under the condition: value of the Leq result ( Source )
integrated by the Logger Step period is greater than
the threshold level ( Level ). In other cases, the
logging is skipped.

integrated by the Logger Step period is lower than
the threshold level ( Level ). In other cases, the
logging is skipped.
