Renovating a broadcast studio is a daunting task – technically, financially, and logistically. Amidst the chaos, it is possible for certain things to fall through the cracks – even important things. As the student run station at NC State University began their renovation, they were focused on doing it right, and not letting important elements go unaddressed.
When Jamie Lynn Gilbert, the Associate Director of Student Media and Adviser to WKNC 88.1, contacted Acoustics First they were finishing up an extensive renovation of the HD-2 studio and were looking for some Sonora® Acoustic Panels as the “final touch.” The end result was the frosting on the cake of this renovation, and the impact, both acoustically and aesthetically, was quite evident – even to their consulting engineer on the project.
So evident, in fact, that just a month later, Jamie was back in contact with Acoustics First® to get nearly identical treatment for their production studio as they completed its renovation as well…
“A panel mounted to the wall is a panel mounted to the wall… right?”
This isn’t entirely accurate, and we are going to focus this installment on the often misunderstood Stand off clip.
What makes the Stand off clip different is that it doesn’t hold the panel flush to the wall, but it leaves a gap between the wall and the panel.
Why would you want this?
There are a few very important reasons, both acoustic and aesthetic.
Sound travels around all exposed surfaces, and by raising the panel off the wall, you expose the back surface to sound, more like a baffle, which is a great absorber. Also, sound will pass through a panel into the space behind, bounce off the wall, and then have to pass through the panel again. This transition from panel to air and back changes the medium sound must travel through – this effectively changes impedance, which strips energy from sound. These are just a couple of the acoustic benefits of using a standoff clip – there are others.
Wall mounted Sonora® panels take on a whole new dimension when using Stand off clips – they appear to float in mid air a couple of inches off the wall. This alone adds visual interest to a standard panel, but it can then be further accented by back-lighting the panel – changing the simple panel into a focal point in the lighting scheme.
When Acoustics First® was approached with the ideas for the Main Hall of the Kentucky Center for African American Heritage (KCAAH), they needed acoustic materials that would not only work to acoustically tame the large space, but to have some be the focal point for attention – while others needed to blend in.
Aukram Burton of KCAAH wanted to have large portraits of civil rights icons, not only nationally, but paying particular attention to leaders with a connection to Kentucky. He also wanted to have large panels with quotes from these figures. These would be a custom printed Silent Pictures®/Sonora® Baffle Hybrid – with a 1″ Custom printed Silent Pictures® panel on one side, and a grey fabric wrapped Sonora® Baffle on the back. These would maximize sound absorption due to all of the surfaces being exposed to sound – while being aesthetically significant to the space. Their sheer size presented some technical challenges – with the portraits being 4′ x 8′ and the quotes being 4′ x 10′ – creating custom artwork on this scale required many technical consultations, as many photographs were not easily scaled to this size.
They did not want the other treatments to distract from the portraits, so they chose to install large Cloudscape® Baffles in a gray material that closely matched the gray color scheme of the support beams, trusses, and HVAC elements that are exposed and prevalent in the hall. This allowed the large 4′ x 8′ baffles to blend into the background, while still taming the acoustics of the large hall. The acoustics make the hall feel like a much more intimate venue than its imposing size suggests.
To get the full effect of the visual impact of the space, Aukram sent over a video tour of the facility.
Hidden Creek Home Owners Association contacted Acoustics First® to remediate the poor acoustics of their clubhouse meeting hall. Hard surfaces and tall ceilings contributed to excessive reverberation and poor speech intelligibility. The HOA board wanted to address the acoustics of the meeting hall during an upcoming renovation of the space.
Hidden Creek HOA submitted pictures and plans of the clubhouse to design consultant Cameron Girard. After calculating the amount of absorptive treatment needed to obtain an ideal reverb time, he submitted a treatment proposal with Sonora® panels that would ensure a significant acoustic improvement. Cameron provided detailed renderings to the board, allowing them to better visualize the layout of the panels as they reached a final decision on treatment.
A single skilled contractor installed the panels in a few days, leaving Hidden Creek residents with a much more suitable acoustic environment for meetings and small group gatherings.
Here are a few pics from a job in New York which was installed a while back by one of our regular dealers.
Note how they used a nice mix of 2’x4’ and 4’x4’ Sonora® Panels to work around the geometry of the room! Spreading around a bunch of smaller panels, like 2’x4’s, can work great because of the flexibility it gives you with your layout and design options.
