Abstract

Researchers from the National Research Council designed and built a flanking facility to investigate the way flanking paths affected the sound insulation performance of building systems. The facility had a number of specific features to help the researchers conduct the investigations. The research facility had 8 rooms or 8 walls, 4 floors, and 6 junctions, enabling evaluation flanking of bearing and non-bearing wall and floor junctions, along with wall paths with a single specimen. Fixed surfaces were large and isolated from one another using resilient mountings to ensure that the facility did not contribute to vibration transmission. Each room had a volume that differed by around 10% from adjacent rooms to avoid modal matching and follow the recommendations of ISO 140 standard. The entire facility was also run by a computer system that controlled noise sources, robot movements, and signal capture.
