Best Wood for absorber panels

is there such a thing?

or does any wood work?

is there a better alternative for wood (possibly cheaper) ?

i've seen many brilliantly assembled pieces here by the sluts, which has inspired me to make my own.

Thanks!

MDF and plywood and you will be fine!

Most acoustical panels that are used in auditoria are really MDF with different finishings.

You can use gypsum as well. Another possibility is melamine panels.

It it will be showing, you can use just about ANY nice looking wood. If it is hidden - again, anything that has strength and is economical.

Some have used steel studs effectively.

It depends on what you are trying to do. If you simply need framing for absorption panels, just about any structural material will work. Make it strong enough to support the 'panel's AND anyone leaning on them.

If you are doing wood for diffusion, diffraction, scattering... again, just about any wood will work nicely. Of course I have a great love of natural finished hardwoods, but others prefer painted and the like.

Extremely rough finishes vs. highly polished will sound differently.. but it is often subtle. So don't sweat it too much.

a couple of photos might help... see attached

Cheers,
John

awesome!
Thanks a lot guys!!

and John, those pics look sweet!


I would like to quickly ask... might be very basic and stupid...
but yeah, if i get rockwool/glasswool... for panels/diffusors etc..
should i get the thickest
(the store im looking at is offering 25-100mm)
... should this be fine?
(im guessing layering it would be fine?)


and for basstraps... would it be more sensible to get glasswool thats "fluffy stuff"
so that i can just squeeze in a shit ton of it into a "box" or would multiple
panels of the "rigid board" be preferred?

Thanks!

For diffusors you might need rockwool or not depending on the type of diffusor you build.

For bass traps, 40 to 70 kg/m3 is enough usually. There are several ways to build bass traps keep in mind.

No question is stupid.. and you are smart for asking.
Actually, averaging around 50kg/m3 is the ideal density for a rock wool product for the usual 10 - 20 cm deep traps. If you build a 20 cm trap, you should only use 10cm of the rock wool then fill the back of the trap with regular light-wieght building fiberglass (16kg/m3 - approx.)

Yes. For deep traps, it is more effective to use the 'cheap' stuff. 16kg/m3 works great for this.

Cheers,
