Airport and airfield noise zone

In spatial planning, the authorities designate a noise zone around noise sources, where the noise level exceeds the recommended noise limit.

In spatial planning, the authorities designate a noise zone around noise sources, where the noise level exceeds the recommended noise limit. Below is a review of recommended noise limits for airports and airfields.

The recommended noise limits for airports and airfields are found in Guidelines from the Danish Environmental Protection Agency, no. 5/1994 "Noise from Airfields" (in Danish). They are used both for environmental permits and for spatial planning.

The recommended noise limits are expressed as DENL values (L den ), which is the A-weighted average noise level over 24 hours including a 5 dB penalty for events during the evening period (19-22) and a 10 dB penalty for the night (22-07). In addition a 5 dB penalty applies to special aircraft activities (such as parachute flying, visual training flights, scenic pleasure flights, ultra light flying, etc.) in weekends and in the evening and night on weekdays.
