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.
Students at the Frost School of Music had an “ear-opening” experience when their Computational Psycho-acoustics class was lectured by Jim DeGrandis of Acoustics First last month. The topics ranged from engineering to human perception of ultrasonic frequencies. The students were exposed to concepts and demonstrations of ultrasonic frequencies which have been modified in ways to make them audible, and ultrasonic anomalies affecting the audible range in ways that are very blatant and obvious.
One of the most stark examples of “audible ultrasound” being the demonstration of a Parametric Speaker, which modulates the ultrasonic carrier to produce very directional audible frequencies.
Jim also spoke at the student forum about misconceptions of what it really means to be “in the industry” …and did an encore demo of the Parametric Speaker – which had apparently been such a novel experience for the Psycho-Acoustics class that they ‘demanded’ it be experienced again by a wider audience. (and it was just plain fun!)
With all the Diffusers on offer from Acoustics First® these days, this gem is sometimes overlooked: the QuadraPyramid™. Here’s an install pic of a few in the ceiling of a control room at the University of the Pacific!
There’s a reason why various pyramidal diffusers have been used for decades. They work, and they work well! The QuadraPyramid™ is our own take on this classic design, using four offset pyramids to create 16 angles of reflection on a single unit. Also, when mounted directly to a wall, these diffusers can double as a ‘mid-bass’ absorber, like in the project studio below.
Cloudscape® Baffles are a wonderful product! This batch of baffles was installed in a middle school gymnasium/multi-purpose room by one of our dealers. Note how they were installed not just in the ceiling, but also on the walls by ‘chaining’ the baffles together. Most of the time we recommend hi-impact Sonora® Panels for the walls in school gyms such as this, but with a little ingenuity baffles can also get the job done!
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.
