2020 CFSEI Virtual Expo – BOOM! Acoustics for Cold-Formed Steel Wall and Floor Systems

Part of Live Sessions – Aired on September 3, 2020

Continuing Education Credits Available – 1.5 PDH Credits

As structural engineers, we are very good at designing buildings for loads and resistance, but typically have not had any formal training in things like fire ratings, acoustical ratings, air/vapor/moisture barriers, and how all of these attributes are affected by the structures we design. Unfortunately, this presentation won’t be long enough to cover all of these issues, but it WILL give you a good foundation in acoustics for structures and help you understand how your structural design will affect acoustical ratings of floor and wall systems. As cold-formed steel (CFS) makes more inroads into mid-rise and multi-family structures, acoustics are becoming more of an issue. After attending this presentation, you will better understand what STC and IIC are and how they are measured and interpreted, and the differences between field-measured and lab-measured values. You will also learn how things like stud thickness, joist spacing, and even connection details like ledger framing can help or hurt acoustic transmission. You will learn about the strategies that architects are using (or trying to use) to achieve better sound performance, as well as products available for this purpose that may affect structural performance. This presentation will be accompanied by a multi-page detailed handout with charts, diagrams, and pictures illustrating the principles discussed. It will also include references to code-mandated acoustical performance, and address how your design will affect that performance.
