Hey All,

My first post here in the Acoustics Circle, mostly I lurk around and pick up tips on room tuning. Today however I was doing a search for acoustical wall covering for my sound room and came across this interesting little product:

http://www.mioculture.com/store/pc/viewPrd.asp?idproduct=9

Has anyone used or know anything about it ?

It looks kinda cool and is priced right. It may need a little tweeking to work as legit diffuser, but looks to me like it may have some potential.

Feel free to chime in with any thoughts and comments.

The absence of any acoustical data like diffusion coefficients would make me a little concerned about its effectiveness. Given its shallowness and lightweight construction, I would anticipate some diffusion/diffraction effects only in the higher frequencies. However, I'm sure that Robin and Ted will urge you to give it a chance and let us know what you think.

This product was discussed in a past thread....maybe I can find it...


.....Not having much luck finding it....
maybe someone that may have posted about it before will chime in....

The picture may jar some memories...

Chris,

I found the old thread: http://www.audiocircle.com/index.php?topic=37549.0.

I'm not sure if anybody went ahead and used them. So I'm going to leave the thread up and maybe get a responce.

Around 2" thick like that will, at best work down to maybe 2kHz.  In addition, repetitive patterns like that are what you absolutely try to avoid with diffusion.  While it might disperse sound, it won't do so evenly nor will it work well in the time domain. 

True diffusion works to spread sound evenly in both the physical domain and the time domain.

Exactly. Also, I imagine the paper and its cavities will vibrate and add undesirable resonances into the room.

I know that there are many acoustic principles that I do not understand (98%), but would the Mio panels in the OP be dramatically different from some of the products from Auralex? e.g. Auralex T' Fusors.
It does seem from the mio website that they are claiming acoustic properties.

I do posses the Mio PaperForms Acoustic Weave. Though they have been in their original box in my closet for about 1 year+.  I saw them in a design magazine and liked the visual texture. And 12 panels are $35. I plan to make a wall hanging but not expecting any acoustic salvation-even though my rooms would make all you guys cringe!

And the back of the panel is hollow.

cheers, ed

The T fusor is a lot deeper and also works in 2 axis.  There are also verified tests of them showing spatial distribution.  They're a completely different animal.

I'm not saying these won't do anything - they will - in the upper mids and highs but nothing in the 'meat' of the music range and little to nothing in the time domain.  They're better than a flat wall but that's about it.

Gents,

Thanks for the responses. Looks like I might pass on this one.

I just have a question for either Ethan or Brian.

Could this product work if combined with other forms of room tuning ( absorption, bass traps, etc.) ?

Or am I just trying to squeeze too much out of this lemon ?

I imagine your loudspeakers and other audio gear are pretty decent, yes? Likewise, if you want bass traps, you should get good bass traps. If you want diffusors, get good diffusors. Do you see a trend here?
