Zusammenfassung:This line of inquiry aims to provide field-measured impact noise data for ‘‘box-on-box’’ construction, as was found in field tests. This type of construction holds the potential to increase impact isolation class (IIC) because the very process of building discrete boxes off site, transporting them, and stacking them on-site, establishes an airspace between the floor joist of one box and the ceiling joist of another. This partially decouples the floor and ceiling (a ridged connection remains at the perimeter of the boxes). A preliminary test of wood finished flooring yielded an FIIC of 42. Ongoing supplemental tests with floor underlayments and resilient seismic connections at the perimeter of the boxes will also be presented.
