Classification: CPC H | IPC H

Claim 12:
13. A hearing device comprising
at least one earpiece configured to be worn at or in an ear of a user; and
a separate audio processing device;
the at least one earpiece comprising
an input transducer for converting sound in the environment of the hearing device to an acoustically received electric input signal representing said sound;
a wireless transmitter for transmitting said acoustically received electric input signal, or a part thereof, to said audio processing device;
a wireless receiver for receiving a first processed signal from said audio processing device, at least in a normal mode of operation of the hearing device; and
an output transducer for converting a final processed signal to stimuli perceived by, said user as sound,

the audio processing device comprising
a wireless receiver for receiving said acoustically received electric input signal, or a part thereof, from the earpiece, and to provide a received signal representative thereof;
a computing device for processing said received signal, or a signal originating therefrom, and to provide a first processed signal;
a transmitter for transmitting said first processed signal to said earpiece;
wherein said earpiece or said audio processing device comprises

a signal predictor for estimating future values of said received signal, or a processed version thereof, in dependence of a multitude of past values of said signal, thereby providing a predicted signal;
wherein said signal predictor is configured to fully or partially compensate for a processing delay incurred by one or more, such as all of
said transmission of the acoustically received electric input signal from the hearing device to the audio processing device,
said processing in the audio processing device, and
said transmission of the predicted signal or a processed version thereof to said earpiece and its reception therein;

wherein the final processed signal, at least in a normal mode of operation of the hearing device, is constituted by or comprises at least a part of said predicted signal.
