Re: [Sursound] Ambisonic Cube reverberation attenuation with foam
How have you determined that reflections from the room walls are the source of the perceptual problems? To test for that, it might be best to try a temporary fix first. I have successfully used moving blankets to prototype room treatment. If moving blankets are installed away from the actual walls then they are extremely efficient absorbers, even down to low frequencies. This can be done using hooks and twine and the amount of absorption can make the room almost anechoic. Perhaps they can be attached to the outside of your rig. Moving blankets can typically be purchased for $10 each or about $80 for a dozen.

I have encountered reverberation issues with an Ambisonic installation, of dimension 5x5x2.5 meters (a squashed cube, so to speak). I have noticed that reverberation is due to the proximity to the surrounding walls (7x12x6), causing imperfect appreciation of the spatial sound designs when heard in the middle of the cube. Assuming that this is the correct understanding of the problem I was wondering if: - surrounding the cube with the following foam material http://www.anyfoam.co.uk/sheet-foam.php <http://www.anyfoam.co.uk/sheet-foam.php> (the acoustic foam) would significantly reduce reverberation effect to better the definition inside the cube? - where exactly would be best to put the foam?

Would just the sides (excluding floor and ceiling) of the cube be enough ? - should reducing the overall sound power improve the situation? Looking forward to hear your opinion, I would greatly appreciate your help Thank you kind Regards Tommaso -- next part -- An HTML attachment was scrubbed...

Re: [Sursound] Ambisonic Cube reverberation attenuation with foam
Foam will help but you should also include some diffusion maybe some RPG (Random Phase Grating), maybe just some additional furniture - we once tamed a terrible room enough to put on a concert (Assembly Room in York) by upending a bunch of tables and placing them outside the array in a somewhat irregular pattern - maybe even some of the very crude, old fashioned hemispherical diffusers made with "bendy" mdf would help. Also, try moving the array off centre in the room or changing its orientation. Dave P.S. Try looking at these pages for more on diffusion;- http://homerecording.com/bbs/general-discussions/studio-building-acoustic-treatment/diy-diffusors-do-they-exist-207974/ http://arqen.com/sound-diffusers/ On 21 October 2014 06:09, Tommaso Perego wrote: > Hello Everyone > I was wondering if you could please help me solve the following problem. > > I have encountered reverberation issues with an Ambisonic installation, > of dimension 5x5x2.5 meters (a squashed cube, so to speak). > > I have noticed that reverberation is due to the proximity to the > surrounding walls (7x12x6), causing > imperfect appreciation of the spatial sound designs when heard in the > middle of the cube. > Assuming that this is the correct understanding of the problem I was > wondering if: > > - surrounding the cube with the following foam material > > http://www.anyfoam.co.uk/sheet-foam.php < > http://www.anyfoam.co.uk/sheet-foam.php> (the acoustic foam) > > would significantly reduce reverberation effect to better the definition > inside the cube? > > - where exactly would be best to put the foam?
