Simulation of flanking transmission in super-light structures for airborne and impact sound
Super-light structures are an invention based on combining lightweight concrete with normal concrete for better structural performance and lighter structures. The overall principle is based on load carrying arches of a normal concrete stabilised and protected from fire by a light-aggregate concrete. Previously the airborne and impact sound insulation has been measured for a super-light deck element in a laboratory. This paper presents a flanking transmission analysis based on the measured results and are carried out for the Super-light deck elements by means of the acoustical software Bastian. In the flanking transmission analysis the influence of a large array of different flanking walls, structural connection details, room size and floor constructions, all typical or desirable for common multi-storey residential constructions, have been investigated. The results form a basis for guidelines on how to design buildings with super-light deck elements while achieving a good acoustical environment in the building, fulfilling various acoustical requirements from the building regulations.
