Directivity
and Matched Microphones

ABOUT
THE PRESENTATION:
This
talk discusses the basics of microphone directivity, particularly
using two closely spaced microphones. We will show why the
microphones in these small directional systems must be very
closely matched in sensitivity across the frequency band for good
directional performance, and how we pull this off even though the
matching tolerances are approaching the limits of our ability to
measure the microphones.
