Title
(EN) HEARING INSTRUMENT WITH T-COIL
(FR) APPAREIL AUDITIF COMPRENANT UNE BOBINE EN T
Abstract
(EN)
There is provided a hearing instrument comprising a T-coil antenna (14) for picking up an inductively transmitted base-band audio signal, an audio signal processing unit (16) for processing the picked-up T-coil audio signal, and an output transducer (18) for stimulation of the user's hearing according to the processed audio signals, and a functional unit (22) being adapted to operate in a duty cycling mode and to communicate to the audio signal processing unit the interference points in time at which the functional unit is switched from its inactive state to its active state and/or from its active state to its inactive state, wherein the audio signal processing unit is adapted to apply a click removal treatment to the T-coil audio signal during said interference points in time at time at which the functional unit is switched to and/or from its active state.
(FR)
L'invention concerne un appareil auditif comprenant une antenne à bobine en T (14) pour capter un signal audio en bande de base transmis par induction, une unité de traitement de signal audio (16) pour traiter le signal audio de bobine en T capté, et un transducteur de sortie (18) pour stimuler l'ouïe de l'utilisateur en fonction des signaux audio traités, et une unité fonctionnelle (22) conçue pour fonctionner dans un mode de cycle de service et pour communiquer à l'unité de traitement de signal audio les points d'interférence dans le temps auxquels l'unité fonctionnelle est commutée de son état inactif à son état actif et/ou de son état actif à son état inactif. L'unité de traitement de signal audio est conçue pour appliquer un traitement de suppression de clic au signal audio de bobine en T pendant lesdits points d'interférence dans le temps au moment où l'unité fonctionnelle est commutée vers et/ou de son état actif.
