Continuing Education: 1.5 Hours Available


Urban centers in North America are experiencing an increase in densification, leading to a high demand for mid-rise and high-rise buildings. With the rise of such buildings, issues of sound insulation are becoming increasingly important.

In a recently completed large joint research project between the National Research Council Canada (NRC) and the Canadian Sheet Steel Building Institute (CSSBI), the sound transmission characteristics of cold-formed steel-framed buildings were investigated. A special focus was on design details that will allow builders to meet the new acoustic requirements in the National Building Code of Canada (NBCC). In recognition of the importance of adequate sound insulation in multi-family buildings, the 2015 edition of the NBCC has seen a change from requirements for building element performance (STC rating) to requirements for system performance (Apparent STC rating).

The presentation will review the new sound insulation requirements in the NBCC, highlight tools and guidelines provided by the NRC, and demonstrate how the acoustic requirements in the NBCC can be met for buildings constructed from cold-formed steel-framed walls and floors.

About the presenter

Dr. Christoph HoellerDr. 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. The current focus of his work is on supporting the transition to ASTC metrics in building regulations in Canada by developing tools and guidelines in collaboration with Canadian industry partners. 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 Canadian Acoustical Association, the German Acoustics Association, and the International Institute of Acoustics and Vibration. Dr. Hoeller serves on the ASTM committees on building and environmental acoustics, as well as the Canadian mirror committees for ISO standards on building acoustics.
