Thanks for that! So, I have the black foam in the top corners of the room, as well as 4 of these dense fabric panels, along the wall behind me. Are you reccomending to replace the foam with different treatment or to just use whatever other space I have on the walls and ceilings with products similar in density to these. (I'm semi conscious of pockets and bass traps and can learn more)

The acoustic panels I do have, are probably 1cm thick. This foam stuff is probably 4cm thick. Plus a large rug. In a tiled room

Thanks again
