To determine an auditory threshold of a test subject, according to the method, multiple tone sets, which predominantly contain a plurality of noises, having properties remaining uniform within a tone set, are presented in succession to a test subject by use of an output transducer. The test subject is asked to indicate a perceived number of noises from the presented tone set after each presentation of one of these tone sets. As a function of the perceived number of noises, a property of at least one part of the noises is changed in relation to the preceding tone set for the presentation of a following tone set and the following tone set is presented to the test subject. As a function of the respective perceived number of noises in the presented tone sets, at least one value of the auditory threshold of the test subject is estimated.

Method for determining the auditory threshold of a test subject, hearing aid system, method for setting hearing aid parameters and computer readable medium for performing the method

A fault recognition in a hearing aid of a user includes providing an actual image of a component of the hearing aid and comparing the actual image with reference images. An analysis unit carries out an image comparison, in which the actual image is compared to one or a plurality of reference images, which each show the component in a state, of which it is previously known whether the component is faulty or faultless. The analysis unit determines as a state of the component of the actual image that state which is assigned to the reference image which is most similar to the actual image. This recognizes whether the component is faulty or faultless. A system has an analysis unit that is configured to carry out the method.
