MIN_dt
Minimum SPL value measured within the actual log interval ∆t;
time weighted value (SLOW/FAST).
MAX_dt
Maximum SPL value measured within the actual log interval ∆t;
time weighted value (SLOW/FAST).
Example of an SPL/LEQ log visualized with Microsoft Excel
(without LcPEAK)
LcPeak
Maximum C weighted peak sound pressure level during the
whole measurement period. The measurement period is
indicated and controlled by the measurement timer.
LcPeak_dt Maximum C weighted peak sound pressure level during the
log interval ∆t.
SPL_Act
Indicates the actual SPL level measured exactly at the end of
the log interval. Please note that LEQ_dt, MIN_dt and MAX_dt
characterize an interval more accurate than this single
SPL_Act value.
