Method for operating a hearing system, hearing system and hearing device

A method for operating a hearing system having a hearing device and a database, which comprises the steps of:

• configuring the hearing device to modify an input signal for a purpose of sound output to a user and, to that end, to apply multiple algorithms with a respective potency, as a result of which a respective algorithm of the algorithms is applied with a present potency in a present situation;
• configuring the hearing system to recurrently receive a report from the user indicating that the user is dissatisfied with the sound output in the present situation;
• configuring the database to contain a plurality of weights for each of the algorithms, in order to affect a rate of change of the respective potency, wherein, if the report is received, each of the algorithms is rated by using the weights to ascertain an individual-case relevance for each of the algorithms, in order to assess an effect of a change of the respective potency in the present situation;
• and
• combining multiple individual-case relevances to form a relevance value for each of the algorithms, relevance values are compared with one another, this is taken as a basis for selecting a most relevant algorithm, and then an adapted potency is used for the most relevant algorithm by adapting the present potency of the algorithm for a recommended potency determined on a basis of the weights.
