ABSTRACT:
A hearing aid wearer's own voice frequently leads to artifacts and response errors in various hearing aid algorithms. It is provided that the user's own voice to be detected by a special analysis device, and the hearing aid algorithms can be controlled as a function of detection. This can be achieved by providing a microphone in the auditory channel whose signal level is compared with that of an external microphone. This allows some form of control, e.g., the automatic gain control of a hearing aid to be “frozen”, in the presence of the hearing aid wearer's own voice.
