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 .

German standard TA Lärm. Appendix D
