bass traps

I've found a curious phenomenon in the measurements of the "Trapping Traps" experiment on Gearspace The experiment was conducted by placing various configurations of bass traps (porous and VPR) in a 4.055m x 3.13m x 2.26m room, and measuring the decay times at low frequencies. The room has...

Hello all! Hope all is good. I have already posted a thread asking for help setting my listening room/closet before i got ny speakers. But when i got the speakers (Genelec 8361a) I experimented a little with placement of speakers and furniture and I think I did a pretty good job getting my room...

What is the proper procedure for measuring the absorption coefficient of an acoustic panel? I've been making DIY panels for a bit, but just broad band velocity traps made from either fiberglass or rockwool insulation. I want to start making tuned bass traps, Helmholtz and membrane traps. But...

Several months ago I built and installed 4 bass traps to my living room, each of them sizes W60cm x H72cm x D10cm. I only used variable smoothing when I measured my speakers (ELAC DBR62) when I installed bass traps, and thought that they made some positive changes. I posted FR graphs on reddit...

Hi, Does anyone have any experience or Isowall wall damping or any similar? After watching it seems to make more sense to damp the walls instead of stuffing a room full of room treatment. For my new house I was wonder if it's worth the effort to do something like this. The house would be a...

We may soon have sonic wallpaper with microscopic scales that help absorb sound. Now, how effective it will be will need to be seen.

I'm planning to build some bass traps. The rear wall will be treated with about 40cm of glass wool but I want something more attractive for the front wall. I really like the looks of triangular bass traps; they're not as visually intrusive as square bass traps to me. I do all my caculation...

Recently I have upgraded the HT/listening room with acoustic treatments. Now, the REW measurements show 100-400Hz region decays faster than the 500+Hz region. Also something strange is happening around 50Hz and 85Hz. The REW experts here - would you mind having a look at the REW measurements...

Picture: Yeah, so I really don't have anywhere else to place the speakers at all. Will I get a big improvement in sound just by putting bass traps on TOP of my subwoofers. I really don't have anywhere else I could put them.
