Suggestion...turn headphones/speakers off....

Cool thou

That is pretty cool. Turning the speakers off is a good suggestion. My dog's ears perked up from across the room.

Wow...that's wild...

 

[matt.m]

That was indeed interesting.

Spelling's nahwt.

That was cool! I'm guessing the salt formed patterns based on the frequency of the soundwaves emanating through the platform?

 

[Carol]

The salt is reacting only vibration of the base platform, not to the sound itself. The base platform is reacting to the sound.

The platform has a specific resonant frequency...which basically means...the frequency at which it will vibrate when exposed to a pure sinusoidal wave.

Each frequency has harmonics.

As the pitch of the sine wave reaches harmonics of the base resonant frequency, the base vibrates in a different way. It is the evenness of the vibrations that creates the different pattern of salt.

And who says a B.Mus. in Music Production and Engineering is an impractical degree!!!

really neet, and haha thanks for the explanation
