A novel near field filter-and-sum beamformer using non uniform frequency sub-bands is presented. The concept is based on numerical optimization of the reception characteristic of the microphone array. In order to improve the reception characteristic over frequency and space, a non uniform filterbank is utilized to subdivide the frequency range. Individual(More)
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(More)
