We evaluated the auditory system of 41 children by means of evoked otoacoustic emission. The children were selected from a school population and range in age from 3 to 16 years. No hearing problems were detected prior to this study. The stimulus was a nonlinear click with a frequency of 21/s. All the children but one had echo sizes over 9.72 dB SPL. The mean echo size was 13.23 dB SPL with a reproducibility of 74.81%. Average echo sizes for each frequency are presented. There were no significant differences in the series with respect to the adult comparative pattern used except for the child with an unknown perceptive disorder. We conclude that the test is reliable and highly sensitive, and that it detects small conductive and sensory hearing losses. It is fast, easy, painless and does not require sedation, making it particularly interesting for hearing assessments in childhood.
我们通过诱发耳声发射评估了41名儿童的听觉系统。这些儿童选自学校学生群体，年龄在3至16岁之间。在本研究之前未检测到听力问题。刺激声为频率为21次/秒的非线性短声。除一名儿童外，所有儿童的回声大小均超过9.72 dB SPL。平均回声大小为13.23 dB SPL，再现率为74.81%。给出了每个频率的平均回声大小。除了一名患有不明感知障碍的儿童外，该系列与所使用的成人对照模式相比没有显著差异。我们得出结论，该测试可靠且高度敏感，能够检测出轻微的传导性和感音性听力损失。它快速、简便、无痛且无需镇静，这使得它在儿童听力评估中特别有意义。
