My Scarlet Letter | Distractions in the Classroom

Tim Koldenhoven | K-12 Education | May 27th, 2009 | 5 Comments

At Acoustics By Design we talk a lot about standards.  Sometimes, the standards are hidden behind terms like design goals, baseline design, or even ordinances and specifications… But they are all standards.

At Acoustics By Design, we regularly consult on the design of College and University buildings including classroom buildings, dormitories, athletic facilities, performing arts buildings, libraries, research buildings, and student centers. These numerous building types result in our needing to address a myriad of acoustic and vibration issues. Many student centers and student unions face a similar problem: loud noise from the commercial kitchens inhibit the relaxed social environment for the students. Universities want their student unions to be a center for campus life and activity, and if the student center is too loud to provide the desired environment, students will inevitably congregate elsewhere.
