Bulky Bass traps are no more!

You can even alter the absorption frequencies by a twist, I haven't found any prices yet but potentially this thing could p00n

 

[SocialNumb]

Interesting. Wondering about the price and if anyone has tried them.

Seriously unlikely to make large differences. The graph has no real world meaning either. In the end they're just WAY too small, sorry people but big wavelengths require big solutions

 

[vespiz]

An adaptation on the theme of Helmholtz resonator?

I'll stick with my traps. Clients would think they're trash cans and stuff their fast food wrappers down the holes.

rofl. me too.





but......... i'm still curious. i have shitty 200hz build up in my tiny room and i am easily teased with any "easy" solution.

I was just thinking the same thing.

I was following a thread over at the Mastering forum at gearslutz where a guy tested them. They made practically NO difference, which wasn't a big surprise. I think the conclusion was that if you put in shitloads of them then you might get some decent result, but it was far from the salvation that Vicoustic seem to want to claim it is.

I came across this also while searching, if anyone cares. It is similar:

If you look at the graph, it's true that the absorption will go low in freq but the quantity of absorption is very small compared to other companies bass traps...

Absolutely spot on.

To add more, 4 inch of rockwool has an absorbtion coefficient of 0.99 at 120hz...

not if they're based on Helmholtz resonators...a little Cola bottle for example absorbs around 185Hz.
Panelabsorbers as well don't need depth but absorb sound energy by resonating in the desired frequency range and transforming kinetic energy (sound energy) to heat.

You're missing out that the amount a single coke bottle will absorb is very small, so to absorb lots of energy at 185hz you'd need lots of coke bottles, which would be a big trap, and we're back to where we started.

I could be way off with that, but that logically makes sense to me.

edit, you're still right, but do you get what I mean?

you should see our rehearsal space...well, no coke bottles, but heaps of beer

actually Helmholtz Resonators absorb quite a bit, so does the coke bottle, but only a very narrow frequency band. by increasing the friction in the bottleneck (putting cloth in it...letting it mold) you'll get a wider absorbtion but less efficiency.

that's why we're drinking all sizes of beer bottles during rehearsal, to spread the resonance frequencies across the board

You're absolutely right. This product is on the verge of home audio mythology.
