Video of Prototype Direction-Finding Microphone



 
 

Click on the still image above to see a video our current prototype direction-finding microphone in action.
A low resolution version is also available.

A digital readout of the source bearing (from LabView) is displayed on the computer screen. We see that the
needle follows the sound source as it is moved across the plane of the device.  We also see that the readout
stays steady if we repeatedly generate sounds at a single location.

The sounds in this video are generated by a small clicking toy in the shape  of an alligator. If your computer does
not support sound, the visual cue for the clicks is the opening of the animal's mouth.
