Abstract
(EN) Secondary path measurements and associated acoustic transducer-to-eardrum responses are obtained from test subjects. Both a least squares estimate and a reduced dimensionality estimate are determined that both estimate a relative transfer function between the secondary path measurements and the associated acoustic transducer-to-eardrum responses. An individual secondary path measurement for a user is performed based on a test signal transmitted via a hearing device into an ear canal of the user. An individual cutoff frequency for the individual secondary path measurement is determined. First and second acoustic transducer-to-eardrum responses below and above the cutoff frequency are determined using the individual secondary path measurement and the least squares estimate. A sound pressure level at an eardrum of the user can be predicted using the first and second receiver-to-eardrum responses.
(FR) Des mesures de trajet secondaire et des réponses transducteur acoustique-à-tympan associées sont obtenues à partir de sujets testés. On détermine à la fois une estimation des moindres carrés et une estimation de dimensionnalité réduite qui estiment à la fois une fonction de transfert relative entre les mesures de trajet secondaire et les réponses transducteur acoustique-à-tympan associées. Une mesure de trajet secondaire individuelle pour un utilisateur est réalisée sur la base d'un signal de test transmis par l'intermédiaire d'un dispositif auditif dans un conduit auditif de l'utilisateur. Une fréquence de coupure individuelle pour la mesure de trajet secondaire individuelle est déterminée. Des première et seconde réponses de transducteur acoustique-à-tympan au-dessous et au-dessus de la fréquence de coupure sont déterminées au moyen de la mesure de trajet secondaire individuelle et de l'estimation des moindres carrés. Un niveau de pression sonore au niveau d'un tympan de l'utilisateur peut être prédit au moyen des première et seconde réponses récepteur-à-tympan.
