How do you create the watersoundimages?
What´s needed for creating the images?
- shallow round bowl - black painted - speaker - audio-amp - frequency generator (software does as well - free software you get in the internet) - source of light - camera
Take the bowl an some silicon-glue and glue it on the membran of the speaker. Check that it´s really leveled. Fill the bowl with a little water. How much water depends on the size of the bowl - so you have to try. Plug the speaker to the amp and send a signal with the frequency generator through the amp to the speaker. check loudness and find a frequency (between 20-80 Hz is the easiest) where the water comes in resonance.
The camera and the source of light have to be directly above the bowl - so the light reflects the tops of the occuring waves.
That´s it. But it needs a lot of fine tuning to find the correct adjustments. If one factor is not right you won´t get a good image.
On this website you find a good description of how to build up the setting www.cymatics.org
Have fun trying! |
