Metal construction creates unique acoustic challenges, especially for large spaces with tall ceilings. This session will describe the history of acoustics and metal buildings – how they each developed and how they combine in the present day. We’ll dive into the best way to assess and fix these spaces using Day 1 and Day 2 approaches, and compare acoustical decking, banners, baffles, clouds, and panels. The most common unit in acoustics – NRC – will be demystified and the session will answer the question “How much do I need?”.
Learning Objectives:
- Explore the history of acoustics in metal buildings.
- Define and understand Day 1 and Day 2 approaches.
- Demystify the most common unit in acoustics: NRC.
- Compare acoustical decking, banners, baffles, clouds, and panels against each other.
- How structure, size, space, and specifically height affect the entire building’s acoustics.
