what happens..... does the soft insulation allow the metal face to deflect low end, thus absorbing it in the process, but not do this at the high end?
to be honest i'm not convinced about this whole claim yet.... |
The theory is that high frequencies will be reflected by the non-porous surface of the foil. Being that the foil, when struck by lower frequencies, will vibrate as a solid "mass"; it effects the insulation on a grander scale.
Someone will be along shortly with a link to proven test results I'm sure.
