Abstract

A novel concept for the determination of the weighting coefficients for weighted delay-and-sum microphone arrays is introduced in this contribution. The concept is based on a numerical optimization of the reception characteristic of the microphone array. The optimization procedure is shown to improve the reception characteristic in such a way that it closely approximates a target which can be defined according to the application.
