Presented by Ben Shafer, MS (Physics), Acoustic Systems Specialist, PABCO Gypsum (USA)
Does varying the steel stud gauge really cause the STC rating to change?
Can a loadbearing, structural-steel interior partition also be acoustically rated?
How do cross-bracings, channel stiffeners, blocking, and door frames affect STC ratings?
What is the variation between STC lab results and actual field performance?
Should specifications identify different STC levels for assembly framing designs of different steel gauges?
What are best practices for achieving, or even exceeding, BC Building Code STC50 in the field for multifamily party wall and corridor wall designs?
Ben Shafer will answer these questions, and more, as he provides a comprehensive overview of designing acoustically-rated interior partitions for a variety of steel stud configurations, including partitions with structural requirements. The differences between ASTM E90-09 (sound transmission loss/STC) lab tests, typically performed on 25 gauge steel studs, and the real world sound isolation performance of interior partitions that have structural components such as cross bracing, channel stiffeners, blocking and door frames will be addressed. He will also introduce and explain new sound isolation measurements and standards related to SPC (Speech Privacy Class) and ASTC (Apparent Sound Transmission Class).
Ben graduated with a Master of Science (Physics) degree from Brigham Young University (BYU), is a voting member of the Acoustical Society of America (ASA), and actively participates as a member of the Structural Acoustics and Vibration Technical Committee within ASA. He is a full member of the Institute of Noise Control Engineering (INCE), and currently serves as secretary for the ASTM E33.03 sub-committee on Sound Transmission. Ben has close to a decade of field experience in acoustics and noise control for multi-family residential, hospitality, healthcare, transportation, and education sectors throughout Canada and the US.
