Bass Trap

Bass Trap - A low frequency absorber. Low frequencies are particularly difficult to absorb due to their long wavelengths. Bass traps are designed and constructed to absorb these longer Wavesand control unwanted room resonances. Broadband absorbers extending to lower frequencies are often called Bass Traps, imprecisely. The term “bass trap” is counterintuitive since these devices eliminate low frequency room cancellations, allowing bass to be heard.

NRC - defining and choosing proper bass traps

@Brien Holcombe

Hi Brien... :)
I'm looking into some commercially-made traps to improve the room I'm now in ( SonoLite Bass Traps), and I was wondering, if I shot you some NRC numbers, if perhaps you would be kind enough to translate what these numbers actually mean.
This would help me, as well as potentially helping other RO members, or, for those who may be doing an internet search on the topic.

GIK Acoustics Monster Bass Trap with FlexRange Technology (How to?)

Hi Folks. Does anyone know what materials they are using to build these panels and how they are constructed? To me it looks like they are using some kind of vinyl material for the membrane. I would order from them and do my whole studio space, but I'm located in Canada and the currency exchange on top of shipping and duty fees will really kill the wallet for no good reason. Id rather just try and DIY my own and get similar results. Obviously they won't be as good at the GIK stuff because they clearly know what they're doing.

Quantum Acoustic Sound Treatment?

Has anyone checked out this video? I wonder if it's an actual breakthrough or just smart re branding of treatment... I suppose the end result is the most important thing.. If people think it sounds good.. it is.. but it seems like there's some fancy marketing mumbo jumbo going on..

There's some cool listening examples and ideas in the video. Interesting stuff to listen for and pay attention to.

New Acoustic Treatment Material/System- Perfect Absorption?

@Brien Holcombe, @kmetal @Boswell, @pcrecord, @audiokid , ... and anyone else who may be interested:
-
"Physicists at Hong Kong University of Science and Technology have experimentally demonstrated a system capable of perfect sound absorption. Acoustic Wavesgo in, nothing comes back out. At all."

Sharing My Acoustic Treatment Build from Cubicle Wall Insulation!

This story is crazy and long, so I'm going to summarize it. Seven years ago I was able to recover some Owens Corning 703 from four cubicle walls that were stashed in a basement at an old factory job. OC-703 is the bomb for broadband absorbers, as we all know, so you know I was thrilled when my boss said I could have them.

I ended up building wooden frames and stapling in fabric. I stayed late after work and built them there, probably 3 hours a day for 5 days. I didn't actually take any pictures during the build, which upsets me because now I'm ready to share the result.

Question on Sizing Corner Bass Traps

Hello guys, I used to come to this forum like 3 years ago(don't remember my other account) but the thing is I learnt a lot of important stuff and for that I thank you guys.

Now I have a question about corner bass traps in small spaces with 90 degrees angles. Since bass Wavesare really big, obviously there's a minimum for bass trap sizing. What is the smallest size for rockwool-stacked DIY corner bass trap in a small mixing room situation?

I've already did a search and didn't find this particular information.

Thanks in advance,

Marcelo Targa
