The design of sound insulation measures for dwellingsaround Amsterdam Airport Schiphol

摘要

In the surroundings of Amsterdam Airport Schiphol approximately 14000 dwellings are being sound insulated. Half of the dwellings will receive low level insulation ranging from 20 to 27 dB(A), half will receive high level insulation ranging from 30 to 40 dB(A). The measures varyfrom improving airtightness and ventilation silencers to heavy provisions to roofs and windows or even replacement of dormers. Especially the large number of dwellings with relatively low required sound insulation level emphasizes the importance of an efficient engineering process. Peutz wasinvolved in the methodology of the acoustical design of both the low and the high level sound insulation. To reduce engineering and insulation costs acoustic design methods have been developed and implemented in computer programs, based on optimization of costs. Special attention has beenpaid to the sound reduction by the building itself, depending on the angle of incidence. The qualitycontrol by laboratory measurements of the sound insulation of building elements was essential for theacoustical result of the project.
