Simulations! Now in stereo – and with absorption!
Posted by Acoustics First in Absorption, Diffusion, Product Applications on December 22, 2016
You heard right – with both ears! (or Eyes?)
The Acoustics First® simulations took a huge leap forward toward more accurately modeling real world acoustic environments in two important areas.
- Ability to simulate Two sources (Now in Stereo!)
- Modeling Absorption to strategically remove energy from a space!
These two additions to the Acoustics First® simulations allow a vast improvement to the modeling of acoustic field development – and, while still in the early development stages, has already been instrumental in advancing the development of systems and products to improve acoustics in numerous ways.
See for yourself: In this most recent simulation, we compare the development of the acoustic field in two spaces with identical stereo sources – one room is basically a concrete box, while the other is a concrete box treated with absorbers and diffusers.

- Absorbers at early reflection points (Note Early reflection in First room)
- Diffusers breaking up specular reflections
- Absorbers constantly removing energy from the space – greatly reducing the overall intensity over the span of the simulation.
- This simulation is only modeling .046 of a second!
We hope you find this informative and stimulating and we will continue future developments of these simulations and try to add more functionality and realism to help all those out there to better be able to visualize the different ways you can affect the acoustics of a space.

Acoustics First® makes sound Visible!
Posted by Acoustics First in Diffusion, Product Applications, Products, Uncategorized, Video on November 18, 2016
As many of you know, Acoustics First® invests a great deal of energy in the development of the science of acoustics. Here are three ways that we are making advances that help people learn and actually Visualize acoustics!
Those interested in sound diffusers have certainly noticed that Acoustics First® has produced a Diffuser Data book, containing all kinds of test data about how our diffusers contribute to the sound in your space. This information is a great advancement and we have worked closely with the ASTM committee developing this test method. Some people wonder exactly how the test produces the data that we report, and we have developed a simulation to show exactly how the sound energy is sampled during this test.
If you download the Diffuser Data booklet, you can see a picture of the gigantic test arc at NWAA Labs which is used for the real world tests.

We have also made leaps and bounds in using simulations to show the different ways that diffusion develops in a space. Depending on the type and placement of the diffusers you install, the diffuse field will develop at different speeds, at different frequencies. We can now show a couple of simulations of the development of a diffuse field to help you visualize how sound moves in room without treatment and with two different sets of diffuser treatments.

Bonus video! Imagine being able to see the Untreated room and the Model D room from a different angle – To be able to move around the outside of the room and see how the sound field develops from a different perspective. Imagine no more! Here it is!

We hope these helped you to “look” at acoustics in a whole new way, and stay tuned – more advancements are coming soon!
