Abstract
An apparatus and method for creating a MEMS directional sensor system capable of determining direction from at least two microphones to a sound source over a wide range of frequencies is disclosed. By utilizing a stiff beam stand-off architecture that relies on a unique manufacturing technique in a MEMS device, such as described herein, a very small set of microphones, on the order of a few micrometers, can be designed with unsurpassed ability to detect a sound source location.
