> Holderied says it could be possible to make materials ‘10 times more efficient at absorbing sounds than what we are using in our homes and offices’. Think sound-absorbing wallpaper, not panels, he adds.

I would love to have something like that. All these open floor plan offices and open concept homes are loud AF.

There's a catch for a moth fur farm startup though (plush might work better):

To use in construction one must have to answer some very difficult questions like how well does the material survive dust and the cleaning process? How long does it last by itself? How does it interact with the other constraints like fire resistance, allergies, etc?

And after all that, filtering low frequencies is still a hopeless task.

Not to mention flammability of the material.

[zeristor]

One does have to consider the frequency, I’m assuming dampening high frequency sound is easier than low frequency.

As someone who's lived under an inconsiderate asshole who would play loud bass heavy music at 2-3am. Yes, low frequency sounds are much harder to dampen. Especially when they shake your roof and walls.

After listening to best softies of the 80s for 3 hours from my neighbors walls, yes please.

I also play guitar so to have a “jam box” would be great. Like a vocal box where you’re isolated but for really REALLY loud guitars.

[RileyJames]

That’s a thing, primarily used for recording, but your use case would work.

They’re called isolation boxes, easy enough to DIY build one.

[gabereiser]

Yeah, exactly, but I want to be in there with it cranked to 11. I need to build a bigger box.

[orliesaurus]

I would love it around my place, on the walls, no more loud neighbors would make this place paradise!

Hanging sheets of foam-backed mass-loaded vinyl might help. But maybe not practical :)
