TONOR 4-Pack Bilayer Acoustic Panels Large Self-adhesive, 47.2” * 23.6” * 0.72” Adhesive Wall Panel, Large Soundproof Tiles for Echo Absorbtion, Acoustical Barrier of Polyester Fiber, Black

The panels look amazing the installation was very easy, it really attaches to the wall easily, the size and thickness was perfect, is a good quality product, good thickness and overall a great addition to the room, would definetly recommend, the acoustic properties help also.

These panels are excellent. They are thick and really help to block out noise. I installed them in my bedroom to reduce the sound coming from a noisy vent in my bathroom that can't be turned off. The noise is now much less noticeable. The panels also adhere to the wall very well—the adhesive on the back is extremely strong. Just keep in mind that once you stick the panel to the wall, it’s difficult to remove.

The focus of this sound deadening is to shield from my laundry room. Water filling and then agitating from the washer is significantly reduced. However I should note since this is a typical utility room of an older home it is asymmetrical. I had to fill a 2'x4' hole with Dynamat (hood liner and dynapad). This then is placed on either sides of the hole. On my room side and the utility room side. This material is being placed on my room wall and the utility room. It isn't complete yet and I have other areas that to finish off.So far I have found a significant improvement. At least 50%. But I have other areas where sound my be coming in. What I like about this material is the cost per sq foot seems to be the best for what I have found on AMZN. You should see an improvement from noisy apartment neighbors, or a partner's instrument practice. It won't eliminate it but is will probably just be a comfortable soft background noise.What is also nice is that it "should be" easily removable and "shouldn't" be too damaging to apartment walls and sacrifice a damage deposit. I would use a hair dryer or heat gun and soften the glue to remove.The material is very tough but somewhat easy to cut. It takes some effort but I can cut it with a Swiss Army Knife. I didn't have a utility razor knife on hand. I measure and cut from the flat back side first, which is the easiest.It is also pleasant to look at. the white/offwhite ribbed material would make a room pleasing and not distracting. It seems tough and durable enough that you could tack pictures to the raised ribs. Even small or medium picture frames, but don't quote me on it just yet.They are very good, but not "professional." Meaning for true sound isolation you need a lot of insulation professionally installed.I am very happy so far.I have just finished, or nearly so, my project. I finished what I could on my laundry room side and room side. The Laundry still has an open ceiling and joists to my room though I have stuffed it with material what I could so far . My room side the joists are covered with these panels as is the wall that I described above. I have also covered all but about 2 sq feet near the ceiling on the wall opposite of my furnace.Audibly I can tell a noticeable reduction when running the washer, dryer and furnace at the same time.Accousticly with my PodTrak P4, Shure SM7B and Chaotica cover I just pick up a whisper of all at around 7.25 gain. At 7.5 I see the line on the meter show, so visually it is indicated. at 6.75 or 7 I can just hear it with my JBL Quantum 100 headphones but my volume on the headset is turned up pretty high and so is on my Podtrak. I hear the white noise more noticeably, the shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh and it just is detectable through the headphones. I would note I can still hear everything in the back ground audibly externally over anything that comes through my headphones.If my gain is set to about 5 I should be able to record anything I need without picking up anything else. But my voice isn't what I would like. I need it just over 5, to at least 6 to be what I desire. Which is right on the threshold of picking up any other noise.So yes these panels will work, and would do well for an apartment. They look sharp and with care can install very nicely. Use a fresh box cutter, measure and cut from the glue/paper side to fit and you will be very happy with these in your apartment or sound/podcast room

I cannot express how much of a game-changer these acoustic sound blockers have been! I live in an apartment with thin walls, and my next-door neighbor’s loud music and conversations used to drive me crazy. Ever since I installed these panels, my peace and quiet have been restored!Superior Soundproofing & Noise Reduction• The panels effectively absorb sound and block noise from traveling through the walls.• I immediately noticed a huge reduction in outside noise, making my space feel much more private and peaceful.• Even loud voices and bass-heavy music are significantly muffled now.High-Quality Material & Easy Installation• The dense and thick construction makes a noticeable difference compared to cheaper foam panels.• The material does not deteriorate or peel off over time.• Installation was a breeze! I used strong adhesive strips, and they have stayed securely in place.No More Neighbor Problems!Since installing these, I no longer have to deal with my neighbor’s noise, and I can finally enjoy my home without distractions. Whether you’re dealing with loud neighbors, home studios, or echo issues, these are a must-have!Highly recommend for anyone who values peace and quiet!

I think the ribbed design will absorb a bit more sound plus looks pretty decent. That said, I intend to mount to the bottom side of a table so I won't see them. Little to no smell!

I loooove these things! They adhere to the wall so easily and they STAY!!! They are well made, easy to apply, and they DO exactly what they say they will! I have a podcast studio which needed sound deadening/absorbing and these do that EASILY!

These are nice and dense, and have great adhesive. They have not fallen off, and they work well for sound dampening.

The sound deadening aspect is just OK. I have an office where I need to conduct staff reviews and its easy to hear voices through the wall. Had hopes of adding this to the office to reduce the transmission of sound through the walls and increase the privacy of the conversations. It didnt really have that affect. It does make the inside of the office feel quieter, almost like one of those hearing testing booths, but it does little to stop the sound from traveling through the walls. Additionally, and this is a big issue. There seems to be no quality control from one panel to the next as far as the width of the ribs. As you can see from the photos it is not an issue of me misaligning the panels, the first rib is perfectly aligned and then as the panel goes down the line the rib width or the spacing is off which causes the ribs from one panel to the next to misalign. I wanted the nice seemless look that they show in thier pictures and had the manufactur process had some guality control, that look could very much be achieved, but this was my result. I even tried to shift panels around thinking maybe if i had some from the same package I could stack them and it look nicer but in the end it dindnt matter almost every panel was slightly different.
