Acoustic Panels 12-Pack Soundproof Wall Panels 12''X12''X0.4'' Sound Panels High Density Sound Dampening Panels - [Gin Green Square]

They work and I like them, but I am having trouble finding a way to keep them stuck to the wall (well actually a door). After reading other reviews, I tried the double sided gorilla tape. It works for a short time but eventually fell off. My next plan is to try to hot glue Velcro command strips to the felt. I hope it works!

I'm using these to replace the old low-density black egg crate foam panels that have been in my studio for many years. The old foam is disintegrating in patches, making a mess every time it gets touched. These square panels are higher density, much more durable, and better-looking in my opinion. I'm sticking them up with double-sided transparent nano tape, which sticks to the walls and the panels very well, if instructions are followed. I'm using nine two-inch long strips of tape for each panel (corners, sides and center). Nothing is coming loose at all. The echo reduction of these new panels seems like it's no better than that of the old panels, but it is quite adequate for the vocal and acoustic instrument recording that I do.

Superbe produit! Attention, les carreaux font moins que 12 pouces.

Label suggested double sided tape like Gorilla tape. It does not adhere to these panels. They fall within 24hrs of placing on the wall, the tape coming off the panel, not the wall. I've since tried hot glue. Haven't found a solution that truly works yet. But the color and quality seem great!

I don't feel like they filter sound as well as described. I could tell a small difference but was expecting more.
