Click the link, look at the graph. It shows sound transmission rising from 400 to 4kHz. Has anyone ever heard sound coming through a wall? Does it sound like this? No. It is the exact opposite- the wall blocks higher frequencies more than lower. Even the graph of a supposedly normal wall is total BS.
Also, just look at the screws. Anyone ever see a drywall screw? Anyone? Beuller? What a joke. Thanks OP, but no thanks.
