EASURED RESULTS
Position Description Screen Reference
Elapsed time Time from the measurement start, that is displayed
under the result in the format
⌛
mm:ss in the range
from 00:00 to 59:59, or in the format
⌛ hh:
mm:ss in
the range from 01:00:00 to 99:59:59, or in format
⌛
xxxh from 100h to 999h, and
⌛
>999h if the
elapsed time exceeds 999 hours. Its maximum
value is equal to the
Integration Period and the
elapsed time is zeroed when new measurement
cycle starts.
Chapter
5.1.1
OVL Percentage of the overloaded input signal, which
occurred within the elapsed measurement time. Appendix D
Lpeak Peak Sound Level, the greatest instantaneous
value of a standard frequency weighted sound
pressure level within the elapsed measurement
time. It is measured with frequency weighting A, C
or Z and accordingly displayed as LApeak, LCpeak
or LZpeak. Appendix D
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.
