摘要 

为了研究不同抑制准则值对刺激频率耳声发射抑制调谐曲线(stimulus frequency otoacoustic emission suppression tuning curves, SFOAE STCs)调谐特性的影响,该文测试了10名听力正常受试者在1、 2、 4kHz中心频率下,不同抑制准则值的SFOAE STCs, 并提取其特征参数: 调谐曲线品质因数(Q10)、 10dB带宽(BW10)、 顶点纵坐标偏移量等,运用统计学方差分析(analysis of variance, ANOVA)的方法进行抑制准则值对SFOAE STCs的特征参数的显著性水平分析。结果表明: 抑制准则值对SFOAE STCs调谐特性无显著影响,但是,随着抑制准则值的增大, SFOAE STCs更为尖锐,即其调谐特性更为敏锐。

Abstract

The effect of the suppression criterion on the tuning characteristic of stimulus frequency otoacoustic emission suppression tuning curves (SFOAE STCs) was studied for various suppression criteria of 1, 2, 4 kHz center frequencies with 10 normal hearing subjects. Characteristic parameters, such as quality factor (Q10)、10 dB bandwidth (BW10) and the level of tip, were extracted to evaluate the effect of the suppression criterion on the characteristic parameters using the analysis of variance (ANOVA). The significance of the characteristic parameters of the SFOAE STCs for the different suppression criteria with the 10 subjects shows that the suppression criteria have no significant effect on the SFOAE STCs tuning characteristic. However, the SFOAE STCs are more sharply tuned with larger suppression criteria.
