Design Detail for Good Acoustics: Part 2 - Ceilings

Acoustical design requirements are frequently based on laboratory test data. Floor/ceiling assemblies constructed in a lab for testing are built under ideal conditions and with high levels of precision. These assemblies also do not have any of the attachments or penetrations that are ubiquitous in real-world construction. Selecting a tested floor/ceiling design that meets an STC and/or IIC requirement is not enough to provide adequate sound isolation in the real-world. To achieve good sound isolation, it is imperative that designers understand how to treat the myriad of details that can compromise a floor/ceiling assembly's performance. These include: can lights, soffits, control joints, window shades, access panels, speakers, and wall/ceiling intersections. In this presentation we: discuss why a detail is important for noise control, provide the acoustical impact of poor detailing based on test data (when available), and provide acoustical best practices for the details.

Approximately 1 hour. Delivered via webinar or face-to-face presentation. Available sessions shown below.
