Sound Absorption panels, Made With Towels.

[Shiva]

For anyone who has read The Hitchhikers Guide to the Galaxy, the most important item in your travel kit, would be a towel.  This guy tests out a few simple items for some DIY sound absorption panels and found that the towel works best. 👍

there's a reason they use Acoustic curtains in theaters. fabric does a great job.

Sound transmission(from one area space to the next) or absorption(the stopping of reflections back into the space where the sound came from)? They are not the same. A 6" thick slab of concrete between his source and microphone would measure better in his test.

Babadono has a good point, but a DIY tester would have some trouble separating the direct sound from the source from the reflected sound from panel.  I believe the test is sufficient to identify differences, because sound will pass through the panel to the wall and reflect back through the panel into the room.

 

I devised a panel design with A/C duct board, but then never built them because, curtains, carpet, furniture and acoustic tile made a dead room.

Or he could of just moved the microphone a couple hundred feet from the speaker.  Isolation ftw!
