The sound level meter runs as a frequency analyzer and processes the acoustic signal according to the temporal mode:
On a T(D) measurement duration with data storage for each DI elementary integration time
Measured and stored data for each integration time:
•
LAeq, DI:
equivalent continuous level of sound pressure on the elementary integration time.
•
LCeq, DI:
equivalent continuous level of sound pressure on the elementary integration time.
•
LXeq, DI
: equivalent continuous level of sound pressure on the elementary integration time filtered by octave bands from
16 Hz to 16 kHz (class 1) or from 31.5 Hz to 8 kHz (class 2).
•
LUpk:
level of maximum peak of sound pressure on the elementary integration time.
