A Study on Directivity Design of Two Microphones Based on Meta-Strategy

Abstract (in Japanese) (See Japanese page) 
(in English) In general system of microphone arrays, the number of nulls is strictly limited under the number of microphones. We have succeeded to realize a suppression section having a constant low gain by using just two microphones. This method is based on some directional constraints. Removing those constraints, a directivity design problem can be formulated as an approximation problem to an ideal directivity characteristic. In this paper, such a problem is solved by meta-strategy method.
