blog of acoustics, noise, vibration & audio-visual systems
I was recently interviewed by College Planning & Management magazine for their article on “How schools can create cafeterias and other social spaces to shout about, not over?” These spaces are where university students come to dine, to study, to relax, and to socialize, so why are they always so loud? And more importantly, what can be done to optimize these spaces for sound? Read the full article here http://www.peterli.com/cpm/resources/articles/archive.php?article_id=2616.
Letâ€™s play word associationâ€¦ Ready? Go: Academicâ€¦ Collegeâ€¦ Universityâ€¦ Higher Educationâ€¦ Acoustics! Did you picture the big wood paneled lecture hall filled with hundreds of students engaged in a lecture about world history, literature, or archeology? Yeah, me tooâ€¦ or at least that what I used to picture. (more)
This past summer I went to commission a small sound system at a new facility. Not necessarily a big expensive project, but the client had hired us to commission the final installation and make sure everything was installed as specified. I showed up on site, confirmed all of the equipment was installed and then proceeded to check out how the wiring had been installed. At first everything looked pretty good, until I pulled one of the microphone input plates off the wall and discovered that there was no junction box behind it. Instead someone had busted a hole in the masonry block and tried to fish the wires down through the block from above. But they had run into a little problem at the steel beam. So they made another hole through the vapor barrier and ran the wires just inside the exterior brick. Problem solved, right? Uhâ€¦ not so much. (more)
The education methods used in today’s universities are rapidly changing, and as the methods change, so does the architecture. The big buzz right now is creating “collaborative spaces for learning“. Traditional push down models of teacher-to-student lectures are being supplemented by a new focus on interactivity and, there’s that buzz word again, collaboration. So what are the acoustical challenges inherent in the new system? (more)
We were recently called in to assist in addressing a noise issue that was the result of a university’s desire to be more “green”. In this case, we were asked to assess the noise produced in the dish wash room of a university student union. This blog is the second of a two-part post about student union acoustics, and you may want to read the first blog on College Campuses and Student Union Acoustics before continuing. (more)
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.

Urban legends claim that a good way to calm your nerves before giving a speech is to imagine the audience in their underwear. But what if you could attend class in a T-shirt and underwear without anyone else ever knowing it? Well, at many colleges and universities around the world, you already can.
To understand this miracle of science, we have to examine the link between two rapidly changing technologies: distance learning and classroom connectivity. These two might seem unrelated, but in fact they are deeply intertwined. (more)
