I know what makes the salt act like that:
1. Soundwaves, the are naturrally in PATTERN
2. move with 340 meters per second
3. The salt begin to move with the soundwaves.
4. When the sound is so loud that the salt start to shake on the speaker, it lifts and is picked up by the soundwaves.
5. A pattern that interfer with a large amount of small materials , as salt, creates a pattern of the small materials.

Cool, but i dont see any logic in the forms of the pattern... I mean I get what Tobbe was saying, but why THESE patterns are formed on certain frequencies, some of them look very complicated. Can anyone explain or link to a site that explains?

RadioActive Chief (guest) - May 22, 2006, 19:53
As the pitch increases, the pattern complicates due to the expression of higher order harmonics. Like a half-wave length antenna wire ALSO is resonant at 1/4 wave, 1/8 wave, 1/16 wave, etc. Since this is a planar surface instead of a linear wire, the possibilities for complexity are greater due to the 2-dimensionality of the flat plane.

salt?? pah! you should have seen the effect that that noise had on my dog. :p
gobblox (guest) - May 23, 2006, 01:04
it has to do with the certain frequencies that the plate of metal will resonate them, you will notice as the note gets higher, the 'regions' that form in the salt get smaller and more numerous as the note gets higher.
im no expert, so dont go qouteing me, but i remember doing something similar in highschool physics using an ultra sonic generator and plates of various shapes.
Aminos (guest) - May 23, 2006, 02:58
Unbelivable !! O_O
Sim (guest) - May 23, 2006, 06:42
The sound waves in the plate interfere with each other and the salt accumulates at the 'knots', the boundaries where there is a destructive interference. The shapes look like something out of my quantum mechanics class, a waveform or something. Really nice! :D
pre (guest) - May 23, 2006, 06:44
its all the same shape, the only thing changing is the wave is geting faster (or shorter) as the pitch goes higher
Dantalion - May 23, 2006, 07:25
Yeah the patterns reminded me ideed of the hydrogen-atom patterns according to quantummechanics... only these are 2D.

If you look closely, the beginpattern is in every new pattern(if you look with a bit of imagination) Therefor sound always has the same pattern, only at higher tones the pattern gets more complex

They are formed by standing waves, and the addition and cancelation of waves. We did this in a physics lesson and i have a test on it in a week, i really should know more about it...
bob (guest) - June 5, 2006, 11:13
how would you recreate this? metal plate + salt + something that vibrates the plate with sound waves? if not too expensive i would love for my neice to do this as a school project.

not goood listening too that with a headache i suppose.
Samurai (guest) - August 12, 2006, 00:09
It really has nothing to do with sound. Sound is just a byproduct. What they're doing is just shaking the platform at increasing frequencies. All objects have certain frequencies that they resonate at naturally. These frequencies are special because the waves of vibration traveling through the surface create a standing wave, much like when you shake a jump-rope with one end tied; when the peaks and troughs, and more importantly the nodes, stay in the same spot. The sand, salt, rice whatever, then moves away from the parts of the surface that moves from peak to trough and gathers in the spots where the nodes are (the areas of the syrface that move the least.)

HR Soundproductions (guest) - September 6, 2006, 10:53
It;s all about vibration ( like samurai explained ,but don't rule out the sound. Sound( tone hight)will increase or decrease the resonance in the board.

Acoustic Engineer (guest) - November 10, 2006, 19:43
Mr. Tobbe - I am afraid your answer would not suffice in a high school class, much less a class with sufficient theory to predict these patterns.
Yes, sound is a wave.
Yes, you see patterns.
Now, please try again.

I still have tinnitus even after a few minutes of reading. [b]Samurai,[/b] I thought sound was vibration, and it was that vibration which travels through the plate and creates the partials to move?

That's understandable that cash can make us free. But how to act if someone doesn't have money? The only one way is to receive the credit loans and small business loan.
