SELECT: Towards more Selective Stimulation with Cochlear Implants

Duration: April 1st 2023 - March 31st 2026

Funding:

  • FFG Bridge

Co-operation partners:

  • MED-EL Corp., Innsbruck, Austria

Objective:

Current stimulation strategies for cochlear implants (CIs) use relatively high pulse rates to encode the channel-specific temporal envelope of speech sounds. This projects will combine psychophysical and auditory nerve response measures to build a model that allows to select perceptually relevant stimulation pulses and discard irrelevant pulses. The hypothesis will be tested that removing irrelevant pulses reduces the amount of within- and across-channel temporal interference and improves the access to timing cues (temporal pitch and interaural time differences). Further, it will be studied if this improves selective attention on a target speaker in presence of masker speakers that are separated in space and pitch from the target.
