UMIACOUSTICS Decoration Acoustic Panels 3 Pcs Flame Retardant Sound Absorbing Panels, 48” X 24” X 0.4” Sound Proof Panels in Equidistant Slot.

An den Bilder kann man sehen das die Ecken beschädigt sind. Dachte das es beim montieren die Ecke sich von alleine repariert. Leider hat das nicht geplappt.

These did what they were supposed to do, cut down on sound reflections in a box-like room. Some were delivered with corner damage and the seller sent replacements with no fuss. To get more from these panels, I mounted them on spacers about 1.2 inches from walls and ceilings and left space between them so sound could also bounce behind them to be absorbed and diffused.

Thank you for shipping 4 boxes so quickly and great packaging. My room is quieter and looks super. I will get more in future.Thank you

I was disappointed in how little the sound changed. I think a thicker or more substantial product would suit my needs better.

The cathedral ceiling in my new garage was an echo chamber until I put 18 of these on the walls. Problem solved!!
