METHOD FOR OPERATING A HEARING SYSTEM, HEARING SYSTEM AND HEARING DEVICE
A method operates a hearing system having a hearing device and modifies an input signal for the purpose of sound output to a user and, applies multiple algorithms with a respective potency, as a result of which a respective algorithm is applied with a present potency in a present situation. The hearing system recurrently receives a report from the user indicating that the user is dissatisfied with the sound output in the present situation. The hearing system has a database, containing multiple weights for each algorithm, to rate a change of the potency. If a report is received, each of the algorithms is rated using the weights to ascertain an individual-case relevance for each of the algorithms, to assess the effect of a change of the potency. Multiple individual-case relevances are combined to form a relevance value for each algorithm, the relevance values are compared with one another.
