Acoustical signals from the acoustical surrounding (U) which impinge upon a reception unit 30 are evaluated and direction of arrival (DOA) of such signals is determined. From signals indicative of such direction of arrival (DOA) a histogram is formed in unit 32. The behavior of such histogram is classified under different aspects or criteria and dependent on classification results in a classifying unit 34 the hearing device and thereby especially its signal transfer characteristic from input acoustical signals to output mechanical signals is controlled or adjusted.
