Very interesting, Rene,
What if the wall is reinforced concrete?
.... wood struts covered by particle board and painted over?
.... plaster and/or adobe?
.... does wall thickness matter?

In the same room, or separated by a brick wall
If we assume a 10dB attenuation for a brick wall ... then class A
equipment converts into class B equipment isn't it??
