impressive specs,..but I'm not sure I want something that looks like a shower curtain hanging in my studio..

Hey - these look pretty interesting. I wonder what the pricepoint will be. Thanks for the info Jeffrey. Smile

If the sound absorption coefficient is as reported, that's pretty darn impressive. If it's inexpensive enough, use multiple layers. I wouldn't use it *in* the studio, per se, but it would be great as an underlayer for the curtains in my apartment.

Will be nice for well-healed home theater installs. This stuff can't be bargain priced...

Interesting.

This material will have some good uses, if it performs as stated. In my search I am unable find any data on the test, and what the "typical curtain" is that they are comparing the "new development" to. It's rather ambiguious

It's good to understand that just about everything has some sound absorbing properties, i.e. any incident sound energy that is not absorbed is reflected, transmitted or dissipated.

Incident sound striking a room surface produces sound energy either reflected sound, absorbed sound and transmitted sound.

A good sound reflector would prevent sound transmission by forming a solid, impervious barrier. But, most good sound absorbers allow sound transmission.

Sound reflectors need to be impervious and massive, while sound absorbers are generally porous, lightweight material. This is why a sound absorption will have little effect on preventing outside noise or sound from entering the room. Just ask DB about this.

At a glance the article is misleading, by letting one believe that the material will keep noise out -- It will not, and it can not do that. What it will do is reduce echo and the comb filter effects of a room, while letting the sunshine in.

It will also create a really boomy room by not having any broadband absorption properties.
