Hey Denis and others,

Having witnessed, on many interesting occasions, light, semi-rigid materials reverberating with the bass signal from a speaker or bass guitar, I have been wondering, of late, how useful a wall of this type of material would be to capture, then resonate and negate troublesome bass frequencies. One medium I thought might work (just a stab in the dark here, as I don’t know nearly enough about it) would be those ripple plastic sheets, usually used for light roofing.. They seem to come in different thicknesses and different rigidness.. If a few were hung by, say, fishing line, and placed a foot or two from the wall, would they not both diffuse, by their shape, and dissipate some of the bass frequencies?

When no-one was watching I held a low note vocally, and felt the panel vibrate. Doing this, is it not absorbing some of the bass energy.

I just wanted to throw this out there …haha…for ridicule or comment. I’d like input on why it wouldn’t work. Would an alternate material work better?

Continuing to enjoy your vids, Dennis. Keep ’em coming.

R, Low-frequency barrier technology is all about mass and density. There is simply no substitute no matter what is said about the topic. People are always looking at easy fixes that weigh and cost less. The issue with lightweight materials is that they only work for frequencies above 100 Hz. Below that, you must use mass with the proper density.
