| Foam is only good for high frequency absorbtion and at 1/2" thickness it will not do anything for low frequencies. IMHO, this will be a waste of wall surface where you could mount real absorbers and perhaps diffusers.
I also doubt it would be possible to glue the pieces together to make a thicker panel. Foam is not the best surface for adhesive to cure and glue.
Also, it's mentioned that the foam is "closed cell type", which is unsuitable for absorption. |
