Shiva Posted October 28, 2020 Share Posted October 28, 2020 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. 👍 2 Quote Link to comment Share on other sites More sharing options...

babadono Posted October 28, 2020 Share Posted October 28, 2020 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. 2 1 Quote Link to comment Share on other sites More sharing options...
JohnA Posted October 29, 2020 Share Posted October 29, 2020 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.
