AbstractA number of assumptions and simplifications are introduced when applying the mobility approach to predict structure borne transmission from wood studs to gypsum board that is directly attached by screws or nails. This paper examines the error introduced by three of the many simplifications. It is shown that studs do deform volumetrically, and there is a strong dependence on contact area between the studs and gypsum board. Also transmission at ill-defined contact points between the fastening points becomes important when there are few fasteners. Assumptions that ignore these factors may introduce bias errors but these oppose each other so that it is possible to achieve reasonable agreement between measured and predicted results despite incorrect theoretical foundations.
