This sound-suppressing silk can create quiet spaces

Titanium and rhodium are both high velocity materials and make the sound much more reflective. Cryo treatment would make those 2 materials more linear but still way to bright. Silk by nature is very low shear and low velocity.

I wonder if this material might be suitable for loudspeaker baffles?

It seems the possibilities are endless.  How about using it to block the infernal snoring of one's partner.  Now all we need is for someone to roll out the product.

Some have commented it might be very expensive. Perhaps. But if it became standardized and developed as a building material, audiophiles would benefit the way we do when we make our own absorbers, now.

Thanks for the tip. Google search lead me to couple of vendors selling soundproof curtains. It will be an interesting experiment to hear the result of combining these curtains with my existing GIK’s Gobo panels.
