Passive sound-proofing

Voluntary support programme

As part of a voluntary support programme which ran from 1996 to 2002, financial support was provided for structural sound-proofing measures for people living close to the airport. Finance was provided for the installation of sound-proof windows in living rooms and bedrooms and for the installation of sound-proof ventilation systems in bedrooms. The investment volume of the support programme was approximately EUR 2.8 million. This made a vast improvement to the living conditions for more than 1,550 local residents
(640 households).

Renovation and extension of the runway

In 2006 and 2007, Dresden Airport completely overhauled and extended its runway by 350 metres to 2,850 metres. As part of the planning approval procedure, expert assessments on aircraft noise were submitted. The noise exposure from aircraft noise and from ground handling operations likely to be caused during the project was calculated on the basis of an airport development forecast up to the year 2020. These findings were then evaluated in a noise-related health impact report.

In its planning approval decision of 25 October 2005 the planning approval authority imposed certain noise protection requirements. Among other things, the decision read:

"At the request of the owner of a site located completely or partially within the noise protection zone which was developed or was suitable for development on 17 January 2005, Flughafen Dresden GmbH must perform the structural physical tests and calculations of the necessary sound-proofing measures and must provide appropriate sound-proofing in living rooms and bedrooms. The sound-proofing must guarantee that inbound and outbound flights do not cause individual sound levels in excess of 55 dB(A) inside these rooms both by day and at night with the windows closed. The sound-proofing must also guarantee that the overall level of airport-generated noise (flight and ground noise) does not exceed a permanent sound pressure level Leq(3) of 40 dB(A) in living rooms by day and 35 dB(A) in bedrooms at night. If the noise protection offered can only be achieved at night by keeping windows closed, Flughafen Dresden GmbH must, at the owner's request, install ventilation in bedrooms and ensure that the difference in outdoor and indoor sound levels with windows closed is at least 25 dB(A).

The noise protection zone for both daytime and night-time protection encompasses the area in which an energy equivalent permanent sound level Leq(3) of at least 50 dB(A) is forecast during night hours (22:00 - 06:00) in the six busiest months (Annex 1, Noise Protection Zone). The ceiling is calculated taking all airport-generated noise into account."

The closing date for applications was 31 August 2009, two years after the renovated and extended runway was put into operation. Approximately 480 applications for noise protection for more than 2,050 homes in the vicinity of the airport have been received and are currently being processed. In more than 85% of these cases, structural measures have already been put in place or it has been established that the existing structural measures are adequate.

Noise map "Aircraft noise level ranges according to DIN 4109"

According to the Saxon building law, the owner of newly constructed or reconstructed buildings is responsible for ensuring that they are sufficiently soundproofed. To enable the owner to meet this obligation, Dresden city council has identified the areas in the territory of the city of Dresden in which higher exposure to aircraft noise can be expected in a so-called Environmental Atlas.

Based on the official noise map, it can be determined whether a noise study needs to be performed for a building project and which noise level range as per Table 8 of DIN 4109 "Sound Insulation in Buildings" applies. This data enables professionals such as architects, civil engineers or sound engineers to incorporate adequate acoustic measures into the building's exterior components.
