A New Approach to Building Acoustics Regulation in Canada
AbstractA new approach to the control of sound transmission is among the proposed changes in the 2015 edition of the National Building Code of Canada. The design objective is changing from a minimum direct STC for the wall or floor/ceiling assembly separating adjacent units to a requirement for the Apparent Sound Transmission Class (ASTC) that includes direct and flanking transmission. The approach to design is based on combining the ASTM data from conventional laboratory measurement of direct transmission through wall or floor/ceiling assemblies with measurements of flanking transmission conforming to ISO 10848 and calculation procedures based on ISO 15712-1. This paper focuses on explaining the technical intent and form of the proposed new Code requirements.
