Abstract
A method and device are provided for automatic, recursive adjustment of at least one hearing device worn by a person. The device includes a stimulus generator unit, which emits at least one acoustic stimulus to the hearing device, a signal detection unit with at least one sensor, which detects the neuronal activity of the brain of the person due to the acoustic stimulus, a computation and control unit, which determines a measure of listening effort from the detected neuronal activity and determines changes to hearing device parameters from this. A hearing device control unit changes the hearing device parameters accordingly. The computation and control unit repeatedly prompts the stimulus generator unit to emit a hearing stimulus and the hearing device control unit to change a hearing device parameter, until the measure of listening effort drops below a predefinable first threshold value. This allows hearing devices to be adjusted objectively and automatically in a very robust and reliable manner.
