Neon Lamp Traces Sound Wave’s Picture That’s a sound wave you see in the picture above. Here demonstrating how an acoustic lens focuses sound from a horn, the wave was made visible with the device at left – an aluminum rod with a microphone and a neon lamp at the end. A small motor swings the rod in a wide arc, scanning the area. The microphone picks up the sound and turns it into electric current to feed the lamp. Wherever the sound is strongest, the light is brightest, and the wave is traced out. A complete sound photo, such as this from Bell Labs, takes 10 minutes exposure. ~ Bell Labs
Beach Bells: You Still Believe In Me
from Alexander Chen
This is a visualization of Beach Boys vocals inspired by the physics of church bells. Using a mathematical relationship between a the circumference of a circular surface and pitch, I wrote code that draws a circle for each note of the song.
Made with Processing, Midibus library, and Ableton Live. Learn more about the rich physics behinds real bells here: goo.gl/P6Zpr
