If you’re looking to create a quiet recording environment without breaking the budget, a stack of old towels might be all you need.
In this video from the DIY Perks YouTube channel , Matt Perks tests the sound absorption quality of cheap, easy-to-find materials. Perks tested thin, flat sponge, egg holder sponge, two layers of egg holder sponge, a seat cushion, and a folded towel with a spread of 17khz, 13khz, 10khz, 7khz, and 5khz frequencies. All in all, Perks found that a folded towel, either four layers thick or twelve layers thick, absorbed the most of all frequencies. Best of all, you can buy a bunch of old towels at thrift stores for only a few bucks. If you’re looking to build your own custom sound absorption panels, Perks shows you how in the second half of the video above. Industrial Acoustic Panels
