Bests & Worsts Reviews from Amazon

*Note: After a few weeks, there are gaps in the foam. I read another review that had the same issue. If anything, the foam should have "decompressed" or "expanded" not shrunk. Sense the wall that I mounted them on was white so the GAPS are very visible. The job no longer looks professional. This is a cheap product is my final opinion. Dont waste your money. I wish I could get my money back but I cant, so Im going to complain to amazon to see what they can do. Had the foam not shrunk I would not even worry about it. I do not think the 2" foam shrunk, Ill have to keep my eye on them. I must first start off saying that I re-ordered 2 more sets. I only re-ordered because I wanted ALL of the panels in the studio to look the same. After carefully reading the reviews its clear you get what you pay for. 1. Dimensions: The panels are not 12 x 12 and they should stop rounding out the numbers they are actually 11 ¾” x 11 ¾” which makes it difficult if you used a design that required 12” x 12”. They can say that they have not fully expanded and decompressed. But I am not the only customer who also experienced the issue with the actual size. There are slight inconsistencies with the sizes which leaves gaps if you are not careful. 2. NRC Rating: The rating for sound was a 0.4, I really think they are exaggerating or using all of the panels combined. Individually they are very light and not ridged. The NRC rating you want is 1 which means 100% of the sound is being absorption. If this product is at 0.4 that’s only 40%, which ultimately means 60% of the sound is being reflected back into the room. A Good rating for home studios would be 0.65 meaning only 35% of sound is bouncing off the panels vs this product which is 60% or more depending on how you design the room. 3. The title is misleading: The quality of this product is not used for soundproofing which is separate from sound treatment or sound absorbing or sound suppression. Sound proofing is if your trying to prevent sound from coming into a space or prevent sound from leaking out. Sound suppression/deflection and acoustic tuning is if your trying to control sounds within a room. This foam may help dampen the echo effect in a room if placed properly. But this foam will NOT soundproof a wall. Its not possible considering the material and how small they are. The recommended thickness for Acoustic Treatment is 2” but this product is not even 1”. 4. Installation: I used light spray glue to attach the foam to the wall. The pros is that its fast and the color matches my wall paint. The cons of the glue is that it’s a light mist so the glue will be everywhere if you do not cover anything you don’t want to have glue residue on. For the most part the foam attached to the glue fairly well. I didn’t follow the instructions because that would be more messy and I could damage the foam. The instructions says to wet the surface and the foam and wait until it dries then connect them together. Sense the glue that I'm using would damage the visual side of the foam I decided after about 3 panels to only spray the glue on the wall within my measured area. This worked extremely well for my situation. 5. I can NOT evaluate how well this foam will reduce the vibration, and reflect sound or absorb sound. I can update this review after I'm finished. However I am also shooting a before and after video of the entire process. Its clear that the foam has changed the acoustics of the room. However, I also built a sound suppression board myself which may also be helping this product. 6. Overall, I like the visual appearance of the foam. And your paying close to $1 for each panel. I really didn’t think this product would “soundproof” the room. Its only used as an acoustic treatment to help suppress and absorb sound. I ran out of panels only after treating 3 walls. So instead of ordering a higher quality foam with real 12 x 12 dimensions or some other shade of black. I designed to continue the entire room with this foam by re-ordering 2 more packages. At this point its only for aesthetics of the studio. I wont know for sure if the foam actual worked until I'm finished and until I actual play back some music. I gave a low rating due to the actual size of the panels are not 12” x 12”, claimed to be perfectly aligned and because its claiming to be used for sound proofing. It claims to have a 0.4 40% Noise Reduction Coefficient. Which means it reflects 60% of the sound waves. Once I hear the results depends if Ill update the rating. Ive finished the job and you get what you pay for... I suggest using 2" foam instead of using "1 foam. The 2" foam has a higher absorption NRC rating. You want 100%, 65% is good... but 40% is not good... however, along with some 2" foam the overall product worked.
