How Today’s Teachers Use Classroom Display Technology
Kids today have it all: the cell phone, the iPod, the iPad, the internet, digital cameras, video games, laptops – ahhh!!! With all this stimuli, teachers have to battle to win the ever-decreasing attention spans of their students. And any teacher knows the statistics of how students learn: most of what they get their hands on (tactile learning), some of what they see (visual learning), and little of what they hear (aural learning). The good news is that new classroom display technology enables teaches to fire on all cylinders and teach fluidly while using all three methods of communication. So, how are teachers doing it? (more)
Football Stadium Sound System Design | How to Control the Friday Night Roar
It’s 7pm on Friday night in the middle of September. You’re sitting down with your significant other to a nice refreshing beverage on your back porch. All is calm. It’s a beautiful evening. Suddenly a not-so-distant voice floats through your backyard let you know that #58 has just tackled #23 on the 35 yard line. You are, once again, thankful that your peaceful and idyllic life has been interrupted by the sound system from the local High School football game. No…you wish there was some way to contain that sound to the stadium where it’s supposed to be (NOT in my backyard)! (more)
American Disabilities Act to Accommodate Hearing-Impaired Students
The phrase “Equal Access” might not be very exciting, but it represents what many perceive to be a fundamental right of modern society. Every building built in the last 20 years has personified “Equal Access” by including doors wide enough for a wheelchair, elevator signage with braille lettering for blind persons, and auditoriums with hearing assist systems for those hard of hearing. While children in wheelchairs have “Equal Access to Learning” in school classrooms today, those with hearing difficulties are denied the same opportunity. In many classrooms, the students cannot hear the teacher due to the loud mechanical system or the nearby airport. And, if they can’t hear, they can’t learn. But that’s all about to change. (more)
Not All Acoustical Surfaces Are Created Equal
The orchestra that I play in used to perform at local public schools. The high school auditoria that we regularly used were so-so for acoustics, but we learned to appreciate them when a scheduling conflict bumped us to a junior high school for one concert. This auditorium ceiling was treated with a spray-on absorbing material that made it feel like we were playing into a sonic black hole. After we finished, it sounded like twenty people were clapping, which I hope there were more…maybe not if they couldn’t hear us. (more)
Naturally Ventilated Buildings and Loud Noisy Acoustics
The LEED® green building certification program gives out points for naturally ventilating buildings, and it also gives out points for acoustics – especially for low levels of background noise levels. As the industry is finding out, naturally ventilated buildings create more opportunities for buildings to be penetrated by exterior noises, thus creating unintended loud background noise levels. I was interviewed by Buildings Magazine for their article, Fresh Air Creates Fresh Acoustical Concerns. Read the whole article here… http://www.buildings.com/ArticleDetails/tabid/3321/ArticleID/10021/Default.aspx
Reflections at Little Beaver Lake
On a beautiful autumn day a long time ago, I was on a glorious backpacking trip to Pictured Rocks National Lakeshore in Michigan’s Upper Peninsula. One still morning while rinsing off in Little Beaver Lake, I was alarmed to hear voices that sounded very near, as I was sporting my birthday suit. After quickly sinking into the water up to my neck, I searched for the people and to my relief found them on the opposite shore of the small lake, out of “detailed sight” range. That was a memorable lesson in how well water reflects sound. (more)
Gymnasium Acoustics | The Multi-Use Problem
Gymnasiums often end up being multi-use spaces. Of course, they are used for competitive sporting events, for team practice, recreation, and for Phys Ed classes. But they are also used for school addresses, commencement ceremonies, band and choir concerts, and more. Those with stages are used for musicals, plays, and speaking events. I have been asked to help mitigate acoustical problems more often in gymnasiums than in any other type of school space; possibly more often than in any other type of space, period. And there are almost always two complaints that I hear… (more)
Space Savers | Acoustical Engineering for Gymnatoriums and Cafetoriums
It certainly isn’t a new idea… How do we maximize our space and minimize our cost without the loss of function? Surely this is the major driver behind ideas like the gymnatorium or the cafetorium. We’ve all seen them, most likely they were in the schools that we attended. They consist of a stage at one end of the room or tucked away in the corner. So, do these budget savers really work like they are supposed to? (more)
My Scarlet Letter | Distractions in the Classroom
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. The reality is almost all aspects of our lives are governed by standards; regardless of how well they work or how well we adhere to them, we still use them in decision making. (more)
Digital Signage Solutions for K-12 Schools
My wife teaches English to high school freshmen and seniors. It’s a good thing that she’s the one teaching them, because if it were me, I’d probably end up in a mental institution. The hard part about teaching teenagers is finding effective methods of communication. Sometimes it seems like they just don’t understand words. But there are things they do understand. High school teenagers understand images. They understand video. They understand multi-media, multi-sensory communication. This is one of the reasons why we at Acoustics By Design are seeing a significant uptick in Digital Signage system design for K-12 schools. (more)
