Audiologic results with the MSP/MPEAK and WSP/F0F1F2 processors and coding strategies for the nucleus cochlear implant.
Seven Nucleus, multichannel, cochlear-implant recipients underwent a 4-week trial with a Research Speech Processor (RSP). For five users of the Wearable Speech Processor (WSPIII), the RSP consisted of a Mini Speech Processor (MSP) with a MultiPeak (MPEAK) coding strategy, and for two MSP users, a WSPIII, utilizing an F0F1F2 coding strategy was used. Scores on an auditory-only, speech perception test battery were used to compare performance with each device. Patients were evaluated with their own processor before and after their RSP experience, to assess potential practice effects. In general, the patients with higher baseline scores appeared to be better able to take advantage of the additional information provided by the MSP/MPEAK combination.
