Abstract: The hearing system (1) comprises at least one hearing device which comprises an operability control unit (3) and, operationally connectable thereto, a storage unit (4) in which operability data (5) are stored. The operability control unit (3) is structured and configured to either disable or not disable the hearing device (2) from functioning as a hearing device in dependence of the operability data (5), and the hearing system comprises no means for modifying the operability data (5), more particularly comprises no means for modifying the operability data stored in the storage unit (4). The method for operating a hearing system (1) comprises providing a hearing system (1) comprising at least one hearing device (2) comprising an operability control unit (3) and, operationally connected thereto a storage unit (4) in which operability data (5) are stored, wherein the hearing system comprises no means for modifying the operability data.

Abstract: A hearing device to be ordered in identified by a set (2) of data elements. Identifying data sets K[E] according to previous orders are stored (5) to such ordered data sets (K[E]) weighing values are assigned to (W[K]) which reflect the frequency of ordering hearing devices with respective data. The data set (2) of an intended order is compare with data sets of previous orders (K[E]) on the bases of a pre-established similarity criterion (#E). Similar data sets of previous orders are ranked according to the assigned weighing values (W[K]) and dispatched. The stored ordering data sets (K[E]) and the assigned weighing values (W[K]) are updated by an order for a hearing device which is placed.

Abstract: A hearing device and method for handling data in a hearing device that enables writing of the data into a storage location only under certain conditions. The conditions are: the data is being entered by a person who has previously entered data to the hearing device or the data has not been copied from a hearing device of a predetermined type or the hearing device has been enabled to unconditionally accept the data.
