Abstract:
1. A listening device, comprising: an ear-part adapted for being worn in or at an ear of a user, a front and rear direction being defined relative to a person wearing the ear-part in an operational position; a microphone system comprising at least two microphones each converting an input sound to an electrical microphone signal; a TF-conversion unit for providing a time-frequency representation of the at least two microphone signals, each signal representation comprising corresponding complex or real values of the signal in question in a particular time-frequency unit; a DIR-unit comprising a directionality system for providing a weighted sum of the at least two electrical microphone signals thereby providing at least two directional microphone signals having maximum sensitivity in spatially different directions and a combined microphone signal, each time-frequency unit of the combined signal being attributable to a particular direction; and a frequency shaping-unit for modifying one or more selected time-frequency units of the combined microphone signal to indicate directional cues of input sounds originating from at least one of said spatially different directions and providing an improved directional output signal.
