Opening the Door to Better Classroom Acoustics
Last year, I was presented with a unique opportunity to apply our building science research into a real-life application — the renovation of an elementary school in northeastern Pennsylvania. Originally built in 1973, the school was transformed from an open concept interior space into individual state-of-the-art classrooms. Superior acoustical comfort, which can contribute to improved student performance and teacher retention, was a top priority in this field study as well as an analysis of the overall indoor environment that included air quality, thermal comfort and visual comfort measurements.
Our goal was to investigate the impact of installing different, high-performing interior acoustical ceiling and gypsum wallboard system solutions in six new classrooms constructed in the third grade student wing. Acoustical tests were conducted in each classroom to determine sound absorption and interior partition sound transmission levels, as well as major sound flanking paths.
As a leading manufacturer of ceilings and wall products, our team is well versed in the myriad of product specifications and configurations for our products. However, during the testing, I had an a-ha moment of sorts regarding the doorways to the classrooms.
Specifically, I realized that even though it is well known that acoustically isolated, airtight door assemblies improve classroom acoustics when used in conjunction with high-performance gypsum board and ceiling products, these elements are often specified independently rather than a comprehensive acoustical system. This is a challenge that I have always been aware of, but seeing it so clearly in this study led us to ask: what could we do about it?
Our curiosity led us to ASSA ABLOY, the global leader in door opening solutions. Through our alliance, we’ve uncovered easily accessible solutions found in door and frame systems, to address acoustical challenges and reduce the sound reverberation that further complicates noise issues in classrooms.
We look forward to sharing more detailed findings during Greenbuild 2013 through a dedicated education session at the Saint-Gobain Learning Lab. Please join us at the session or leave us a comment below to continue the discussion.
