这项研究旨在调查真实耳朵测量声压级(SPL)的可靠性，并将这些值与SPL的两种耦合测量进行比较。一种商用的探针管麦克风系统被用来测量儿童和成人的真实耳SPL。两组的重测信度都随着频率的增加而降低，总体来说，儿童的重测信度稍差一些。在两组患者中，2c3耦合器与实际耳的差异均大于减小体积的耦合器，但两组间无显著差异。此外，耳道体积的测量并不能很好地预测耦合耳与真实耳的差异。
This study was designed to investigate the reliability of real-ear measurements of sound pressure level (SPL) and to compare these values with two coupler measures of SPL. A commercially available probe tube microphone system was used to measure real ear SPL in both children and adults. Test-retest reliability decreased as a function of frequency for both groups and, in general, was slightly poorer for the children. For both groups, coupler to real ear differences were larger for the 2 cm 3 coupler than for the reduced volume coupler; however, no significant differences were observed between groups. In addition, a measure of ear canal volume was not found to be a good predictor of coupler to real ear discrepancies.
