The acoustic properties ofmulti-family wooden frame buildings were considered. Full-scale models of a floor, a dividing wall and an opaque part of a façade were examined in the laboratory. The measurements were taken at different phases of the sample’s construction to determine the contribution of their particular elements to the total sound insulation of the final structure. The acoustic effect of a floating screed and a suspended ceiling was analysed for the floor. Different assembly methods of the ceiling were investigated, and the flexible channels were significantly more effective than rigid wooden battens. The impact sound insulation improvement of the floating screed seemed lower when it was use on a lightweight floor in comparison to a traditional massive slab. The ceiling and the screed should be used together to satisfy the requirements. In the case of a dividing wall, various types of timber frames were examined, the single wall with additional insulating cladding and the totally separated double wall achieved a performance level adequate for residential use. The application of elastic dividers and resilient spacers was of critical importance for the effectiveness of the additional insulation. The results are useful for engineers and designers when working on high-quality residential buildings with good acoustic performance.
