言语测听在助听器选配中的应用

背景:言语测听在助听器的选配中有决定性的作用,但中国临床应用较少。目的:通过言语测听了解耳内式助听器和耳背式助听器的使用者在言语分辨率上的差别。设计:配对对照实验。单位:解放军第四一四医院听力中心,江苏省听力康复中心。对象:选择就诊于解放军第四一四医院听力中心,江苏省听力康复中心耳聋患者62例。32例(耳)使用耳内式助听器耳聋患者中,平均听力损失(500,1000,2000,4000Hz)<85dB,年龄16～60岁。30例(耳)使用耳背式助听器耳聋患者中,平均听力损失(500,1000,2000,4000Hz)<85dB,年龄16-60岁。对实验均知情同意。方法:采用开放法和闭合法,分别对耳内式、耳背式助听器使用者,进行单耳聆听条件下的言语测试。言语信号类型选用单音节词和双音节词,每耳测听单音节词和双音节词各为20个。主要观察指标:耳内式、耳背式助听器对单、双音节词测听比较。结果:耳内式、耳背式助听器使用者的使用效果相比,在言语分辨率上无论开放式、闭合式对双音节词、单音节词的分辨率差异均无显著性意义(P>0.05);双音节词和单音节词的分辨率比较,开放式的状态下,差异有显著性意义(P<0.05);闭合式的状态下,差异无显著性意义(P>0.05)。结论:在助听器选配中言语测听的实际实施受诸多因素影响。

Application of speech audiometry in hearing aid selection

BACKGROUND: Speech audiometry is decisive in selecting hearing aid,but it is seldom used in clinic in China.OBJECTIVE: To understand the differences in the speech resolution with speech audiometry between in-the-ear (ITE) and behind-the-ear (BTE)hearing aids.DESIGN: Paired controlled study.SETTING: Auditory Center of the 414 Hospital of Chinese PLA, Auditory Rehabilitation Center of Jiangsu Province.PARTICIPANTS: A total of 62 patients with auditory disability were selected from the Auditory Center of the 414 Hospital of Chinese PLA and Auditory Rehabilitation Center of Jiangsu Province. Among 32 ITE hearing aid users, average hearing loss at 500, 1 000, 2 000 and 4 000 Hz, was less than 85 dB, and the patients were aged from 16 to 60 years. Among 30 BTE hearing aid users, average hearing loss at 500, 1 000, 2 000 and 4 000 Hz, was also less than 85 dB, and the patients were aged from 16 to 60 years. All patients were consent.METHODS: Open and close methods were adopted for speech audiometry among ITE and BTE hearing aids users. Monosyllabic and disyllabic words were chosen as the type of speech and 20 words were given to one ear, respectively.MAIN OUTCOME MEASURES: Comparison of speech resolution with monosyllabic and disyllabic words test between ITE and BTE hearing aid.RESULTS: In aspect of the effect of ITE and BTE hearing aids, there were no significant differences of both monosyllabic and disyllabic words no matter through open or close method (P ＞ 0.05). At the opening state, there were significant differences in resolution of monosyllabic and disyllabic words (P ＜ 0.05); while, there were no significant differences (P ＞ 0.05) at the closing state.CONCLUSION: Carrying out speech audiometry in the selection hearing aid is influenced by many factors.
