Holland. The country below the sea level with its entire landscape, water and dikes. These elements are used to create an noise reduction device what the inconvenience of noise of airplanes for the residents of Hoofddorp greatly reduced. A temporary water screen. A dike body finished with natural stone is parallel to the runway. On either side run channels. The dike is located at a distance of 150 metres from the runway. About the dike body is a high pressure water pipe. When a plane takes off or land is a waterscreen from 6 metres high under pressure sprayed. The waterscreen follows the movement of the airplane. The water is collected in the channels and reused. The required energy for the pumps and high pressure installation is generated with solar panels. The temporary waterscreen screens the sound. The new hilly land scatters the sound and the vegetation absorbs the sound. By the temporary nature of the waterscreen the sight lines in the landscape stay. The height of the different elements is nowhere higher than 1.5 metres above ground level (eye level). The temporary and moving waterscreen provides a spectacular view during take off and landing of airplanes. By applying of sustainable and natural materials is the noise reduction device a part of the landscape.
