Event duration in sec
In our calculation, the noise curve of each event is approximated by a triangle.
Only the red area is used for calculation.
(Noise which is not less than LASmax - 10 dBA)
||10 events with a maximum level of 70 dBA and an event duration of 90 sec (related to a base-level of 30 dBA) will result in the following average sound indicators if averaged for certain given periods of time:|
