Patent ID: 8787603

Claim:
A method for operating a hearing device ( 1 ) in a way that lets a hearing device user ( 10 ) acclimatize to said hearing device ( 1 ), said hearing device ( 1 ) comprising: a signal processing unit ( 9 ), a user control ( 4 ) by which at least one audio processing parameter (APP) of said signal processing unit ( 9 ) is adjustable by said hearing device user ( 10 ), and a non-volatile memory ( 7 ), said method comprising the steps of: a) writing a value indicative of a target power-on value (tPOV) for said audio processing parameter (APP) to said non-volatile memory ( 7 ), b) waiting until said hearing device user ( 10 ) switches on said hearing device ( 1 ), c) setting said audio processing parameter (APP) to a power-on value (POV), said power-on value (POV) being either stored in said non-volatile memory ( 7 ) or being calculated from values stored in said non-volatile memory ( 7 ), d) allowing said hearing device user ( 10 ) to continuously perform one or more adjustment actions by said user control ( 4 ) for adjusting said audio processing parameter (APP) to said hearing device user's preferences in varying listening situations, e) executing an acclimatization algorithm simultaneously with step d), after step d) and/or before step c), said acclimatization algorithm being designed to approximate said power-on value (POV) to said target power-on value (tPOV) after at least a week, said acclimatization algorithm determining a replacement power-on value (rPOV) for said power-on value (POV) taking into account which setting or settings for said audio processing parameter (APP) has or have been set by said hearing device user ( 10 ) and how long said setting or settings have been active, and f) repeating steps b) to e) until an acclimatization phase termination condition is fulfilled, wherein said acclimatization algorithm is a biased user preference learning algorithm, said biased user preference learning algorithm being derived from an unbiased user preference learning algorithm which is designed to determine a setting statistically preferred by said hearing device user ( 10 ) for said audio processing parameter (APP), said biased user preference learning algorithm being responsive to said adjustment actions in a way that adjustments in a first adjustment direction are taken into account stronger than adjustments in an opposing second adjustment direction, wherein said first adjustment direction is a direction towards said target power-on value (tPOV).
