Robust real-time constrained hearing aid arrays

The paper addresses the implementation of a real-time, robust, adaptive spatial filter used as a preprocessor for a monaural hearing aid. The goal of the ongoing study is the development of a processor that provides the user spatial selectivity and an attenuation of undesired interfering sources, while robustly controlling the response to a desired source. A four microphone, real-time, robust processor has been implemented and preliminary results are discussed in terms of improvement in SNR and an intelligibility measure.<
