Using cork in acoustic treatments

[cata02]

Anyone used cork when treating rooms?

Noticing official products in this regard, stating it can be used for acoustic treatments, but one specialist recenetly told me cork actually reflects sounds and it's a very bad material for treating room acoustics.

I had an idea of creating a bespoke acoustic panel based off of a 40mm recycled cotton or polyurethane foam and pur a layer of cork on the surface, for the looks and practicality of pinning pictures to it.

Thanks!

The specialist with whom you spoke might be correct:

Good luck!

I just assume/guess if you use 10,000 or more wine corks "randomly" and tightly placed on your wall (and ceiling?), it would effectively contribute to nice sound dispersion, lower the reflection and standing waves, I hope.

My major concern, however, is that you (and your family) could be completely wine alcoholic before completion of your wine cork wall.

Those products look "fluffed up", probably to make it a little absorptive instead of reflective.

Cork is going to reflect most of the mid-range and treble, killing the effectiveness of your absorption material.

An ideal absorption panel has the lowest density material placed first, and the highest density placed last. That way you maximize both the operating bandwidth and low frequency efficiency.

I guess drinking so much wine would definitely solve the acoustic issues for good

serious absorption material will always have laboratorial tests provided
