Abstract

In this chapter, we study an important family of third-order differential microphone arrays. In this family, which includes the hypercardioid and supercardioid, the directional patterns have exactly three distinct nulls. This feature simplifies the design of third-order DMAs. We will also see how this approach can be easily generalized to the Nth order.
