New metamaterial manipulates sound to improve acoustic imaging

I don't see the application, but I'm not much of a "vision" person.

 

Forgetting the limitations of the material for a moment ("effective for sounds between 1 and 2.5 kHz.") any "improvement" must solve a problem.  I don't see the problem right now as we have materials that can reproduce acoustic sound with both accuracy and volume.

 

The only way I see this stuff being used in speakers is if it could make a cheaper product with superior sound characteristics, maybe in a diaphragm.
