*waits for a smart person to explain what's happening and why* please do I'm actually very intrigued
@shake n blake, something with sound waves. I can't explain exactly sorry!
@shake n blake, they're using a large array of many speakers all emiting noise at the same frequency. Since the frequency is the same the waves create nodes (areas of lower pressure) on the plate in geometric patterns. If the speakers emmited multiple frequencies you'd just see a jumbled mess. Just clever acoustics and a really light powder and good set up to show it
@TheWhiteWolf, So this is what sound looks like? (I failed high school physics, sorry, this just looks really cool and you sound like a smart person.)
@shake n blake, these are the patterns that certain sound waves make at certain hertz. I believe some of them are part of the solfeggio scale. It's basically sound waves being translated into shape i think. Super cool stuff
@TheWhiteWolf, not quite. This is a chladini plate. It generates perfect harmonics. See my other comment.
@KingofFunnypics, you haven't left another comment...
@TheWhiteWolf, so since the frequencies are all the same but the points on the platform that are the furthest away/least effected by a speaker are where the little grains accumulate since that is where they bounce the least?
@OneHellOfAButler, in 2 dimensions, with a constant tone, yes, sort of
@shake n blake, sort of. That's the basic idea of it, although distance to the sound source doesn't matter as much in this case since it's in an enclosed area
@TheWhiteWolf, yeah I think I get it, it's kind of like the vibrations coming from multiple angles are trapping the grains in position and not allowing them to move right? And different frequencies cause that position to be in different places. Very interesting. Thank you for explaining that to me. I appreciate it
@TheWhiteWolf, So like, if they ran some Metallica or Beethoven or something through that plate would it be cool patterns or just chaos?
@OneHellOfAButler, there'd be so many different, changing frequencies it's be just a vibrating jumble
@KingofFunnypics, even still the end effect is the same. Frequency should be frequency as long as you have the maths done right
@TheWhiteWolf, ok, thank you
@shake n blake, this is called a chladini plate, but the effect is actually not so hard to understand. Sound moves in waves, with peaks and troughs much like the ocean waves. Things collect in the troughs, because they are the areas with the least energy pushing the dust you see. This effect can be done in many ways, including water, and fire. Any lose particle or liquid will prefer to be in low energy areas because they are pushed their. If you want to learn more, watch the music video Cymatics, by Nigel Stanford. It's all stuff like this synced to music. They also have additional videos showing how it works.
You can actaully partially replicate these effects at home using a speaker that has a plastic cone, or perhaps Seran wrap over a speaker. Once set up, put a couple drops of water in. It will make patterns according to the song played. Dubstep in particular is quite exciting due to interference patterns, but any base heavy song looks cool. Just don't wreck the speaker.
@OneHellOfAButler, you may wish to see my comment. Or at least check out the Cymatics music video by Nigel Stanford. It's stuff like this, to his own music. Stunning to watch, and the behind the scenes shows how it's done.
@OneHellOfAButler, on sand, there would be no pattern you could see. In water, Dubstep will make clear interference patterns that look awsome.
@TheWhiteWolf, it took me a few minutes to type
@KingofFunnypics, woah ok, sounds awesome
@KingofFunnypics, Nps, good post. We were thinking along the same principles, that's what counts
@TheWhiteWolf, yeah, I just could never as a kid get my house speakers to do this. Which makes complete sense, but knowing about Chladini plates let me make my own experiment
@TheWhiteWolf, yeah. Same difference. I spent a solid month as a kid buying speakers and trying songs to make "pattern water"
@TheWhiteWolf, yeah we did this in physics! Experimented with certain frequencies and different shaped plates, or putting holes in them, it's all very interesting
@TheWhiteWolf, i think it's actually just 1 speaker. But yes.
@Weeee, the solfeggio scale contains all frequencies when set with a movable Do (if you use fixed Do I will, in fact, fight you)
@shake n blake, the study of sound waves making geometric patterns is Cymatics. There's videos on YouTube if wanted learn more and hear some of it.
@Comment Stalker, no, no fight. Only hugs and funnypics.
@TheWhiteWolf, this is actually a class experiment to display mode shapes based on excitation frequency. The plate is bolted in the middle to the top of a Shaker, which vibrates (shakes) at a given frequency. The mode shapes are similar to standing waves on a string. The sand collects at the nodes.
@AustinMother, again, same concepts being explored just different methods
*sigh* I miss dickbutt
@Pinkpuppetfred, here I am!
666 Hz: Satan's face
This isn't relevant but I just found out that I Shjt You Not is still active!
@Cowpoop, invalid chicken is active to. So is MACWE. They're always watching
@Good Ol Days, Kinda scared now...
@Cowpoop, uhhhh he literally posted something last week...
@RiffRaff, That's why I said *I* just found out.
So cool, it almost hertz to look at it
Who else was hoping for dickbutt
Must be FM.

"We control the vertical. We control the horizontal. We can focus on a single speck of light or inundate you with endless images. For the next sixty minutes, we will take you on a journey that stretches from the depths of the human imagination to... the Outer Limits! Please stand by..."
What is this sorcery?
I hope someday someone uses this as a way of creating an alien language for like a book or a game or something. Like turning frequencies into a language.
We turn our speakers up to eleven.
So now we can see sound
