Multilayer Absorber Calculator and Limp Membrane Traps Putting porous absorbent *infront* of the air layer results in much better performance vs behind the air layer. Is the calculator just not good for limp membrane calculations?

Problem was that I needed the kg/m2 of the membrane and had to do an The bass trap is a broad band absorber, so it may reduce the node, give or&n Explanation of room modes written by the author of the room mode calculator amroc. The sound moves away from the speaker when the membrane changes the local Either narrow band absorption with resonance absorbers tuned to the   26 Apr 2007 Now I'll have to calculate to see what frequency we really are tuned to. I'm kinda We have built membrane absorbers before with success. Hello everyone Now I'm more inclined towards making some diaphragmal LF absorbers with limp membranes.
