本研究的目的是比较三种最常用的初级关系范式(即剪刀法、男童镇最佳关系范式和等水平关系范式)在正常听力成年人的失真产物耳声发射(DPOAE)产生方面的差异。从每个范式中的DPOAE中提取生成器和反射分量。生成器和反射组件级别以及输入/输出(I/O)函数跨范例和基音级别进行了比较。结果显示，不同范例之间的I/O函数增长行为在频率和级别上有所不同。最优范式显示，受试者在初级水平上的产生器和反射成分水平以及I/O斜率发生了系统性的变化。此外，最优范式中的水平和斜率在不同水平上更加明显，不同频率之间的差异较小，从而导致DPOAE精细结构在不同水平上发生系统变化。发现I/O函数对所选范例更敏感；尤其是反射组件的I/O函数。反射分量的I/O函数在频率上表现出很大的变异性，这是由于它们的微观结构根据范例的不同而发生不同的频率偏移。这项研究的结果表明，最优的范式是研究耳蜗放大/压缩的合适的初级关系。这项研究的结果表明，需要注意比较不同研究的结果，这些研究产生了具有不同层次关系范式的DPOAE。
The goal of this study is to compare three of the most commonly used primary-level relation paradigms (i.e., Scissors, Boys Town ‘Optimal’, and Equal-Level) in generation of distortion product otoacoustic emissions (DPOAEs) in normal hearing adults. The generator and reflection components were extracted from DPOAEs in each paradigm. The generator and reflection component levels and input/output (I/O) functions were compared across paradigms and primary-tone levels. The results showed a different I/O function growth behavior across frequency and levels among paradigms. The Optimal paradigm showed a systematic change in the generator and reflection component levels and I/O slopes across primary levels among subjects. Moreover, the levels and slopes in the Optimal paradigm were more distinct across levels with less variations across frequency leading to a systematic change in the DPOAE fine structure across levels. The I/O functions were found to be more sensitive to the selected paradigm; especially the I/O function for the reflection component. The I/O functions of the reflection components showed large variability across frequencies due to different frequency shifts in their microstructure depending on the paradigm. The findings of this study suggested the Optimal paradigm as the proper primary-level relation to study cochlear amplification/compression. The findings of this study shows that care needs to be taken in comparing the findings of different studies that generated DPOAEs with a different level-relation paradigm.
