Does anyone know of any research which shows the varying kinds of sound insulations including Fiberglass on the absorption or lowered transmission of harmonics and harmonic distortion, and especially broken down into even ordered(2, 4,6,8,etc) and odd ordered(3, 5, 7, 9, etc)? Pinky

Why? Fiberglass and other materials are permeable to different frequencies at different rates, so their damping characteristics tend to vary by frequency. In electricity, odd ordered harmonics tend to produce more heat than even ordered harmonics. And Fiberglass absorbes more heat than fiberfill. Is this your opinion, or is there measurement data to suggest this to be true? Pinky
