While acoustic diffusion has become a common acoustic treatment, many people still struggle to explain exactly what diffusion does, or what it sounds like – and because how we hear is subjective – we at Acoustics First feel that the best way to explain it, is to let you experience it.
We have created a demo to let you compare what a room sounds like with no treatment, good diffusion treatment, and extensive diffusion treatment.
The setup is as follows:
- A small office with no windows and one solid door (6′ x 8′- 8′ ceiling)
- Standard office carpet over concrete.
- Drop ceiling with standard 2’x4′ tiles and one 2’x4′ flourescent light fixture.
- Drywall over metal studs – no insulation.
- A binaural head in the center to capture the audio
The demo uses different noise makers to help you hear the room:
1. A Balloon Pop
2. Bang-Snaps (Pop-Its)
3. Slamming a Book Shut
The space is configured three different ways:
While the Demo is best experienced with a pair of reference headphones – earbuds or decent speakers should work as well. The headphones allow you the ability to hear the room just like it sounded when the test was run without hearing your own room – Think of it like auditory immersion. This is the best way (we’ve found) to compare the results of adding high-quality diffusers to an inferior space.
The test is run in rounds, you will hear the same noise (a Balloon Pop, for example) in each room configuration (First Untreated, then with Good Treatment, and finally Extensive Treatment) before progressing to the next round. The image will show the room configuration (and the noise producer in the upper corner) while the sound is played.
The Demo is as follows:
1. Balloon Pop (1 Round)- Untreated, Good Treatment, Extensive Treatment
2. Bang-snaps (3 rounds) – Untreated, Good Treatment, Extensive Treatment
3. Book Slam (2 rounds) – Untreated, Good Treatment, Extensive Treatment
Note: ArtDiffuser® Model D units were the only acoustic treatments used in this demo.
While we would rarely treat a room only with diffusers, the results of treating this space with just diffusers was interesting…
The diffusers reduced the SPL from 89 dB down to 87dB according to a pink noise test with the handy-dandy Radio Shack SPL meter…
Cut the RT(60) from about .7 seconds down to about .4 seconds…
Sometimes hearing is believing.

Acoustics First understands that the Do-it-Yourself spirit in the audio world is alive and well, and here is another one of our contributions to that community.
The personal mic shield… all you need is…
- Foam safe Glue
- a One inch thick, three ring binder
- two 1 foot x 1 foot pieces of foam
- 2 Minutes
Got everything together?
Do you have 2 minutes?
Let’s do this!
Watch the video…
Or follow the steps…
Open the binder and bend the bottom tab flat.
Spray the Binder and the back of the foam with glue.
Wait for a few seconds for the glue to get tacky, then carefully stick the foam to the binder – be sure to apply pressure to allow for a strong bond.
All Done! Just set up your mic and you’re ready to go!
This DIY project is brought to you by Acoustics First – Be inspired and sound great doing it. Enjoy!
Sometimes you enter a space that sounds amazing and wonder what treatments are being used. Many times the treatments are behind the curtain… both figuratively and in reality.
Learn about some of the ways acoustic treatments are hidden in plain sight, obscured from view, camouflaged, or just displayed proudly – Nick Colleran points out the not so obvious.
You just might find – you get what you need.

Season’s Greetings from Acoustics First!
Acoustics First would like to offer this Do-It-Yourself gift idea to all of our readers this year.
If you’ve got a creative painting habit, give a customized gift that not only shows your creative talents, but also helps to improve the sound of the room!
Above is a festive holiday painting on one of our 1’x2′ Tone Tiles™.
Want to go a little bigger? We also have 2’x3′ Tone Tiles™ in Stock.
A Second Idea is to get a photo printed on a Tone Tile™.
How about “posting” that photo to the “wall” of your living room, and have a great conversation piece as well as improved acoustics – at the same time !
Season’s Greetings and Happy Gift Giving!
