Learning Objectives:

  1. Quantify the term “good acoustics” from the project requirements.
  2. Match those project requirements to appropriate acoustic design options.
  3. Match those acoustic design options to appropriate performance requirements.
  4. Judge the equivalency of proposed substitutions and their effects on the project.

Every architect, engineer and constructor who has worked on a project having specific acoustics, noise and vibration requirements knows the project’s specified acoustic materials and assemblies are a constant target for the general contractor’s cost-reduction efforts. Due to their highly specialized performance requirements, acoustic materials and assemblies tend to be high-priced and labor intensive when compared with the non-performing components they replace. RFI’s, submittals and shop drawings all propose lower cost solutions, but are they truly equivalent?

In this webinar, two seasoned acousticians explore this question and show how to determine if proposed substitutions will still allow your project to meet its acoustics and vibration requirements.

Seth Harrison is the Managing Principal of Harrison Acoustics, an acoustics and vibration consulting firm near Philadelphia. His diverse career in acoustics ranges from architectural acoustics consulting to research and development of noise control techniques for jet engines. As a licensed professional engineer in PA, NY, and IL with field experience commissioning building systems, he has a firm grasp of constructability and cost implications related to noise and vibration control within buildings. Seth is an active member of the Institute of Noise Control Engineering, the Acoustical Society of America, and the American Society for Testing and Materials. He currently serves as the Vice-Chair of the Philadelphia Chapter of the ASA and as a voting member of ASTM Committee E33 on Building and Environmental Acoustics.

Principal Consultant, Jon Mooney started his career as an Aerospace Engineer working on spaceflight and defense industry programs. His work includes design and analysis of systems for SkyLab, Space Shuttle, Patriot missile and anti-submarine sonar systems. During this time, he developed advanced acoustic modeling and simulation techniques, which we now use to accurately model and simulate the acoustics of architectural spaces. Jon is an active member of the Institute of Noise Control Engineering, Acoustical Society of America, American Institute of Aeronautics and Astronautics, International Council for Systems Engineering, INCOSE Infrastructure Working Group, and INCOSE Smart Cities Initiative. He is Associate Editor of Architectural Acoustics for Noise Control Engineering Journal, Acoustics Advisor for Walls & Ceilings magazine and writes technical book reviews for various publications.
