Systems and methods for maximizing loudness sensation in a cochlear implant patient

摘要

An exemplary system includes a processing facility configured to process an audio signal presented to a cochlear implant patient and a control facility configured to direct a cochlear implant to apply electrical stimulation representative of the audio signal to the cochlear implant patient by 1) directing the cochlear implant to concurrently apply a first biphasic stimulation pulse by way of a first electrode and a second biphasic stimulation pulse by way of a second electrode during a first time slot, and 2) directing the cochlear implant to concurrently apply a third biphasic stimulation pulse by way of the second electrode and a fourth biphasic stimulation pulse by way of a third electrode during a second time slot that immediately follows the first time slot. The third and fourth biphasic stimulation pulses are flipped in phase compared to the first and second biphasic stimulation pulses.

1. A method comprising:
directing, by a sound processor, a cochlear implant to concurrently apply a first biphasic stimulation pulse by way of a first electrode and a second biphasic stimulation pulse by way of a second electrode during a first time slot; and directing, by the sound processor, the cochlear implant to concurrently apply a third biphasic stimulation pulse by way of the second electrode and a fourth biphasic stimulation pulse by way of a third electrode during a second time slot that immediately follows the first time slot; wherein the third and fourth biphasic stimulation pulses are flipped in phase compared to the first and second biphasic stimulation pulses.
