双侧人工耳蜗植入术后言语识别效果的评估
Evaluation of speech perception in patients with bilateral cochlear implant
摘要
Abstract
Objective To evaluate the recognition effectiveness of bilateral cochlear implant recipients’Mandarin phras-es, monosyllabic words and disyllabic words, and explore the mechanism of bilateral cochlear implantation (BCI) binaural hear-ing and its influences to the speech recognition rate. Method 6 BCI patients were selected surveyed with a questionnaire about their basic information and assessed their subjective hearing status. First, their auditory threshold were tested under BCI and RCI/LCI mode, then their recognition rate of seven-syllables phrases, disyllabic words, tones, vowels and consonants were tested under the aforementioned two modes. The testing ambient includes both quiet and noisy background. The speech signal strength was set to 65dB SPL, with a fixed signal-to-noise ratio of+10 dB SPL. The effectiveness of recognition from BCI and RCI/LCI were compared and correlation analysis was conducted. Results Except for the vowel perception test , all of the per-ception rates of BCI are better than RCI/LCI. Conclusion For patients that fit the BCI indicator criteria, BCI can improve the recognition rate of phrases, disyllabic words, consonants, vowels and tones under quiet and noisy ambient in various degree, and lower their sound field auditory threshold.关键词
