When the founders are also the lead engineers, incentives are aligned. I asked the Ableton CEO at multiple events and expos to fix repeatable bugs, and add proper PDC, and he mocked me.
I'm a mix/master engineer, and I just skimmed the paper to look for attenuation potential of this new material. It looks like they only tested above 100 HZ, which is still alright for conversation, but not for professional recording studios.
As you can imagine, the low frequency attenuation isn't great. But the performance of higher frequency attenuation is pretty good. I think this material would work well for meeting rooms, and perhaps restaurants. Not for recording studios.
