WebAbstract: Adaptive beamforming techniques can be applied to the problem of reducing interference in monaural hearing aids from sound sources that are spatially separated … WebAbstract. This chapter presents robust adaptive beamforming techniques designed specifically for microphone array applications. The basics of adaptive beamformers are first reviewed with the Griffiths-Jim beamformer (GJBF). Its robustness problems caused by steering vector errors are then discussed with some conventionally proposed robust ...
