BXI Sound Absorber - 400 X 300 X 9mm 6 Pcs High Density Acoustic Absorption Panel, Sound Absorbing Panels Reduce Echo Reverb, Tackable Acoustical Felt Tiles for Ceiling and Wall Decoration

Item wrapped around pipes to stop noise work okay

I put these up with heavy-duty velcro as this is easy and never falls off. I was really impressed. I brought these as fill in gaps for larger custom made acoustic panels which haven't arrived yet and I noticed the difference in echo straight away. I could have probably saved myself a lot of money and just brought the larger ones ?? Anyway I am so impressed I have ordered some more for a joining room. Highly recommended! Great budget option that actually works.

This product - at the price - does an exceedingly job at what it's designed to do. That is to absorb mid to high frequencies being reflected within the room, not sound proof from noisy neighbours. The reduction (in reflection energy) is both audible and measurable, although that is after coating a smooth concrete wall - probably the worst starting point. I wasn't too worried about colour (I bought it for sound control, not aesthetics) but the 'camel' does blend rather nicely with a light sandy/linen-coloured paint. It says that glue isn't provided and it isn't; I used 'spray mount' glue and, well, they glued and are still glued!

High quality

The product works it just hasn’t stopped the noise transference as we think noise is travelling through ceiling. It has dumbed down reverberation in the room so it does what it is supposed to.
