Abstract
Current sound processing strategies for cochlear implants are based on decomposing the audio signals into multiple frequency bands, each one associated with one electrode. However, these bands are relatively wide to accurately encode tonal components of audio signals. The CII and HiRes90K implants of Advanced Bionics LLC have the ability to share the stimulation current between two contacts (Current Steering). By stimulating two neighboring electrodes with different weights, the perception of different pitches is possible (Virtual Channels). Two new sound processing strategies based on the principle of current steering have been designed. The strategies have been evaluated with cochlear implant patients in a chronical trial and using an automatic speech recognizer.
