 Also, some of the coefficients change depending on whether or not the sheets are covered with foil. Presumably if stacking then foil is unnecessary/non-beneficial? I notice that higher coefficients do not correlate with higher density - which is better, higher density or higher coefficient or both high density and coefficient? |
I don't know whether it's better to have high coefficient or higher density...All I know is that the "Supertel" does a good job in the configuration that I'm using..

Just wanted to check my calculations to make corner wedges:
My ceiling is 2400mm high
1200 x 2400 sheet = 32 triangles; 600mm (2') across the hypotenuse.
32 triangles @ 50mm thick stacks to 1600mm high
1600mm height x 3 sheets = 4800 = enough material for two floor-to-ceiling bass traps
@ $70 per sheet that's $210 for two traps + covering |
By my calculations you only get 16 triangles with a 600mm face from a 1200x2400 sheet!!
