Hexagon PET Acoustic Panel | 1x1 feet | Pumice | 8 Pcs

I compared a few PET options before choosing this one for the office wall. I was looking for a solution that could soften the acoustics without turning the office wall into a technical-looking studio. The hexagon PET panels appealed to me because the treatment could become part of the interior rather than something I would want to hide. Before ordering, I spent time on the MMT Acoustix website comparing the use case, size and basic installation information. That helped set the right expectation: PET acoustic treatment is mainly about controlling reflections and reverberation inside the room, not creating a complete barrier against noise coming through walls, doors or windows. When the order arrived, the first thing I noticed was the consistency of the felt surface and the cut edges. I laid the pieces out on the floor before fixing anything so I could check spacing and alignment. That small step made the final installation look much more deliberate. Colour consistency was good across the pieces in my order, especially in Pumice. The 1x1 feet format worked well for my layout, although I would recommend calculating actual coverage rather than estimating quantity only from a photograph of the wall. For installation, I marked the layout first and checked the wall surface before choosing the fixing method. Adhesive felt more suitable for my permanent arrangement, while I would test any tape first on painted walls rather than assuming it will behave the same everywhere. The acoustic change was easiest to notice during speech. The room has less lingering energy after a sentence, calls feel clearer, and sharp reflections are reduced. It is not silence and it is not soundproofing, but it is the kind of improvement I was actually trying to achieve. Packaging on my order was protective and the panels reached in usable condition. I also appreciated being able to speak with someone for a practical placement question instead of relying only on generic marketplace descriptions. There were cheaper felt products available online, but I was more comfortable buying from a company focused on acoustics. Once I considered the finish, product information, packaging and support, the pricing felt competitive rather than simply expensive. If I were doing the room again, I would start by identifying the most reflective surfaces, treat a sensible area, listen to the change and then add more only if required. That approach gives a better result than covering every wall without a plan.

This was my first proper acoustic treatment for the office wall, so I started with a simple layout.

I specifically chose Pumice, and it looks balanced under normal room lighting.

My only minor issue was that alignment and surface preparation took longer than I had expected, so I would allow more installation time than the product photos suggest.

My main goal was to make the office wall calmer without making it look like a recording booth. I specifically chose Pumice, and it looks balanced under normal room lighting. The panels gave the wall a more designed, architectural look. The material feels firm enough to handle during installation. The surface texture looks professional once installed. The website made the size and application easy to understand. The edges were clean when the panels arrived. The design adds texture without making the wall feel too busy. For anyone confusing absorption with soundproofing, this is treatment for the sound inside the space rather than a complete noise barrier.

The room had a noticeable echo, so I tried a partial treatment first before adding more panels. I noticed this most during late-day team conversations under normal use.

I used these in my office wall after struggling with a fairly reflective room. I needed more coverage than i first calculated. The support team was polite, but the overall experience still fell short of what I expected.
