Some sound wave drawings I did using illustrator, drawing over the photos from my experiments. The first set of patterns were from the speakers and the second set were from tapping the balloon surface of the can like a drum.
Some cool patterns form when you ‘cough’ into the can.
A video of the ‘sound visualisations’. I was quite close to the speaker when I filmed this so the sound quality is a bit off.

This time I decided to stick the mirror/CD on a speaker whilst music was playing out, the vibrations were much stronger and created different patterns and larger shapes.
Some screen captures from the video.

I attempted a different version of the experiment in the post below from a simple tutorial I found online. Using a can, cutting the top and bottom off so you can speak into it from one side whilst the balloon at the top vibrates. A mirror is attached on the section with the balloon, I used a CD as I did not have a mirror and a laser is reflected off the CD on to a wall. When I ‘spoke’ or ‘sung’ into the can the shapes formed above. I found that lower pitches made bigger circles or ‘loops’. It was quite difficult to achieve the shapes on the wall as I used a CD the reflections were blurry or maybe I should try using a different container to get more vibrations going, or replace the balloon with a similar material.
