I had been waiting for this video to show up on an actual video site (a few weeks ago when it first shot around the nets, it was a big browser-killer .mov). Michael Winslow imitates typewriters from history using only his mouth and a pair of microphones. Fascinating to see, actually, how much of a role his “playing” the microphones has in the sound.

This article on BBC News describes a “micro-ear” technology developed to listen to microscopic organisms. By using tiny (like two microns across) beads and lasers, the scientists can measure very small vibrations and amplify them.

In the “everything seems to do with things I’m learning in class” file: This video shows a proof of concept for a microphone that uses a laser and smoke for more accurate transduction of sound waves.

On Thursday in a class I’m auditing, we’ll be messing around with the basics of speakers and microphones. I’ll try to record some of that and put it up here for the sake of science.
