在文章中分别用线性窗及非线性的Ｂｌａｃｋｍａｎ窗门控的短音诱发１０只豚鼠的听性脑干反应（ＡＢＲ），以期观察比较它们对ＡＢＲ频率选择性的影响。结果显示线性窗门控短音因其边瓣宽而振幅大会引起兴奋的扩散，故频率选择性差。而Ｂｌａｃｋｍａｎ窗门控的短音既能满足诱发ＡＢＲ所需的快速上升时间，同时又可获得较窄的频谱从而使频率选择性得到保证。 In this paper, the auditory brainstem response (ABR) of 10 guinea pigs was induced by linear windows and nonlinear Blackman window-gated short beats, respectively, in order to observe their effects on the frequency selectivity of ABR. The results show that the linear window gating short tone because of its broad width and the amplitude of the excitement caused by the proliferation of large, so poor frequency selectivity. And the Blackman window-gated short tone can not only meet the fast rise time required to induce ABR, but also obtain a narrower spectrum and thus ensure the frequency selectivity.
