BXI Thickened Sound Absorbing Panels - 12 Pack 12 X 12 X 0.5 Inches Dense Acoustic Panels, Echo Noise Reducing Sound Panels, Tackable Studio Panels for Wall and Ceiling Acoustic Treatment

I've been working from home since pandemic, and I share office space with my wife. We both have meetings, so you can imagine the noise! I first tried a moving blanket (those thick blankets movers put on pianos and furniture to protect them). Hanging on the wall, it helped a lot to cut reverb/echo in the office.We moved the office into a new room, and I took the opportunity to use real sound treatment panels - so I tried those. They work really well - and they do what they promise:- They cut on ringing/reverb in a room. Clap your hands loudly in the middle of the room you want to treat. You may hear metallic reverb. These panels help to cut that tremendously. Music also plays much more cleanly, especially at higher volume from my studio monitors.- They do not expand or smell. They smell nothing and are ready to apply right away after unpacking.- They weigh next to nothing: you need 3M command strips to hold those to the wall. Two small strips work wonders, and unless you intend to do a mosh-pit in your room, the panels will stay on the walls. For ceiling application, you definitely need more double-adhesive.- They do NOT make a wall or door soundproof. They cut down the echo/reverb and cut a bit on sound, but that is NOT their purpose to soundproof.- You need a lot of these. I suggest you search online for "sound treatment calculator" and you will find plenty of websites to calculate how many panels you need to cover your walls/ceiling. I bought three packs of 12 for a medium room. I may need more to treat the ceiling.- You CAN get mostly the same effect with those moving blankets. It's probably not that much cheaper, just a lot uglier.

Si lo que deseas es reducir el ruido de una habitación esto no te ayudará, pero sí reducen el eco que es para lo que está diseñado.

Estos paneles vienen de buena calidad, los monté en mi área de Televisión y ayudó mucho con el eco, no tienen ningún adhesivo pero con las tiras adhesivas apra pared se pegan perfecto.

Buena solución sin complicarse, no esperen aislamiento total pero de algo sirven

does not stick very well, had to add more adhesive
