Traveling wave based group delays for cochlear implant speech processing
نویسندگان
چکیده
Cochlear implant speech processors seek to generate a neural response that mimics normal hearing. However, the cochlear phase response is generally discarded, together with other fine scale temporal aspects of sound. We sought to incorporate and compare a variety of cochlear traveling wave delays (i.e. group delays) in a clinical speech processing strategy. Traveling wave delays resulted in a significant improvement in the perception of speech in noise, a longstanding difficulty for cochlear implant patients.

First and second group were selected, ordinarily, from ch...
متن کاملUsing a Personal Computer to Perform Real-Time Signal Processing in Cochlear Implant Research
Cochlear implants are electronic devices that have enabled individuals with severe to profound hearing losses to regain some hearing. There is, however, substantial variability in speech perception performance among users of cochlear implants. One factor that may contribute to the individual differences is the way in which the device converts acoustic sound waves into electrical stimulation: th...
متن کاملRelationship between Electrically Evoked Compound Action Potential Thresholds and Auditory, Language, and Speech Progress after Cochlear Implant Surgery
Introduction: Electrically evoked compound action potential (ECAP) is an objective auditory response that can be used in the programing of cochlear implants. The aims of this study were to monitor ECAP thresholds and auditory, language and speech progress for 6 months after cochlear implant surgery and to evaluate any relationship between them. Materials and Methods: Ten children with a m...
متن کاملRemote fitting of cochlear implant system.
Objectives The fitting procedure of the cochlear implant system introduced in the International Center of Hearing and Speech requires repeated fitting sessions that take place from 3 to 12 times per year, depending on the experience of cochlear implant recipient. Very often patients' visits involve traveling considerable distances. Patients, especially small children, are tired when arriving to...
