Digital Signage Solutions for K-12 Schools

Tim Hamilton | K-12 Education | November 26th, 2008 | Leave A Comment

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)

Noise Isolation for Mixed-Use Developments

Administrator | Mixed Use | November 20th, 2008 | 2 Comments

In the world of architecture, we frequently hear the term “mixed-use development,” and our firm is increasingly called upon to provide mixed-use development acoustical consulting. The term “mixed-use” generally refers to a development that incorporates residential and commercial space in a close-knit fashion.

Last Tuesday, while many of us were casting our votes in the presidential election, the Federal Communications Commission (FCC) was making a landmark decision of its own. On their private ballot was a proposal to open the so-called “TV White Spaces” of the frequency spectrum for expanded use. And on November 4th, the proposal passed. Sounds all fine and good, right? Well, maybe not. If the FCC’s current plan goes through, it will lead to a crossroads for the wireless microphone industry and for AV designers. (more)

Are OSHA Earplugs Enough?

Kenric Van Wyk | Industrial | November 6th, 2008 | 1 Comment

OSHA, The Occupational Safety and Health Administration, has long had policies regulating noise in the workplace. Their “Hearing Conservation Program” is designed to protect workers from suffering hearing loss even if they are subject to loud noise exposures over their entire working lifetimes. But navigating the waters of OSHA’s 1910.95 Noise Exposure Standards document can be a difficult (and daunting) task, and many industrial facilities are happy to outsource this task to the nearest hearing protection salesperson. Unfortunately in this case, ignorance isn’t bliss. (more)
