Hey Ethan,

I really appreciate your knowledge, humanity and love what you doing best. Although we friends in facebook I wrote this here for all to learn.

I really want to know if you familiar with "stratocell-whisper" product?

How can it be possible that hydrophobic material with closed porous provides an excellent acoustical properties.

From your experience can you explain and verify this.

I attached the link for the brochure:

My purpose is to reduce the reverberation in class room to at least RT60=1 sec using melamine foam or trying this new unknown for me material.

Wish you the best,
Thank for your time,

But you need to be careful with foam or any other material that isn't fiberglass. In public spaces all materials must be fire rated.

I'd like if you can tell us the price. All I can find are quote forms, when I search. It appears to perform much better around 250Hz and perhaps slightly worse in upper frequencies. They treat it with a flame retardant but I still wouldn't smoke around it. If you get some, please let us know how they work out.

Thanks.
