Disclosed is a hearing device, an electronic device and a method for modelling a sound signal in a hearing device. The hearing device is configured to be worn by a user. The hearing device comprises a first input transducer for providing an input signal. The hearing device comprises a first processing unit configured for processing the input signal according to a first sound signal model. The hearing device comprises an acoustic output transducer coupled to an output of the first processing unit for conversion of an output signal from the first processing unit into an audio output signal. The method comprises recording a first object signal by a recording unit. The recording is initiated by the user of the hearing device. The method comprises determining, by a second processing unit, a first set of parameter values of a second sound signal model for the first object signal. The method comprises subsequently receiving, in the first processing unit of the hearing device, an input signal comprising a first signal part, corresponding at least partly to the first object signal, and a second signal part. The method comprises applying the determined first set of parameter values of the second sound signal model to the first sound signal model. The method comprises processing the input signal according to the first sound signal model.</p
