Abstract

The present study evaluates the short-term effect of cochlear implantation on the fundamental frequency (FO) of 13 deaf patients. All patients were provided with the Combi 40+ cochlear implant. Voice recording was made pre- and 3 months post-implantation. The FO was analysed using X-Tools software. The results showed that 38 per cent of our subjects had a statistically significant decrease of their mean F0 (p=0.001) at 3 months following implantation. It was also observed that the patients tended to have a lower F0 postoperatively approaching the normal range of F0. A large variability in F0 was noticed among the deaf subjects but no correlation with the duration of deafness was seen. There was also no correlation between speech recognition and speech production.

耳蜗植入术后听觉反馈对基频的短期影响。
本文对13例耳聋患者进行了人工耳蜗植入术对其基频(FO)的短期影响。所有患者均行Combi 40+人工耳蜗植入。分别在植入前和植入后3个月进行录音。使用X-Tools软件对FO进行分析。结果显示,38%的受试者在植入后3个月的平均F0下降有统计学意义(p=0.001)。我们还观察到,患者术后F0趋于较低,接近F0的正常范围。在失聪受试者中,F0有很大的差异,但与失聪持续时间没有相关性。语音识别和语音生成之间也没有相关性。
