14 Pack Self-adhesive Acoustic Panels Soundproof Wall Panels, New Upgrade Proijeut Sound Proofing Padding for Wall - 12 X 12 X 0.4 In Sound Proof Foam Panels Used in Home Offices - Grey

I don't see how it's possible that these added more echo to my room, but it really sounds like it has. Not much, but it's certainly not deadening the room like I expected. I bought two of these packs and the first one seemed to help, but the strange thing happened when I got the second pack on the walls. That's when it seemed like the reverse happened. I'm still working to adjust the sound though. Maybe placement of these panels could still improve what I'm now hearing.

Helped to reduce the echo

These have been great for acoustics, and way nicer looking than the cheaper squishy foam tiles. Plus they don't come vacuum packed so they're ready to go without having to expand them first. All tiles were in perfect condition, and the adhesive was strong enough for sticking to plywood. Also very easy to cut cleanly with razors.

Sound dampening is mild orderd 3 packages for a small room, but majority fell down by end of day the adhesive is so bad, so so bad, had to use 3m double sidded tape to fix

To be honest it didn’t help my problem. I was expecting a better quality. I’m dissatisfied.

I used these in my home "office" (a converted closet) to reduce outside noise and they work great. They successfully muffle any noise from traffic, barking dogs, or lawnmowers and stop any echoes inside the office. They also have the added benefit of muffling my voice when I am on the phone or Zoom, so other members of the household are not disturbed in their work.They are incredibly easy to use and infinitely better than another brand that I purchased. You simply peel the backing off and stick them to the wall. I've found that holding them in place for about ten to fifteen seconds and giving them a firm rub on the front helps them stick even better. I recommend starting in a corner or along a doorway frame to ensure that they line up properly. I installed these on both the wall and the hollow core door of my office and I haven't had a single one fall off despite hot, humid weather in the summer.I also love that these are white so they look very sharp and attractive. I was worried that they would get dusty and be impossible to clean, but I haven't seen a speck of dust on them so far, despite them being up for about six months.These are not soundproof, but they are pretty darn close - they muffle at least 75% of the noise and create a distraction-free office. They're basically the room-wide equivalent of wearing foam earplugs. And, even if I can occasionally hear a muffled bark from the neighbor's dog or a lawnmower outside, the people whom I am on a call with cannot hear it.Overall, these are incredibly easy to apply, stick extremely well, look great, and effectively muffle noise.

The white panels have been on the Wall and never fell off. They and are from a different brand. The black panel is the brand I’m writing this post on. Let the image speak. I have nothing to say more.

Si quieres insonorizar puertas, funciona de forma decente. No te quita el ruido, pero si lo aminora bastante.

Estoy felíz con esta compra porque cumple con su función de insonorizar por ser un material denso. Por el acabado de sus orillas, resulta decorativo. Tiene pegamento de buena adherencia, por lo que es fácil de poner en paredes pintadas. Así que para mí estos paneles son de cinco estrellas.
