blog of acoustics, noise, vibration & audio-visual systems
Recently we were called in to consult on some highway noise that was affecting a residential community. The state had added a new exit ramp that diverged right through the back property lines of several of the residences. While we talked with one of the home owners, he asked about the acoustical effects of planting more trees and foliage between his house and the new exit ramp. As Acoustical Consultants, this is something we hear all the time: the idea that trees and plants can effectively mitigate loud noise.

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.

In a former life I worked for a very large engineering company with over 1,000 engineers working in an open plan office, everyone working on one floor. We lovingly referred to our floor as the “cube farm”. One day I arrived at the office just as the lunch crowd was making their mass exodus. Although I was frustrated by my inability to enter the building, I couldn’t help but think of the old “how many college kids can fit into a VW Beetle” gag as I waited for the never-ending trail of people to exit the building.
It shouldn’t be a surprise that most companies are decreasing the amount of working space allotted for individual employees. (more)
