20220280796 | COCHLEAR IMPLANT SYSTEM WITH IMPROVED INPUT SIGNAL-TO-NOISE RATIO - A cochlear implant system can comprise an input source configured to receive a stimulus and generate an input signal representative of the stimulus, a cochlear electrode, a stimulator in communication with the cochlear electrode configured to provide electrical stimulation to cochlear tissue via the cochlear electrode, and a signal processor programmed with a first pulse rate. The signal processor can be configured to receive the input signal from the input source and filter the input signal based on the first pulse rate such that one or more frequencies associated with the first pulse rate in the received input signal are attenuated. The signal processor can further be configured to output a stimulation signal to the stimulator based on the filtered input signal with the stimulation signal causing the stimulator to provide electrical stimulation to the cochlear tissue at the first pulse rate. | 2022-09-08 |
