Comparative Study of Multi-channel Cochlear Implanted Patients Using SPrint Speech Processor With Using ESPrit Speech Processor / 听力学及言语疾病杂志

ABSTRACT

Objective To find out the difference in Multi-channel Cochlear mapping between SPrint speech processor and ESPrit speech processor (ESPrit 3G) for better guidance of the mapping.Methods Nine cases of total deafness patients (aged 2-54 years old) using SPrint changed to using ESPrit 3G after 6 to 24 months. The threshold (T-L) of electro-audiogram using different speech processor, comfortable level, sound field audiometry in various ESPrit 3G programs and questionnaire results were compared and analyzed statistically.Results Using various speech processor programs, four patients(The first group) felt satisfied with hearing effects. There was no difference comparing with SPrint. There was significantly different in T-L and C-L acquired from five patients(The second group) with two speech processors (P0.05). The results of sound field audiometry showed significant difference in the first group and the second group using programs from SPrint(P
