The Oldenburg children's rhyme test (OlKi) was designed and optimized for speech intelligibility measurements for primary school pupils in silence [8, 3]. In the optimization, the intelligibility of the particular test words was equalized.
The evaluation of the test with 147 primary school pupils with normal hearing in silence and 107 pupils in noise is presented in this article. The comparability between test lists for speech intelligibility was investigated and age dependent reference functions were determined.
The evaluation showed that intelligibility differences are larger across children within one grade than across different test lists. The reference functions of first grade pupils are shifted to slightly higher presentation levels and signal-to-noise ratios both in silence and noise.
The 12 optimized test lists of the OlKi test are equally intelligible both in silence and noise. No list effects are expected. The degree of difficulty of the Oldenburg children's rhyme test can be compared with the Göttingen children's test II and the Mainz children's test III.
奥尔登堡儿童韵律测试（OlKi）是为在安静环境下测量小学生的言语可懂度而设计和优化的[8, 3]。在优化过程中，特定测试词的可懂度得到了均衡。
本文介绍了对147名听力正常的小学生在安静环境下以及107名小学生在噪声环境下进行该测试的评估情况。研究了言语可懂度测试列表之间的可比性，并确定了与年龄相关的参考函数。
评估表明，同一年级内儿童之间的可懂度差异大于不同测试列表之间的差异。一年级学生的参考函数在安静和噪声环境下均向略高的呈现水平和信噪比偏移。
OlKi测试的12个优化测试列表在安静和噪声环境下的可懂度相同。预计不存在列表效应。奥尔登堡儿童韵律测试的难度程度可与哥廷根儿童测试II和美因茨儿童测试III相比较。
