Lmax Maximal value of the time-weighted sound pressure
level at the exponential RMS detector output within
the elapsed measurement time. The
Max result for
the 1 second period is equal to the Spl result. It is
measured with frequency weighting A, C or Z and
time weighting F, S, I and displayed as LAFmax,
LASmax, LCFmax, LCSmax etc.
Appendix D
Lmin Minimal value of the time-weighted sound pressure
level at the exponential RMS detector output within
the elapsed measurement time. It is measured with
frequency weighting A, C or Z and time weighting F,
S, I and displayed as LAFmax, LASmax, LCFmax,
LCSmax etc. Appendix D
Leq Equivalent continuous sound level, time-averaged
sound level for the elapsed measurement time
(equivalent sound level). It is measured with
frequency weighting A, C or Z and accordingly
displayed as LAeq, LCeq or LZeq. Appendix D
L Time weighted sound level expressed at
observation time, expressed in dB. It is measured
with frequency weighting A, C or Z and time
weighting F, S, I and displayed as LAF, LAS, LCF,
LCS etc.
Appendix D
LE
Sound Exposure Level (SEL), the constant sound
level that has the same amount of energy in one
second as the original noise event and is the subset
of the
Leq result so, for the integration time equal to
1 s, SEL is always equal to Leq . It is measured with
frequency weighting A, C or Z and accordingly
displayed as LAE, LCE or LZE.
Appendix D
LEPd Daily Personal Noise Exposure, the noise exposure
level for a nominal 8-hour working day, used for
assessing the noise exposure of a worker during a
working day. The
LEPd result is calculated on the
base of the Leq .

Takt-Maximal Level calculated according to the
German standard TA Lärm. Appendix D
Ltm5
Takt-Maximal Level calculated according to the
German standard TA Lärm. Appendix D
