The overall aim of the research is to eventually develop a viable system, using Pinus radiata, for multi-storey timber buildings up to six storeys. One of the main issues is achieving sound resistant timber floors that are economically viable. This paper reports on the acoustic testing of a prototype floor built with Radiata pole joists. Measurements were made of the objective performance. The results indicate that the floor meets code requirements – even when it has a hard surface.
