Apparent sound insulation in precast concrete buildings
This Report presents the results from experimental studies of airborne sound transmission, together with an explanation of calculation procedures to predict the apparent airborne sound transmission class (ASTC) rating between adjacent spaces in a building with walls and floors of precast concrete. This Report was developed in a project established by the National Research Council of Canada and The Canadian Precast/ Prestressed Concrete Institute to support the transition of construction industry practice to using the ASTC rating rather than STC for sound control objectives in the National Building Code of Canada (NBCC). However, the potential range of application goes beyond the minimum requirements of the NBCC. The Report also facilitates design to provide enhanced levels of sound insulation, and should be generally applicable to buildings with precast concrete walls and floors in both Canada and the USA. Buildings assembled from precast concrete elements commonly have floors of hollowcore precast concrete slabs combined with wall panels of solid reinforced concrete. The building may also include linings on the precast concrete wall, ceiling, or floor surfaces, but this Report focusses primarily on performance of the base constructions of precast concrete. ; Peer reviewed: No ; NRC publication: Yes
