Robert Alexander – Sonification

Robert Alexander works to give the sun a voice. As a sonification specialist at the University of Michigan, Alexander turns data from the sun into music.

And not only does it sound beautiful, but it can help further our understanding of the celestial body.

Alone, data collected from satellites around the sun sound like a gentle roar or low hum. Changes indicate the sun becoming more or less active over time, or as Alexander likes to call it, “heartbeats.”
