A review of a uniquely designed floated jack-up concrete slab to isolate fourteen movie theaters on multiple floors within a multi-use building. The jack-up boxes were engineered and custom tailored to increase airborne sound transmission loss performance while achieving a very high vibration isolation efficiency specified. Field test results were obtained to validate the floating jack-up concrete’s acoustical performance.
