Listening device providing enhanced localization cues, its use and a method

A method of operating a listening device, the 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, the method comprising:

• providing at least two microphones signals, each being an electrical representation of an input sound;
• 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;
• providing a weighted sum of the at least two electrical microphone signals resulting in at least two directional microphone signals having maximum sensitivity in spatially different directions in said front and rear directions, and a combined microphone signal, each time-frequency unit of the combined signal being attributable to a particular direction;
• and
• modifying one or more selected time-frequency units of the combined microphone signal to indicate the directional cues of input sounds originating from at least one of said spatially different directions and providing an improved directional output signal.

A tangible non-transitory computer-readable medium storing a computer program comprising program instructions for causing a data processing system to perform a method of operating a listening device, the 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, wherein the method comprises:

• providing at least two microphones signals, each being an electrical representation of an input sound;
• 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;
• providing a weighted sum of the at least two electrical microphone signals resulting in at least two directional microphone signals having maximum sensitivity in spatially different directions in said front and rear directions, and a combined microphone signal, each time-frequency unit of the combined signal being attributable to a particular direction;
• and
• modifying one or more selected time-frequency units of the combined microphone signal to indicate the directional cues of input sounds originating from at least one of said spatially different directions and providing an improved directional output signal.
