Switzerland-based photographer Fabian Oefner decided to connect visual world to an acoustic one in a way that would illustrate an actual sound wave in a photograph. He does it by putting some colorful pigments on the speaker which is covered with a thin foil. Then, when the sound goes through the speaker, it triggers some movements and the vibrating speaker makes the colors shout in the air. This is the moment when a colorful sound wave is formed. Thank you, laws of physics!
The artist’s job is to capture these moments so that we all could admire the dancing colors.
