BXI Sound Absorber - 16 Pack Self-adhesive 30 X 30 X 0.9 cm Sudoku Acoustic Absorption Panels, Tackable Sound Absorbing Panels for Wall and Ceiling Acoustic Treatment

I purchased these units to provide acoustical treatment for some loudspeaker testing. I was somewhat shocked when two, relatively small boxes arrived. These panels are all vacuum-packed to an amazing degree. Opening the pack and giving them an hour or so to return to shape restores their full height.They work very well at controlling reflections on nearby surfaces and would be an ideal acoustical treatment when setting up for home recording, or as in a home studio. Highly Recommended.

I use them as a makeshift bed headboard. They are very easy to install. Strong adhesive. Nice to the touch. Light, yet sturdy. I couldn't say if it helps with the noise because I didn't need too many.The only negative I can think of, is if I wanted to remove them, it might be difficult to remove without leaving residue.

Al ser delgados y autoadheribles es muy fácil colocarlos. Lograron disminuir perceptiblemente los ruidos que llegaban a otras habitaciones.

Definitely helped to dull the sound output

What else can I say, if you need sound dampening panels, buy these. They are gray!!

Cool, but so hard to take them of, they took the paint with them!
