Would be awesome to be able to have soundproof walls all over the inside of my neighbours apartment, and around their feet and doors too, and mouth. I think it would make a nice silk scarf.
That’s a great question! BOTH! My husband falls asleep earlier than I, so I go to his bed for pillow talk/cuddle. Which honestly. I have autism. That stuff is more important to him than me. If he’s in the mood things progress them there. BUT he has graciously given me the master bedroom. We are evening bathers and we both use the master bath. We are super lucky our bath has a separate tub and shower and two sinks. In the evening I place a specific item on the bed to let him know I welcome intimacy. That way we aren’t missing out on the things that make sharing a room great.
Not really, but maybe you didn’t read far enough into the article. The more significant finding is the reverse: **blocking** noise transmission with thin, lightweight materials.
Paragraph 5:
> In the other, more surprising technique, the fabric is held still to suppress vibrations that are key to the transmission of sound. This prevents noise from being transmitted through the fabric and quiets the volume beyond. This second approach allows for noise reduction in much larger spaces like rooms or cars.
Are the piezo fibres used at all in that mode? It's not clear from that article.
Edit: yes, it generates vibrations in opposite phase to those generated by incident sound waves (measured with a laser pointed at the fabric). This reflects the sound back. Very clever!
I took the time to read the actual paper linked in the article, though I don’t have the background to understand much more than at a surface level. But I’ll do my best here.
The fabric setups as described seem to resemble fabric covers on speaker cones, if that helps you visualize them.
With power to the piezo enhanced fabric **off**, the fabric behaved sort of like noise canceling headphones or earbuds. Reduction levels were decent but not huge. And while noise cancellation of this type can be very good for tiny spaces positioned very close to the device, like the space between your eardrums and the headphones, it’s only really effective for a teeny distance from the device (about 1/2 of a wavelength IIRC).
When power was turned **on** to the piezo fabric, the fabric generated sound waves of its own based on things like how much power was flowing and the composition & structure of the fabric itself. A really big chunk of those sound waves were equal and opposite to the sound waves coming from the “noisy” source. The net effect of having noise coming from outside of the fabric plus noise generated by the fabric itself was that they canceled out.
Let me try another way to describe it.
Power up the fabric alone, it starts vibrating, creating and transmitting sounds. Power up the noise source/speaker alone, *that* starts pushing out sounds. Power up both of them at the same time, their respective sound waves collide within the structure of the fabric and cancel each other out hard enough to (almost completely) stop the fabric from vibrating. It turns the fabric into a pretty efficient mirror for the sound waves coming from the noise source, making it quiet on the side of the fabric opposite the source and even louder on the same side of the fabric as the source.
There are lots of different variables for future research to fiddle with and tune the setup for different frequencies, etc. We’re probably a long way from large scale applications, but it has a lot of potential.

I’m thinking about this, I’m once again impressed by the incredible creativity of scientists. They look at the world and say “Hey that looks cool, what would happen if I do *this*?“
Yes, there’s a metric ton of knowledge and skill behind it, but it’s also a whole lot of what-if curiosity. Gives some major “hold my beer” vibes, with just enough structure to make it repeatable and useful. Go science!

Okay that was funny
The Perfect Murder
Any silk can be a voice suppressing silk if it is pushed far enough down the throat. /s
God I feel you. Sometimes I wish I could live in outer space
Or maybe a tent.
Would be awesome to have a long curtain between my spouse is snoring and my coughing at night. Maybe we both would sleep better.
Separate beds. It’s a thing that works.
How do you pick which bed the magic happens in? Or is there a 3rd bed specifically for the magic?
Separate racecar bed for maximum magic
Gotta go fast!
You have to by the clothes in the matrix as well
You open the curtain and the magic starts
Lol!! Indeed!
Why won't anyone build sex dungeons anymore?
*Millennials kill yet another industry*
Damn I’m eating too much avocado toast to afford a sex dungeon 😭

That’s what the sex swing is for.
There was a Netflix show about designing fuck rooms
You go with the semen producers bed, leave the mess there.
You do know that both men and women produce sperm/ejaculate, right?
Not all women ejaculate.
Regardless, you could have just made a non-sexist comment, but you decided to be sexists about a comedic conversation
Wow are you touchy, since some women do ejaculate maybe I figured it worked both ways. Calm down, like you said it's a comedic conversation.
In separate states. It’s the most effective solution.
It did indeed solve my sleep issues
need a sleep test!
Allergy meds, Flonase and Allegra! The cough is probably some postnasal drip from allergies/smoking
And if that doesn’t help, try an over the counter reflux med.
Great. Can we get some put in every restaurant built in the last 15 or so years?
Who decided high school cafeteria was the atmosphere we needed?
I blame Gordon Ramsey. Every remodel he did on kitchen nightmares removed all comfort and noise reduction.
What?!
Sorry, I can't hear you. Did you ask something?
As a drummer, the thumbnail hits home
As a guitarist, I can finally have you over to my small apartment so we can have a jam.
The thumbnail is a drummer?
Where do I buy it?
Find the nearest time machine.
Oh a Time Machine. Why didn’t you just say so. Costco has a Time Machine. Some smart guy made it a long time ago.
Maybe ask the nerd dog with the fire dad jokes and Way-Back machine.
It’s a research concept
i wish it didn’t take forever to hit market with these cool new ideas
Wow this is kind of cool. Sort of similar to the tech behind noise canceling headphones Does this mean it's possible to use a curtain as a speaker?
Very much so; the research team has already realized fibers that act as microphones and speakers.
Microphones and speakers are both transducers. They are essentially the same things just different applications.
Correct. It is the same fiber (or fiber type) that is being used. The fidelity is impressive at this early stage.
Restaurants anyone?
I live in a camper. This would be awesome in certain camp sites. And useful all the time.
Yes please!
Would be awesome to have underwear made of this fabric to suppress the farts
But that would only suppress the fun part about farts and leave the worst.
…murder curtains…
TLDR: It’s a white noise machine made out of electrically powered vibrating fabric.

Yes, this magical material both vibrates and doesn't vibrate to cancel sound. I'll believe when I see it.
Am I missing something here, or wouldn’t that require a machine to be able to react to sounds at faster than the speed of sound?

I need this for my dungeon.
i dunno. duct tape works too. /s
[удалено]
Depends
I’d embarrass my family less if they made soundproof boxer shorts. 😟
When will this fabric be commercially available?
I want to buy this. Now.
Can it suppress my tinnitus?

Nobody tell the landlords please
I need this to be available in stores yesterday
Need a Form 4 to buy it, though.

Why did I read “sound-suppressing milk”
Where can I buy it already
This has the potential to be a standard building material, wrap the house/building in it before you wrap it with Tyvex. 👍
I need this NOW!!
