The basic concept behind sound is the disruption or disturbance that transports energy from one place to another.
In other words, sound travels in invisible mechanical waves. For the most part it utilizes the particles that make up the air around you to transport the energy from the source (where the sound is created) to the destination (your ear).
Have you ever wondered what this sound might look like if you could actually see it?
Well, Sune Nielsen, a student at Aarhus University in Denmark, recently created what he calls the Pyro Board (in the video above).
The concept is very similar to the same one Heinrich Rubens applied when he created the Ruben’s Tube in 1905.
If you’ve never had the pleasure of viewing a Ruben’s Tube (pictured above) it is simply a long narrow tube with holes evenly drilled on side. The apparatus is then filled with a flammable gas and one end is hooked to a speaker that emits sound.
The frequency of the sound displays visually in waveform via the flames. Pretty neat huh?
Nielsen’s Pyro Board has some slight modifications (or upgrades), of course. Instead of using a singular pipe he has built a flat board with over 2000 holes drilled to create this stunning image.
If you want to find out some details about this experiment check out the full video below. It gets really cool around the 3:40 mark when they start to play some continuous music/sound and the flames really start dancing.
