Method and arrangement for fitting a hearing system

The method for adjusting a hearing system (2) to the preferences of a user (3) of the hearing system comprises a) playing an audio sequence to said user (3); wherein the audio sequence comprises a first sound object representative of a first real-life sound source and a second sound object representative of a second real-life sound source; b) receiving an input (R) in response to step a); c) adjusting at least one audio processing parameter (P) of said hearing system (2) in dependence of said input (R). Preferably, the method further comprises d) providing the user (3) synchronously with step a) with a visualization of a scene to which said audio sequence belongs; and providing a user input (U) which is indicative of a sound source or of a sound object or of an instant in or a portion of the audio sequence; and automatically selecting an audio processing parameter (P) of the hearing system (2) in dependence of the user input (U) and offering the selected audio processing parameter (P) for adjusting.
