A method for adjusting at least one hearing device, the method comprising: - providing the at least one hearing device with basic sound classes, each basic sound class comprising an actuator parametrization with parameters for at least one actuator of the hearing device; wherein the at least one hearing device: classifies an acquired sound signal with respect to the basic sound classes by generating an actual weighting in which each basic sound class is weighted with a basic weight value; generates an actual actuator parametrization for at least one actuator by interpolating the actuator parametrization of the basic sound classes at the actual weighting; processes the acquired sound signal with the at least one actuator parametrized with the actual actuator parametrization; outputs the processed sound signal to be perceived by a user of the hearing device; modifies the actual actuator parametrization based on adjustments of sound properties by the user; wherein the method further comprises: - collecting of adjustments of sound properties together with weightings at which the adjustments have been made; - analyzing the collected adjustments, whether same adjustments have been applied at same weightings; - generating at least one supplementary sound class, when the same adjustments have been applied at a weighting, wherein the actuator parametrization of the supplementary sound class is a modified actuator parametrization based on the adjustments at the weighting. - providing the at least one hearing device with basic sound classes, each basic sound class comprising an actuator parametrization with parameters for at least one actuator of the hearing device; wherein the at least one hearing device: classifies an acquired sound signal with respect to the basic sound classes by generating an actual weighting in which each basic sound class is weighted with a basic weight value; generates an actual actuator parametrization for at least one actuator by interpolating the actuator parametrization of the basic sound classes at the actual weighting; processes the acquired sound signal with the at least one actuator parametrized with the actual actuator parametrization; outputs the processed sound signal to be perceived by a user of the hearing device; modifies the actual actuator parametrization based on adjustments of sound properties by the user; wherein the method further comprises: - collecting of adjustments of sound properties together with weightings at which the adjustments have been made; - analyzing the collected adjustments, whether same adjustments have been applied at same weightings; - generating at least one supplementary sound class, when the same adjustments have been applied at a weighting, wherein the actuator parametrization of the supplementary sound class is a modified actuator parametrization based on the adjustments at the weighting. classifies an acquired sound signal with respect to the basic sound classes by generating an actual weighting in which each basic sound class is weighted with a basic weight value; generates an actual actuator parametrization for at least one actuator by interpolating the actuator parametrization of the basic sound classes at the actual weighting; processes the acquired sound signal with the at least one actuator parametrized with the actual actuator parametrization; outputs the processed sound signal to be perceived by a user of the hearing device; modifies the actual actuator parametrization based on adjustments of sound properties by the user; - collecting of adjustments of sound properties together with weightings at which the adjustments have been made; - analyzing the collected adjustments, whether same adjustments have been applied at same weightings; - generating at least one supplementary sound class, when the same adjustments have been applied at a weighting, wherein the actuator parametrization of the supplementary sound class is a modified actuator parametrization based on the adjustments at the weighting.
