The results indicate that the need for upgrading the processor and/or speech coding strategy should be considered individually, if the processor and coding strategy are functioning properly and a good level of speech perception has been achieved.
Our aim was to study the intra-individual differences of the body-worn CIS-PRO + and the behind-the-ear-worn TEMPO + cochlear implant systems used in the MED-EL Combi40/Combi40 + implants.
The hearing level, sentence, word and phoneme recognition of eight adult subjects were determined in an ABA study design. Additionally, a self-assessment questionnaire was used. Mean scores and 95% confidence intervals, and individual scores were analysed.
The subjects tended to score slightly better on word and phoneme recognition with CIS-PRO+ and CIS strategy than with TEMPO+ and CIS+, but there were no statistically significant differences. Subjectively the participants ranked speech perception and discussion in noise to be slightly easier with TEMPO+ and CIS+. Six of the eight subjects preferred TEMPO+ and CIS+ and two of eight preferred CIS-PRO+ with CIS or number-of-maxima.
结果表明，如果处理器和编码策略运行正常且已实现良好的言语感知水平，那么是否需要升级处理器和/或言语编码策略应单独考虑。
我们的目的是研究用于MED-EL Combi40/Combi40 +植入物的体佩式CIS-PRO +和耳背式TEMPO +人工耳蜗系统的个体内差异。
在ABA研究设计中确定了八名成年受试者的听力水平、句子、单词和音素识别能力。此外，还使用了一份自我评估问卷。分析了平均得分和95%置信区间以及个体得分。
与TEMPO+和CIS+相比，受试者使用CIS-PRO+和CIS策略在单词和音素识别上的得分往往略高，但无统计学显著差异。主观上，参与者认为使用TEMPO+和CIS+时言语感知和噪声中的讨论略容易一些。八名受试者中有六名更喜欢TEMPO+和CIS+，八名中有两名更喜欢带有CIS或最大数的CIS-PRO+。
