| Abstract | A large systematic study was carried out by the National Research Council-Institute for Research in Construction (NRC-IRC) to evaluate a wide range of floor-ceiling designs to control transmission of airborne and impact sound between vertically adjacent rooms. As impact sources, the tapping machine according to ASTM E492 as well as the heavy sources, the ball and the 'bang-machine', according to JIS A 1418-2 were used. The first part of the study was a parametric study. The direct sound transmission of a large series of floor-ceiling assemblies was measured systematically in the NRC-IRC Floor Transmission Facility to understand the complex interaction of the various structural components and to optimize noise control measures. The second part of the study was a flanking study. A number of floor-ceiling assemblies that achieved good direct sound insulation in the parametric study were selected and their system performance was measured in the NRC-IRC Flanking Transmission Facility. The system performance is determined by the apparent sound transmission which is the sum of the direct transmission and the flanking transmission via the floor to the walls below. This paper presents some findings from this flanking study. Only impact measurements with the tapping machine are presented in this paper. |
