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?
