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.

Use this silk material as a cover for bass traps? Win-win

Bass traps do little under 40 Hz where waves are feet long so good luck if you have a noisy HVAC, elevator or whatever running the vibrations
