Method and system for adjusting a hearing device to personal preferences and needs of a user

A system for adjusting a hearing device to personal preferences and needs of a user of the hearing device, comprising:

• the hearing device with an input transducer for receiving an input sound signal, an audio signal processing unit adapted to process the input sound signal dependent on a current setting for one or more signal processing parameters, and an output transducer for providing the processed sound signal to the user;
• a user control element operable by the user;
• a memory unit adapted to store an initial settings for the one or more signal processing parameters and a target setting for the one or more signal processing parameters, the initial setting associated with a start time of an acclimatization time period and the target setting associated with an end time of the acclimatization time period;
• a controller adapted and to:
• perform an acclimatization process in which the current setting is gradually adjusted from the initial setting to the target setting, the current setting associated with a current usage time within the acclimatization time period;
• detect user input, provided by the user by way of the user control element during the acclimatization process, that adjusts the current usage time to an adjusted usage time within the acclimatization time period;
• and
• update, based on the user input, the acclimatization process to gradually adjust the current setting from the adjusted setting to the target setting.
