It doesn't have a strict "X mm" norms but reglaments a noice propagation. Of course it would take some calculation to translate it into millimeters of brick or concrete, but obviously ultra-thin bullet-penetrable walls won't fit into this standard.

I'll trust your translation but now I will ask that you trust that I'm an AV engineer because I don't want to actually do the math.

A concrete or brick wall would have to be twice as thick as a properly-treated wood frame wall for the same acoustic isolation. It would cost 2-3x as much, too, not included drilling for conduit/wires.

[–] username_1@discuss.tchncs.de -4 points 3 months ago (1 children)

Yes. It would cost a few times more. And it will stand for x100 times longer. And it has good thermal insulation. And a bullet insulation too :)

[–] glimse@lemmy.world 5 points 3 months ago (1 children)

Ok, you must be trolling because concrete and brick have TERRIBLE thermal resistance. The same acoustic materials used in a wood wall give it like 20x the insulation.

And if you are not trolling, you should learn more about a subject before speaking on it next time. The claims you are making aren't true

Noise insulation can easily be done without brick/concrete. In fact the normal way is without brick/concrete. These two things are not the same at all.
