Soundproofing

[lightsource]

Just read this and thought I'd put it up here

Walls of the material could be built to soundproof houses or it could be used in concert halls to enhance acoustics or direct noise away from certain areas.

 

Could be useful in venues where the noise at work regs are a problem.

 

...once it's properly invented of course :** laughs out loud **:

Hmmmm...I wonder if this directing noise away could work on our followspot gallery?!

interesting find. I found this thread in google answers about a different method that is used a lot these days:

I read the article when it came out but I fail to understand how it could be used to soundproof a venue?

 

AFAIU the material works as a cloak, the main principle of which is that it redirects the sound so that it runs around the object it cloaks and appears on the other side as if the object did not exist (man, this would screw up the inverse square calcs!).

 

So, unless you are shielding a venue from outside sounds anything from the inside going out is surely going to be exactly the same.. The only way it would work is if residential properties in the area were treated.

 

That is unless the material can "capture" sound, forcing it to surface run around an object that create the sound until it runs out of energy, but that is crazy talk :(

 

That being said, I'd love to be disproved on this....
