Abstract: A method for transmitting information relating to a hearing device, in particular a hearing aid, to an external device. The hearing device is thereby placed in an immediate environment of the external device and the hearing device broadcasts a generally receivable, unencrypted first information item containing metadata about the hearing device and/or access data. The unencrypted first information item is received by the external device. The external device changes its operating mode directly or indirectly as a result of the first information item and continues to be operated with the modified operating mode.

Abstract: A method fits a digital hearing aid having an input transducer, a signal processing device and an output transducer. The signal processing device is configured to form an evaluation unit, a comparator unit, and a pre-amplification unit. An acoustic test signal is generated by an external testing device while the hearing aid is worn by a hearing-aid wearer. A digital test input signal is generated by the input transducer on the basis of the acoustic test signal. A sound pressure-dependent test quantity is determined on the basis of the digital test input signal by the evaluation unit. A deviation between the sound pressure-dependent test quantity and a reference quantity stored in the signal processing device is determined by the comparator unit. A pre-amplification by the pre-amplification unit is adjusted on the basis of the determined deviation.
