New Acoustic Treatment Material/System- Perfect Absorption?

@Brien Holcombe, @kmetal @Boswell, @pcrecord, @audiokid , ... and anyone else who may be interested:
"Physicists at Hong Kong University of Science and Technology have experimentally demonstrated a system capable of perfect sound absorption. Acoustic Wavesgo in, nothing comes back out. At all."

Sharing My Acoustic Treatment Build from Cubicle Wall Insulation!

This story is crazy and long, so I'm going to summarize it. Seven years ago I was able to recover some Owens Corning 703 from four cubicle walls that were stashed in a basement at an old factory job. OC-703 is the bomb for broadband absorbers, as we all know, so you know I was thrilled when my boss said I could have them.
