With higher densification in urban centers, issues of sound insulation are becoming increasingly important in North America. Historically, requirements for sound insulation have focused on the transmission directly through the separating building assembly. However, in practice a significant proportion of the sound between two adjacent rooms travels via flanking paths, for example a common floor or ceiling. In recognition of this fact, the 2015 edition of the National Building Code of Canada sees a change from requirements for building element performance (STC rating) to requirements for system performance (Apparent STC rating). A large-scale research project is currently underway at the National Research Council Canada to investigate the flanking sound transmission in cold-formed steel-framed constructions and to provide data for builders and architects. The project is a collaboration between the National Research Council Canada and the Canadian Sheet Steel Building Institute. This presentation will cover the basics of sound transmission through steel-stud walls and floors before focusing on issues of flanking sound transmission in cold-formed steel-framed constructions.

Presenter

Dr. Christoph Hoeller is a Research Officer in the Acoustics Group at the National Research Council Canada. He is responsible for a range of different projects pertaining to sound transmission in buildings and human perception of sound, and currently leads a large-scale research project on the direct and flanking sound transmission in cold-formed steel-framed constructions. Dr. Hoeller obtained an MSc from RWTH Aachen University in Germany and a Ph.D. from the University of Liverpool in the UK. He is a member of the Acoustical Society of America, the European Acoustics Association, and the International Institute of Acoustics and Vibration.
