| ¦Funzioni di misura |
Misura simultanea dei parametri elencati, con selezione di costanti di tempo e ponderaiozni i nfrequenza |
| 1.Processi (canale principale) |
1) Instantaneous sound pressure level: Lp
2) Equivalent continuous sound pressure level: Leq
3) Sound exposure level: LE
4) Maximum sound pressure level: Lmax
5) Minimum sound pressure level: Lmin
6) Percentile sound levels: LN (1 to 99 %, 1 % Step: Minimum 5 values,calculated from Lp or Leq 1s) |
| 2.Processi (canale addizionale "sub")) |
1) Instantaneous sound pressure level: Lp |
| 3.Processi addizionali |
uno dei seguenti processi può essere addizionato ai precedenti:
1) C-weighted equivalent continuous sound level: LCeq
2) C-weighted peak sound level: LCpeak
3) Z-weighted peak sound level: LZpeak
4) The power average of the maximum level of each 5 second interval: LAtm5 |
|
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. |
| 4.Processi simultanei |
Misure parallele e data-logging di:
Logging with an interval of 100 ms: LXY
Logging with an interval of 1 s to 24 h (selectable in steps of 1 s):
LXeq and LAIeq, LXE, LXYmax and LAImax, LXYmin, LAN, LCpeak and LZpeak, LAtm5
X = Frequency weighting for A, C and Z
Y = Time weighting for F, S and ´ |
|
