Abstract: The application relates to a hearing device, e.g. a hearing aid, comprising a sensor part adapted for being located at or in an ear or for fully or partially for being implanted in the head of a user. The application further relates to a hearing system. The object of the present application is to provide an improved hearing device. The problem is solved in that the sensor part comprises an electrical potential sensor for sensing an electrical potential, and the hearing device further comprises electronic circuitry coupled to the electrical potential sensor to provide an amplified output. The invention may e.g. be used in binaural hearing aid systems to control the processing, e.g. using EarEOG.

Abstract: A hearing device comprises a sound system for estimating the direction of arrival of sound emitted by one or more sound sources creating a sound field. The sound system comprises an array of N sound receiving transducers (microphones), each providing an electric input signal, a processing unit comprising a) a model unit comprising a parametric model configured to be able to describe the sound field at the array as a function of the direction of arrival in a region surrounding and adjacent to the array; b) a model optimizing unit configured to optimize said model with respect to its parameters based on said sound samples; c) a cost optimizing unit configured to minimize a cost function of the model with respect to said direction of arrivals; d) an estimating unit configured to estimate the direction of arrival based on said parametric model with the optimized parameters and the optimized cost function.
