LCeq Time-Average Sound Level or
Equivalent Continuous Sound Level
Averaged sound level over time with C frequency weighting.
-> ->
LCpeak Peak Sound Pressure Level
Sound pressure level with C frequency weighting and peak time
weighting. Measures the peak level. High peak levels can dam-
age the human hearing.
-> ->
LCpeak max Maximum Peak Sound Pressure Level
Maximum sound pressure level with C frequency weighting and
peak time weighting. Measures the peak level. High peak levels
can damage the human hearing.
-> -> ->
LCpeak max dt Maximum Peak Sound Pressure Level „delta t” in report
Maximum peak sound pressure level with C frequency weighting
of the preset logging interval in the LOG-menu, e.g. 1 second.
LCpeak + k2 Peak Sound Pressure Level with Correction Value
The actual measurement position often differs to the loudest posi-
tion of the live event. Thus the correction value k2 is the correc-
tion value of LCpeak between the loudest position and the actual
measurement position, measured using pink noise. The correc-
tion value k2 is measured or manually set in the page K
SET of the
sound level meter function.
