Correction Value k1
The correction value k1 is based on an LAeq mea-
surement. It is measured or manually set in the
page K
SET of the sound level meter function.
Correction Value k2
The correction value k2 is based on either LCeq or
LCpeak measurement. It is measured or manually
set in the page K
SET of the sound level meter func-
tion.
Parameter live
Actual current sound pressure level.
Parameter max
Maximum sound level of the measurement cycle.
Parameter min
Minimum sound level of the measurement cycle.
Correction Value off
No correction value, default setting.
Peak Level
Application example:
Measure L
Cpeak
in accordance with DIN15905
The RTA spectrum analyzer measures the true peak
level with the optional Extended Acoustic Pack. The
peak hold time can be set to 0, 1 or 5 seconds.
Percentile Sound Level - Level Statistics
The statistical distribution of sound pressure levels
is commonly used for environmental noise analy-
sis, such as road traffic or community noise as-
sessments. For example L
AFxx%
is the noise level
exceeded during xx% of the measurement period;
e.g., LAF90% is the noise level exceeded during
90% of the measurement period.
Please see the specifications at chapter Technical
Data XL2: Functions of Extended Acoustic Pack
(optional) in this manual.
Previous Level
Applicable for timer mode Repeat or Repeat Syn-
chronized; displays the selected sound pressure
level of the last measurement cycle.
