Daily Personal Noise Exposure is the noise
exposure level for a nominal 8-hour working
day. The LEPd result is calculated on the
base of the LEQ
The Ltm3 and Ltm5 results (Takt-Maximal Levels) are calculated according to the
German standard TA Lärm.
Statistical level is the certain boundary level
surpassed by the temporary noise level
values in not more than n% of the observation
period
Example: Let us assume that L35
is equal to 76.8 dB. It means that
during the measurements the
noise level 76.8 dB was exceeded
in not more than 35%
of the observation period.
