processing LCeq and
LCpeak (LZpeak) are selectable.
A-weighting: 25 dB to 138 dB
C-weighting: 33 dB to 138 dB
Z-weighting: 38 dB to 138 dB
C-weighting peak sound level: 55 dB to 141 dB
Z-weighting peak sound level: 60 dB to 141 dB
