I cant say that GIK or RT are using membranes on anything but you do make a point in regards to Foam.
Foam is efficient at certain frequencies as you state.
I believe folks here see the low-frequency issues to be of higher importance primarily due to its existence in a standard designed room in most houses which most of us record in.
My big AHA moment in all of this was to equate sound-waves with thermal energy.
That made a big difference as to how I look at absorption.
That is true but often times the one thing that is under rated is moving the listening position. Even a few inches can make a much much bigger impact than even a substantial amount of broadband absorbtion. If someones in a bad spot and won't move its arguably a waste of time to even try to tackle acoustics in a small room. One of my wall to ceiling (16' long) corners was filled with 13" of faced fiberglass/sns insulation and for aesthetic purposes i covered it with 2" foam and it made a big difference it got me thinking maybe as a system this foam can work better than on paper? The reduction is consistent in different areas of the room. *edited to prevent a flame war*
