Gadget Freak Case #240: MEMS Mics Up Telescope

May 09, 2013

One of the problems with wildlife video photography is that you can get close to the animal with a telescopic video lens, but what about the sound? It's still far, far away.

Jerald Cogswell came up with a solution. He created a sonic telescope to grab sound and bring it as close to the user as the visual image. Biologists can also use this MEMS microphone to listen to insects and burrowing animals. The microphone can take the sound and match it to the proximity of the image.

Jerald Cogswell mounted a precision MEMS microphone in a satellite dish's focal point so it can feed its signal to an amplifier that enables simultaneous recording and monitoring via headphones.
