4 x home-made sound absorber panels (Brincliffe Edge S7)

These are some sound absorbing panels I made very roughly for a recording project.

Please think carefully before claiming: they're home made so, while I tried to be carful while making them, they do contain mineral wool insulation.

They're each about 1.25m x 0.65m x 100mm. They're made from a pallet-wood frame, containing 100mm of mineral wool insulation (batts). I sprayed the surface of the mineral wool lightly in diulte PVA solution, and wrapped it in gardener's weed membrane before wrapping the whole construction in white winseyette material.

I haven't measured how they perform in any detail, but they had a significant impact deadening echoes in my room around where I was working. Might suit a home studio or rehearsal room?

But like I say, they do contain mineral wool so you're taking them on at your own risk.

Thanks!
