Abstract [en]

Lightweight multi-storey timber buildings based upon prefabricated volumes is a technique of increasing interest. A great advantage is that the technique encourages the use of elastic layers in between floors and also to have a construction where the upper floor is disconnected from the lower ceiling besides at the boundaries. But, in accordance to similar constructions, it might be troublesome to obtain good sound insulation, particularly at low frequencies.In this paper the airborne sound reduction and impact sound pressure level are investigated. The object is a six-storey apartment house which is characterised by the amount of storeys which is large with respect to the building technique. The demands then increase regarding the overall constructional design as well as the design of the elastic layers in between floors which have to be stiffer. It is therefore of great importance to study whether these parameters cause deterioration regarding sound properties.
