项目摘要

Otoacoustic emissions are useful to estimate the status of individual cochlear function. Especially in transiently evoked otoacoustic emission (TEOAE), the averaged waveform and the power spectrum provide the different kinds of information concerning the cochlear response to the stimulus in frequency and time domain, and also provide the inter-individual difference in response. The possibility of the TEOAE measurement to assess the responsibility of the cochlear to speech sound was investigated in the present study, since some objective measurement for the function of cochlear, the organ for communication, to speech sound was thought to be necessary.We investigated TEOAEs evoked by complex stimuli as a model of vowel and monosyllable Japanese word component. Five kinds of tone burst stimuli were generated using tone burst generation function of ILO88 as the model of vowel. The published mean frequencies of the vowel formants evaluated in Japanese young women were introduced into tone b … More urst generation. Furthermore, also the complex tone bursts were created in the same way using click and the tone burst models of vowel as the model of the monosyllable Japanese word component. TEOAEs were recorded with ILO88 Otodynamic Analyzer and the wave form and the power spectrum were investigated in terms of inter-stimulus and inter-individual difference respectively.In the results, the waveforms of TEOAE evoked by the vowel models indicated inter-stimulus and inter-individual differences. The power spectrum of TEOAE corresponded to the components of each stimulus. The test-retest stability of TEOAE was confirmed within one-year period. The waveform of TEOAE evoked by the model of the Japanese monosyllable word components also indicated inter-stimulus and inter-individual difference and the early and the late component of the waveform were mainly affected by the click and the vowel component respectively.From these results, we concluded that the long-term stability, the inter-stimulus and the inter-individual difference of the TEOAE waveform were confirmed and the characteristics of complex stimuli were reflected in the wave form and the power spectrum of TEOAE. The function of monosyllable perception, however, could not be estimated in the present method objectively in hearing normal subjects. Less

耳声发射可用于评估个体耳蜗功能状态。特别是在瞬态诱发耳声发射（TEOAE）中，平均波形和功率谱提供了耳蜗对刺激的反应在频域和时域上的不同信息，也提供了反应的个体差异。为了探讨TEOAE测量评价耳蜗对言语声反应的可能性，本研究以日语元音和单音节词成分为模型，研究了复杂刺激诱发的TEOAE。以元音为模型，利用TMS88的短纯音产生函数，产生了五种短纯音刺激。已发表的平均频率的元音共振峰评价在日本年轻妇女被引入到语气B ...更多信息第一代。此外，还以同样的方式使用点击和元音的短纯音模型作为单音节日语单词成分的模型来创建复杂的短纯音。采用TEOAE测试仪记录TEOAE波形，分析其波形和功率谱的刺激间差异和个体间差异，结果表明，不同元音模型诱发的TEOAE波形存在刺激间差异和个体间差异。TEOAE的功率谱对应于每个刺激的分量。TEOAE在一年内的重测稳定性得到证实。由日语单音节词成分模型诱发的TEOAE波形也表现出刺激间和个体间的差异，其波形的早、晚成分分别主要受短声和元音成分的影响。证实了TEOAE波形的刺激间差异和个体间差异，TEOAE波形和功率谱反映了复杂刺激的特征。然而，目前的方法不能客观地评价听力正常者的单音节知觉功能。少
