AbstractA study was conducted to investigate the effects of structural load and joist type on flanking sound transmission in the NRC flanking facilities. Measurements were performed at two NRC flanking facilities, such as he first generation four-room and second generation eight-room facilities to assess the effects of these parameters. The appropriate surfaces of the rooms were shielded to limit the sound transmission to the paths being investigated. The first part of the study dealt with the reproducibility of load and general tendency of the effect of loading. The second part dealt with the effect of loading relative to joist orientation and continuity. The initial study investigated flanking sound transmission experienced between two horizontally separated rooms with discontinuous joists perpendicular to the separating wall.
