AC lines make sense, although I do not remember hearing about anyone doing that before. Was there any way to quantify the difference it made? Was your Suburban measurably quieter afterward?

That 3m window film would help, but I am much less concerned in this part of Arizona.

Of course, from what I have read, sound and thermal insulation are drastically different; insulation designed for one purpose does little to help the other.
