New noise canceling material, do you think it will be useful?

[outsidesmoke]

I met a guy at a bar yesterday who was working on this new soundproofing material made for jets. Most dampening material depends on resonance to help cut noise. This material uses something called viscous shear. He mentioned that they just recently found a way to manufacture it on a large scale and the panels would be about an inch thick. I immediately thought that it would have some applications in the audio industry. Do you think it could be used for the cabinets on high end speakers?

Here is an article,

Sure, very useful stuff if it works as advertised.

But it may be best at very high velocities like those found in jet airplane engines...

Also this is a 2008 article, and the person who was the researcher is no longer affiliated with the school...

It might not do much in a lossy material like MDF but on bare metal like the metal frame of drivers or perhaps even metal domes of compression drivers and in suspensions.

It's the same idea as using a bundle of straws to reduce port noise.
