Abstract
Presented herein are techniques for performing automated Electrocochleography (ECoG) testing using ambient sound signals received by a hearing prosthesis during normal operation (i.e., outside of a clinical setting). In particular, the hearing prosthesis analyzes ambient sound signals to identify portions of the sound signals that are conducive/suitable to the performance of an ECoG measurement (i.e., an ECoG measurement structure). When an ECoG measurement structure is identified, the hearing prosthesis itself performs an ECoG measurement using one or more implanted electrodes.
Claims21
A method, comprising:
- receiving sound signals at a cochlear implant comprising a plurality of electrodes implanted in a recipient's cochlea;
- analyzing the sound signals to identify Electrocochleography (ECoG) measurement structures within the sound signals;
- and
- following identification of an ECoG measurement structure, recording, with one or more of the plurality of electrodes implanted in a recipient's cochlea, a set of ECoG responses evoked by delivery of acoustic stimuli to the cochlea based on the ECoG measurement structure.
A hearing prosthesis, comprising:
- one or more sound input elements configured to receive ambient sound, wherein a plurality of portions of the ambient sound are delivered as acoustic stimuli to a cochlea of a recipient of the hearing prosthesis;
- one or more implanted electrodes positioned at least one of in or near the cochlea;
- an Electrocochleography (ECoG) monitoring system configured to utilize the one or implanted electrodes to record a plurality of sets of ECoG responses to the acoustic stimuli and to evaluate the residual hearing of the recipient based on the plurality of sets of ECoG responses.
