12 Pack Set Acoustic Foam Panels, 2" X 12" X 12" Acoustic Foam Sound Absorption, Soundproof Sound Insulation Absorbing, Acoustic Treatment Used in Home & Offices

I have been on a journey with these. The instructions say to soak them in water then tumble try on a medium heat or just leave them out for 24-48 hours and they will expand. I don't have a dryer so I left them out to expand. After four days parts of them had gotten bigger but not one had properly expanded. I went back onto the page on amazon and the instructions on there said to soak them for 1 minute and you can use a hair dryer to dry them. So I tried that and they still werent expanding so I started lightly pinching the parts that werent expanding and they started to get bigger. Even though they are now looking better they are still not dry and I'm pretty sure im going to blow up my hair dryer trying to dry them fully. So yes they look ok after alot of hassle but I really don't know if it was worth it. I bought more expensive ones before for my singing room as I'm a singing teacher and I was able to just open them up and pop them on the wall so it was way easier and less time consuming even if it cost a little more. Can't say how they are for use yet as they haven't made it to the wall #stilldamp

Might work for other usage, didn't for me. I tried to use it to block out some of the sounds coming from my neighbour's room, didn't change A THING.Plus they're quite hard to stick to the wall.Pretty sure, useful nope.

Tried several methods to affix these to an indoor painted wall. Not a studio so didn't want to use a chemical adhesive. After several failed attempts, double sided tape seemed like the best solution.

I’ve followed the instructions and the panels have not fully expanded. Some of them are out of shape and dented from delivery or packing Can you please send another pack.

Only 4 out of 12 panels expanded. Tried both methods

Didn’t do much

cant tell the difference from traffic outside on maain road

Spent over £100 on these tiles, hoping to at least dampen some of the noise coming from the floor above (mostly footsteps and creaking). Yet the noise is as loud and persistent as ever; I can't tell if the cladding has made even the slightest bit of difference.

Overall:Got these panels to help my neighbor whos bedroom shares a wall with my office/game room. I can't speak for the sound dampening yet for her since I haven't talked to her yet. But, I can say that from what I've tested they seem pretty good. Nothing crazy, but definitely will take the edge off and help dampening the main waves. I'll definitely be buying more of these since I want to add just a few more.Inflating:I initially took them out of the packs and let them get air for 24 hours or so. They weren't inflating at all, so I decided to try soaking them. It worked perfectly. I tossed three in my sink of water at a time and didn't even let them soak. I just started kneading them to get the packed air out of them. It worked perfectly since it opened the cells and allowed water in them. Once they seemed fully inflated with water, I squeezed out all of the water from them back into the sink one by one. I put them in the dryer for a bit and they were perfect. I didn't have a problem with any of them getting to size.Setup:I kinda wish these came with their own sticker pads to apply them to the wall, but I just used push pins since that's what I had. They seemed to work fine and I'll eventually switch them to picture hanger tabs later. This works for now though. The only thing here was that some where not cut perfectly straight on the edges. Nothing crazy and not workable since all I had to do was smash that side down a little or stretch the other to make it work. Definitely a good quality though since I only noticed that on like one or two. Once again, nothing that couldn't be worked out though. Great quality.

Zuerst war ich sehr enttäuscht und wusste nicht wie ich es auf die angegeben 5cm (komme es kommen alles 12, 5cm Platten auf unter 10cm dicke Vakuumverpackung) mit dem fingern lieber lassen dumme Idee, trocken habe ich keinen! Bügeleisen ist Top um mit dampf die fließen zu erwecken 😄 also ohne damf geht nix 👍👍👍

aunque bastante caras, cumple lo que dice y me encantan

¡Fantástico! Cuando vi que vendían un paquete de 24 paneles por 150 pesos mexicanos, estaba seguro que era un error, pero lo adquirí en caso de que fuera cierta la promoción. Compré dos paquetes. Una semana después, efectivamente llegaron 48 paneles acústicos de buena calidad. Hace unos años compré 4 paneles de otra marca (el anuncio decía que eran 4 paquetes de 5 paneles cada uno, pero era un error. Yo esperaba que llegaran 20 paneles y llegaron 4. Me devolvieron el dinero) y me habían costado 1,200 pesos mexicanos. Estos paneles son exactamente los mismos que debieron llegar en aquella ocasión. Ojo, funcionan perfecto para frecuencias altas y medias, pero NO para frecuencias bajas. Solamente compré cinta doble cara de 3M y ahora funcionan excelente. Mi aplicación es para cine en casa.

Güzel ve kaliteli.
