Scientists Have Discovered a Shape That Blocks Sound

Very exciting discovery:

Scientists have discovered a shape that blocks all sound–even your co-workers

This could be a godsend for hyperacusis sufferers and all of us who have to live or work in noisy environments.

 

Truly fascinating.

 

Here is a link to the paper:

Ultra-open acoustic metamaterial silencer based on Fano-like interference

Here is the press release:

Researchers develop 'acoustic metamaterial' that cancels sound

Press releases are typically over-hyped so I take them with a grain of salt, but it is interesting that they discuss applications for MRI machines.

 

It's been four years and you can't buy this anywhere.

Sickening.

 

There's a good reason for that. Scientifically, it is essentially, physically impossible.
