About This Program

In contemporary building design, the significance of sound control has never been more pronounced. A fundamental grasp of acoustical terminology and the principles of sound transmission is crucial for designing wall partitions that align with project-specific performance goals, adhere to code requirements, and align with industry standards. This course delves into six key concepts that have the potential to affect STC ratings in wall assemblies, allowing for the realization of desired acoustical performance.

Session Takeaways

  • Examine key acoustical concepts and terminology, including STC, decibels, hertz, and frequency.
  • Review code requirements and industry guidelines for sound transmission between adjacent spaces and explore how sound is transmitted through wall partitions.
  • Learn six concepts that can influence the STC rating of a wall assembly.
  • Investigate product options and formulate design strategies to achieve STC performance criteria.
