i might be missing something but would these work for acoustic pannels?

i see acoustic pannels all over the place online that are painted to look like artwork and i came across these canvas paintings on amazon and i was wondering if i could back them with rockwool to the same effect or am i missing something?

please feel free to chime in with thoughts about this prospect, it seems like it could be a less expensive way to achieve the same thing

I guess you could. But, I wouldn’t expect a huge or really any change. For acoustic panels to be effective they have to be thick and have an “air pocket” between the wall and the sound absorption material. If you look at Roxul our OC703 you can see how thick they are. Some people double that.

Mine are 2” thick with an air space 1.5” off the wall. They’re really easy to build. Just takes a little time.

my thought was to basically extend the sides back with a fabric covered frame to achieve necessary depth

their are many recognized award winning pros in the industry that would argue that 2 inches directly on the wall is fine. And you mix absorption up with reflection and diffusion. The recently completed CEDIA showcase demo theater is one example.

Wouldn’t the canvas reflect most of the sound? I thought we were using spoonflower and the like because you wanted a material that sound would pass through and then be absorbed by the insulation behind it.

yes, that and if it is thick paint it will reflect. I doubt at that price neither the canvas nor the paint is thick.

Thinking no. Likely too tight of a weave, and with the paint you are bouncing back more than you absorb, like others said.

There is a thread in the dedicated area about printing your own acoustic panels. In that case it uses fabric that breathes enough, that after being printed on still seems to have benefits. Might look into that thread. Might be able to find the art somewhere online and use it as well. Ideally it is free use, or cheap use if it's on an image site.

edit: looked up the thread, see here:
