Abstract: In this paper we present a novel signal processing algorithm and array for sound source localization in an enclosed area. This method, which has some similarity to the human eye structure, consists of a novel hemispherical microphone array with microphones on the shell and one microphone in the sphere center. A signal processing scheme utilizes parallel creation of a special closeness functions for each microphone direction on the shell in the time domain. By choosing microphone directions corresponding to the highest closeness function values and implementing a linear weighted spatial averaging on those directions we estimate the sound source direction.
