Vibrations and how they get to your ears.
Noise for airports is a blog about culture, sound, music, and technology.
You can filter the posts to see just things I wrote or made.

I always feel a little silly reblogging things from Boing Boing (like you haven’t seen them already), but I grabbed a better image of this 1892 cylinder copying device, so here you go.
The image is from this patent for a “Method of and Means for Duplicating or Transferring Phonograph Records.” On Boing Boing, it’s in a post about (guess what) copyright and DRM.
