Outline
Additional processing
One of the following measurements can be selected for simultaneous
processing with main processing.
C-weighted equivalent continuous sound level
L
Ceq
C-weighted peak sound level
L
Cpeak
Z-weighted peak sound level
L
Zpeak
I-time-weighted equivalent continuous sound level
L
AIeq
Takt-max A-weighted sound level
L
Atm5
Maximum I-time-weighted equivalent continuous sound level
L
AImax
(When the optional Extended Function Program NX-42EX is not installed,
L
AIeq
and
L
AImax
cannot be measured.)
The following options are available separately, to further enhance the
range of applications for the product.
Level recorder LR-07
For recording sound level changes over time.
Data management software for environmental measurement
AS-60, AS-60RT
Total software of the environmental measurement for performing
management of data.
