Hearing device or system comprising a noise control system

A method of operating a hearing system comprising a hearing device configured to be worn by a user, the method comprising

• providing at least one electric input signal representative of sound in the environment of the hearing device, wherein said at least one electric input signal comprises a) a target signal component assumed to be of current interest to the user, and b) a noise component;
• providing an output signal based on said at least one electric input signal, either comprising stimuli for being presented to the user, and/or for being transmitted to another device;
• providing an estimate of said target signal component and an estimate of said noise component in said at least one electric input signal, or in a signal originating therefrom,
• applying a statistical structure to said estimate of said noise component to thereby provide a modified noise component comprising said statistical structure;
• and
• determining a modified estimate of said target signal component in dependence of said modified noise component, and
• providing that said output signal comprises said modified estimate of said target signal component, or a further processed version thereof.

A hearing system comprising a hearing device configured to be worn by a user, the hearing device comprising

• at least two input transducers configured to provide respective at least two electric input signals representative of sound, wherein at least one of said at least two electric input signals comprises a) a target signal component assumed to be of current interest to the user, and wherein at least one of said at least two electric input signals comprises b) a noise component;
• an output unit configured to provide an output signal independence of said at least two electric input signals, either comprising stimuli for being presented to the user, and/or for being transmitted to another device;
• a noise control system configured to provide an estimate of said target signal component and an estimate of said noise component in said at least two electric input signals, or in a signal or signals originating therefrom;
• wherein the noise control system is configured
• to apply a statistical structure to said estimate of said noise component to thereby provide a modified noise component comprising said statistical structure;
• and
• to determine a modified estimate of said target signal component in dependence of said modified noise component, and
• wherein said output signal comprises said modified estimate of said target signal component, or a further processed version thereof.
