Excessive sound can negatively impact the health and well-being of occupants. This has resulted in a growing trend to improve the acoustical performance of building assemblies. Due to this, there have been significant changes in the 2015 National Building Code of Canada (NBC) moving from sound transmission class (STC) to apparent sound transmission class (ASTC) ratings that reflect assemblies that provide increased levels of acoustical performance. The course will explore how laboratory acoustical testing is performed, the principles of sound control, the different methods of sound transmission within buildings (airborne, impact, and flanking), and how to meet the 2015 NBC requirements for ASTC ratings.
Upon completion of this course, the Learner should be able to:
- Explain how an STC test is performed as defined by test standard ASTM E90.
- List three ways sound transfer occurs through an assembly.
- Describe the principles of sound control that can be utilized to improve acoustical performance.
- Identify what materials are acceptable as "sound absorptive material" as defined in 2015 NBC.
- Design an assembly to satisfy ASTC requirements in 2015 NBC.
