12CE - ASTC Ratings 2019 OBC: Component to System Design

23 May 2018 4:00 PM - 5:30 PM

1.5 ConEd Learning Hours

Sound transfer from unit to unit has been shown to have negative impacts on occupant health. With municipalities across Ontario trending developments toward intensification as opposed to urban sprawl, the issues of excessive sound transfer and occupant complaints will only continue to increase. This course explores the difference between laboratory acoustic testing and in-field testing, defines the code requirements to achieve compliance with Apparent Sound Transmission Class (ASTC) ratings and provides designers with three levels of assemblies that will meet 2019 code and the next two code cycles beyond.

Learning Objectives

    1. Learn the limitations of lab acoustical tests and how results translate to in-field performance.
    2. Understand three modes of sound transfer: airborne, impact and flanking.
    3. Know how to meet objectives of ASTC ratings in 2019 Ontario Building Code.
    4. Define acoustical systems to meet 2019, 2024 and 2029 editions of the Ontario Building Code.
