I'm thinking of just mounting a thin wooden board with a lot of different sized holes in it on top of the absorbed panels and maybe screw in some leftover wooden pieces. Will this work or is the diffusion too random?
Okay, my room is 525cm X 375cm, but the room is also my living room, so there is a lot of furniture and clutter around. So I'm only going for better and not perfect. I think building those panels from scratch is a bit above my level of ambition. I'd rather buy some premade diffusors, when I can afford them. Should I just hang the panels as is and forget about diffusion for now?
Hi tiggerdyret, I think you meant to post the below to this thread:
"Thanks, I'll look into diffusion for the next upgrade. So I guess my board with holes idea will only make things worse then?.."
I don't think the "Vicoustic" or your board with holes absorber/diffuser will make things worse, I just don't understand how they work and they may not offer "true" diffusion...but that's just a guess. I just think that from all that I can gather, QRD's or similar stepped designs are much more documented and tested than other designs so I would suggest you do your research focusing on them to see if that is what will improve your room acoustics.
