How Weather Affects an Outdoor Noise Study
For many years, I worked as an acoustical consultant in Southern California. We had seasons in SoCal, but it took several years before I easily recognized the subtle differences between summer and fall or between winter and spring. Summer brought daytime temperatures in the 80’s while wintertime temperatures tended to range in the upper 60’s. But for the most part, the temperate climate meant that days would be warm, dry, and sunny and nights would be cooler, dry, and cloudless. My point: long term monitoring of outdoor noise levels and sound propagation was easy.
After ten years on the West Coast, I returned to the Midwest to work for Acoustics By Design, Inc., and found myself back in the midst of weather – real weather – blizzards, sticky summers, and thunderstorms. Most people know that weather can influence sound propagation, but by how much? (more)
“…You can’t handle the truth!” If you’re a movie fan, then you probably recognize this line from the 1992 blockbuster, A Few Good Men. Of course, Nathan R. Jessep (Jack Nicholson) delivered the line in response to Lt. Daniel Kaffee’s (Tom Cruise) questioning in that tense courtroom scene. But in the real world, what happens when a loud outburst like this takes place…in a Courtroom, in a Judge’s Chambers, or in a Jury Room? How is that sound stopped from transmitting into adjacent rooms and hallways? The unfortunate truth is that in many cases, it’s not. (more)
Medlar Field at Lubrano Park in State College, Pennsylvania isn’t just the first LEED Certified ballpark in the world – it’s the only one (to date). Known as “The Med”, the new ballpark raises the bar in “green” sports facility design in several areas: water conservation, waste management, and recycled materials. Acoustics By Design first learned of the ballpark’s achievement while attending the MAPPA conference at the Monona Terrace Convention Center designed by Frank Lloyd Wright in Madison, Wisconsin.

I worked for years in churches as a Technical Director, and during my tenure in that position I had a front row seat on the effects of volunteer-installed equipment. While there is a time and place for volunteers to do some elements of installation, let me say that it’s generally a bad idea. Not because volunteers will always get it wrong, but because volunteers are too valuable to compromise. Here are a few observations/experiences from my years in the trenches. (more)
It’s interesting to watch the broader culture around us as it adapts to new ideas and theories. The “Green” concept (the idea that we need to take care of the environment, reduce our carbon footprint, save energy, etc.) really isn’t new at all, but the mounting “buzz” around the word certainly is. When I was growing up, green was nothing more than my favorite color, but now it’s a top story in the news, a popular ad campaign, even a way of life. (more)
