Measurement functions |
Simultaneous measurement of the following items, with selected time |
||
|
weighting and frequency weighting |
|||
|
Instantaneous sound pressure level : Lᴘ |
|||
|
Equivalent continuous sound pressure level : Leq |
|||
|
Sound exposure level : LE |
|||
|
Maximum sound pressure level : Lmax |
|||
|
Minimum sound pressure level : Lmin |
|||
|
Percentile sound levels : Lᴎ ( 0.1 to 99.9 %, 0.1-increment steps, max. 5 values ) |
|||
|
Processing (sub ch) |
Instantaneous sound pressure level : Lᴘ |
||
|
Additional processing |
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 |
|||
|
ｴ-time-weighted equivalent continuous sound level : LAｴmax＊2 |
|||
|
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. |
|||
|
