  • Electrophysiological method for assessing the effectiveness of a hearing aid
    Patent number: 10299696
    Abstract: A method of evaluating the effectiveness of an auditory prosthesis comprises transmitting a stimulus via an auditory prosthesis, thereby delivering an auditory stimulus to the auditory nervous system of a person fitted with said auditory prosthesis, picking up the neurophysiological signals transmitted by said auditory nervous system in response to the auditory stimulus by means of an electro- or magneto-encephalography system, and processing the received signals. The method also includes transmitting a stimulus made up of at least one pair of linguistic units selected from a phonetic confusion matrix, picking up a neurophysiological signal in response separately for each linguistic unit, and comparing the signals in order to evaluate the effectiveness of the prosthesis.
