Acoustics First BLOG

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!

If you prefer to use YouTube – you will find the videos uploaded at our YouTube channel here.

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