SNAFU-Situation Normal: Acoustics Fouled Up
Recognizing and avoiding common acoustics issues
Sponsored by Owens Corning® | Presented by Seth Harrison and Jon Mooney
Webinar On-Demand
In the spring of 2000, in response to noise complaints from neighbors and driven by low cost, the owners of The Station were primed to follow a chain of incredibly bad acoustic advice leading to the installation of flammable urethane and styrene foam on the walls and ceiling of their nightclub. During the next two years, at least one visiting band recognized the danger; however suppliers, building contractors, and three separate fire and building inspections did not.
Project requirements for architectural acoustics, noise/vibration isolation, speech privacy/intelligibility, and property line noise emission exist to meet federal law, building and fire codes, state and local ordinances and industry standards; as well as the owners design guidelines and desires. Although the owners guidelines and desires may be negotiable, inattention to other acoustic requirements leads to SNAFUs. A majority of these SNAFUs remain undetected, giving a false sense of project success. A few of these, like The Station nightclub fire, result in loss of life, millions of dollars in payouts and even jail time. Those that are detected typically generate field issues, expensive redesign and rework, and a loss of owner confidence.
In this webinar, two seasoned acousticians share some of the more common acoustic SNAFUs and suggest how to avoid similar problems.

Unresolved acoustic SNAFUs caused the U.S. Congress to quickly abandon the otherwise beautiful Hall of the House of Representatives shown here in Samuel Morse’s 1823 painting.
