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!)
Acoustics First® Sound Channels® wall fabric has been named a ‘2015 Top Product’ by Christian School Products magazine!
This article from their November issue explains why:

On many occasions, we get asked about common ways to treat a wall (or walls) either for broadcast, podcast, or other voice recording scenario – where they not only want to tame the reflections within the room, but also block a certain amount of sound coming into – or leaving the room.
Budget is frequently an issue, major construction is usually unwanted, but effective results are always required.
We’re going to show you how to handle a room upgrade – cut down on the sound transmission and cut the room reflections – all with the same skills required to hang high quality wall coverings! Let’s see how you can cover a wall with BlockAid® vinyl sound barrier to block unwanted sound, then go back and cover that with an absorptive layer of Sound Channels® wall covering to finish it off!
This treatment is not recommended for renters, as this is not an easy upgrade to undo. However, if you have an extra bedroom you are using as Podcast studio, this is a great way to treat it… Let’s get started!
Good job! Now, take a breather while that dries, and notice how much less sound is passing through the walls. This is when you will notice that the sounds are now coming from under the door, and through the leaky old window. These can be taken care of in different ways…. but the easiest way is the same way you deal with keeping the cold out! Get some weather strip, a door skirt, seal the gaps around the frame of the door, and windows, maybe go out and buy some heavy curtains for the windows… if you have some leftover BlockAid®, you can always get some Industrial Velcro and temporarily stick a piece over the window!
Installing Sound Channels®
This treatment is a common first step in treating many professional broadcast studios – it gives you extra isolation with the barrier and takes the edge of the sound reflections. Many professional environments then go back and add some additional treatments such as bass traps, diffusers, and broadband absorber panels – especially if these studios are planning on bringing in any musical guests.
This isn’t just for home studios. It works great for kids play rooms, bedrooms, home theaters, home gyms, and any place you want to block sound and tame the sound inside the room.
Customize your space as you will, but this treatment is a consistent winner for cost and performance, and is a great way to get started without breaking the bank!

Four score and seven years ago (1926), movies had just begun integrating sound along with the visuals, as Warner Brothers released Don Juan – syncing a 33 1/2 rpm audio disc to the video as part of the new Vitaphone system. The era of talkies had arrived, as did a new era of fake accents.
While we still have those fake accents from the days of yore (and Johnny Depp as Don Juan), we have new technologies to bring us our entertainment – high-definition video on big screens with 10.2 digital surround sound, playing in home theaters that rival the best public theatrical venues.
While we have seen (and heard) the technological evolution of movies to what they are today, we have also seen (and heard) the evolution of acoustics – and the one area I’m going to discuss today is one of the fastest evolving acoustic disciplines – Diffusion.
Diffuser design has come far from the early days of scattering sound by changing the angle of your wall, or the shape of the room to negate, dilute, or diffuse unwanted or undesirable acoustic waves. Today, acoustic diffusers are mathematical and scientific wonders, designed to be elements that are inserted into your listening environment to create an acoustic space that is open and airy.
During this evolution of diffusion we have seen the rise of many shapes; The Pyramid, the Barrel, the Binary Arrays, Flat Panel, 1D and 2D QRDs, and more… a veritable cornucopia of geometric shapes and mathematically produced profiles, which are scientifically sound, but fundamentally, inorganic.
The notes on the instruments we play, are based on math and physics, but the music we play ebbs and flows from the pounding of drums to the smooth bass lines, from the intimate vocals to screaming, and from the heavy metal acts to classical symphonies (with or without a heavy metal act). Diffusers have followed suit, changing their shape along with the changing industry – making advances as new discoveries are made.
Diffusers have become important acoustic treatments in listening rooms, recording rooms, sound stages, and theaters – embrace the diffusers! Embrace the future Don Juan’s and their terrible accents… ok… just diffusers… fine.

Take a couple of products and make your corner into a super trap!
One of the most pervasive problems in recording and listening environments is the problem of bass build up in the corners. If you want to get the most out of your room, try making your corner into a DIY super trap!
Stuff you’ll need:
- 2’x4’x4” (or 2”)Back-Beveled Sonora® Wall Panel (beveled on the rear to fit corners or a standard panel with angle brackets)
- 48” Bermuda Triangle Trap® or 2 PhaseFOAM™ Bass traps (or a 1’x4’x1” raw fiberglass panel hung across the corner.)
- Foam Adhesive
- Sonora® Mounting brackets
Simple installation instructions:
- Use the adhesive to attach the Foam Bass trap to the wall
- Use the brackets to attach the Sonora® Panel across the corner over the trap
Super simple. Super effective.
As simple as it seems, this method of installing these products is an ideal way to get extra trapping in your corners. This solution changes the corner density multiple times as the sound waves pass through it –as well as introduces a layer of air space. This installation method takes the strengths of the two products and has them working together to eliminate that build-up of energy in the corners – it literally sucks it up like a sponge!
This simple DIY project is provided as a way for our customers to learn better ways to use our products and get more value out of the products they buy. If you are looking for more ways to use the products you have, look to Acoustics First for Ideas. http://www.acousticsfirst.com
