Re: Best Sound Proofing Material?
Did you just say their function is to turn vibration into heat?
Dude, it's a mass loader, they're called that for a reason. You ever had something vibrating, like a bell. You grab it and it shuts up, same deal here. More mass = more vibration dampening, it's as simple as that. If you want to get into acoustical dampening that's a completely different area, and is not the function of damplifier, STFU-80, dynamat xtreme, brownbread, or any other mass loader. For that you want closed cell foam normally, and it's for a COMPLETELY different function than mass loaders. If you want to kill ambient noise, you get closed cell foam, if you want to kill noise generated by vibrating panels, you get a mass loader, and more mass is better.
Sure dynamat may be better than secondskin in killing ambient noise, but they both suck at it. If that's what you want to get rid of there are better things out there, and regardless you can get 4 layers of secondskin damplifier for the price of 1 layer of dynamat xtreme, and the ss will deaden better in every aspect. When price is taken into consideration dynamat falls flat on its face. Oh, they also inflate their numbers if you didn't know already. This is according to an independant test, not affiliated with any deadening company at all.
