Perhaps, although I doubt if it become anything even closely resembling cost effective in our life time - that's even assuming that they figure out how to make it work in 3 dimensions in our life time......... no easy feat that..........

+1. Will it be cheaper than concrete block for sound isolation?

I suspect its all about getting sound waves to cancel each other out and covering enough of the frequency range to be effective (creating lots of nulls). Looks like the tradoff is going to be square footage which in itself is not going to make it worthwhile for recording studios.

It is not about creating nulls - nulls are destructive forces at play in a room or space - the idea is to stop nulls from occurring, the same is true to constructive forces.........

Well in some ways it looks to me like a gun silencer / supressor or car muffler design on a large scale. The same multichamber with many holes between them type of construction. Those devices work by allowing the sound wave's pressure to be reduced greatly. But what is actually happening in each of those devices baffled chambers other than an increase in volume area for the pressure to drop? Do the waves bounce around more with some of those waves cancelling each other out (creating nulls) in each chamber? Ok, how do you guys see it working?

read the article
It does not understand how RF cloaking works
or else is just making up krapp to put words into electrons.

the only thing that bends light is gravity

RF cloaking bounces it so it does not reflect back strongly
it does NOT cancel it as some other articles claim

This audio stuff is pure bovine excrement
Put enough of anything between you and the sound and it will lower it enough so you cant hear it but it does not erase it

the best sound eraser was at an ibm lab
room had walls covered with pyramid shaped objects made up of dense but not solid "wires" made of something that might have been plastic based and that looked like some materials i had seen years ago in a microwave lab for absorbing mws

walk in that room and it sucked your mind out of your head
it was dead silent
