The objective of this study is to review the scientific literature to determine if a set of stimulus parameters can be described to elicit distortion product otoacoustic emissions (DPOAEs) of higher absolute level and/or greater reliability in healthy adult humans and higher sensitivity and specificity in adults with cochlear lesions.
Systematic review.
Searches of four electronic databases yielded 47 studies that had used different parameters to elicit DPOAEs from within or between-groups of adult humans.
The wide range of stimulus parameters used in the reviewed studies saw a wide range of reported values for DPOAE level, reliability, and sensitivity and specificity to cochlear lesions.
The most commonly used stimulus parameters for eliciting DPOAEs from adult humans have included frequency ratios for the two primary tones (f/f) of between 1.04 and 1.4 and levels (L/L) of 65/55 dB SPL. The most commonly used parameters for eliciting DPOAEs of higher level in healthy adults appear to be linked to f/f values between 1.20 and 1.22 and L/L levels of 75/75 dB SPL. The stimulus parameters for eliciting DPOAEs of greater reliability in healthy adults and higher sensitivity and specificity in adults with cochlear lesions have yet to be clearly determined.
本研究的目的是回顾科学文献，以确定是否可以描述一组刺激参数，从而在健康成年人中引出绝对水平更高和/或可靠性更高的畸变产物耳声发射（DPOAE），并在患有耳蜗病变的成年人中引出更高的敏感性和特异性。
系统评价。
对四个电子数据库的检索产生了47项研究，这些研究使用了不同参数从成年人群组内部或之间引出DPOAE。
在所回顾的研究中使用的刺激参数范围广泛，DPOAE水平、可靠性以及对耳蜗病变的敏感性和特异性的报告值范围也很广泛。
从成年人中引出DPOAE最常用的刺激参数包括两个主要音调的频率比（f2/f1）在1.04至1.4之间，以及强度（L1/L2）为65/55 dB SPL。在健康成年人中引出更高水平DPOAE最常用的参数似乎与f2/f1值在1.20至1.22之间以及L1/L2水平为75/75 dB SPL有关。在健康成年人中引出可靠性更高的DPOAE以及在患有耳蜗病变的成年人中引出更高敏感性和特异性的刺激参数尚未明确确定。
