Here’s a really neat way to see sound waves… With fire! I think if I ever make a fireplace, it’ll have something like this. Twinrawk writes – “The classic physics experiment involving sound, a tube of propane and fire. Created for Flash Forward 2006, but useful in any case where you are not allowed to have fire. I push through the tube 449 Hz then higher frequencies, then some jazz and then some rock. This is real life sound visualization.” [via] – Link.

  1. Woo!

    On the rock song… Is it playing off tape or something? Because it leaves rather nasty gaps in the visualization.

    Only thing… He’s burning propane in a closed garage. Hmm. Anyone see a problem with that?

  3. On the rock song… Is it playing off tape or something? Because it leaves rather nasty gaps in the visualization.

    The gap is caused because there is a standing wave there. Based on the length from the speaker to the large gap, I suspect there is a lot of musical information at about 175hz in the song.

    In open air a 175hz wavelength is about 6.5 feet. So we should see a standing wave at .5*wl or 3.25 feet.
