This session will demonstrate how sound travels through building assemblies and how uncontrolled air movement is a primary pathway for sound transmission.
Join us to see how the proper installation of building materials, such as firestop systems and air barriers, helps restore and maintain sound transmission class (STC) performance by limiting air and smoke movement through penetrations and joints. (Since smoke travels on air, materials designed to contain fire and smoke also help mitigate sound transmission.) Plus, through real-world examples, you'll discover the connection between life-safety requirements and acoustic performance in wall and floor assemblies.
Learning Objectives
- Analyze how sound travels through building assemblies, and identify primary transmission paths related to air movement.
- Differentiate between laboratory STC ratings and real-world acoustic performance in penetrated and jointed assemblies.
- Examine how improper or missing firestopping and air-barrier continuity affect both sound transmission and smoke migration.
- Evaluate how specific firestop materials and installation methods influence the restoration of STC performance in rated assemblies.
