Leipzig (dpa/sn) – At Leipzig/Halle Airport, all 13 systems for measuring aircraft noise have been checked. In the past two months, independent experts had determined, among other things, the maximum noise level per overflight, as the aircraft noise protection officer Jörg Puchmüller announced on Monday. Accordingly, the values ??measured by the systems are mostly accurate, but there were deviations at two measuring stations.
