Wall made of CORK

I am actually redoing a refresh to my listening room that is 23 X 23 ( irregular)... I am planing to put an entire wall made of cork ( pieces of 12 inches by 24 inches , 3/16 thick). First of all, this is for esthetical reason and the second aim is for accoustical reason. My main concern is if I should put the cork on the wall behind the main speakers or on the wall behind my listening seat (sweet spot). In the back ( behind the sweet spot) there is an open area that stands 10 feet wide by 4 feet deep by 16 feet high that is the cage of the stairway (ceramic). I am at second floor. I was told there will be more benefits putting it in the back wall where i am listening to the music. Note that i have a big shag in front of the speakers. The room is moderately live.

Maybe i could try to be sponsered by Budweiser or by Le Château Mouton Rothschild for this costly project ...

Thickness is what matters. If you can get a rough textured surface it may also help. I have a room with cork floors and it is actually quite bright sounding not much better than regular hard wood flooring (which is not good) - so a lot will depend on the type of cork/thickness - every doubling in thickness will extend the LF broadband absorption. At 3/16" you are likely to only effect upper frequencies and will miss most of the midrange although if you add this to the gyprock wall thickness it may get you some added absorption down to 3000 Hz. For comparison think of how thick a wall to wall carpet and rubber underlay is and how it covers a larger surface of the room - that is what gives significant impact in a room.

My floors were cork through out the house growing up and I don't remember any particular smell except when they were buffed.

Cork has a distinctive odor. A wall of cork will have a lot of it. You've never smelled it?

........... improves voice clarity and channel separation.

1/4 " are better then 3/16".
Try to avoid the cork that is used for sticky note boards and buy wall designed tiles. These are a bit harder, thicker then the board stuff.
These natural cork tiles actually work quite nicely as subtle acoustic treatment.
It reduces the reverberation and liveness of the room as well as voice clarity and channel separation.
No, it is NOT a replacement for designed acoustic treatments but it definitely helps and looks cool...........and it is one of the green products along my other favorite - Bamboo. :)

Cheers and good luck with the remodeling
