Diagnostic of central auditory processing should be done in some group of children, especially with learning disabilities.
The audiological examination was performed in the group (n=24) of pupils from first class of secondary school (13-14 years) without any otological and neurological problems. The battery of audiological tests was used: pure tone, impedance and speech audiometry, two tests with low redundant speech: filtered speech (FS) and compressed sentences, sequencing tasks (FPT, DPT) and ABR. Normal answer: in FS - 80% correctly repeated words, FTP and DPT 75% correctly repeated sequences.
Results of this examination were referred to the scores of test after primary school (max 40 points). Children were divided into 3 groups: group III (33-40 points), group II (21-32), group I (0-20). Because seven children havenít had stapedial reflex we put them into special group - NR group. Tympanometry and pure tone audiometry were normal in all children. Speech audiometry was performed in intensity 30dB and correct answers were repeated in 80-100%. In compressed sentences test answers of 22 children were normal. The average dyscrimination score were: FS g. III 90%, g. II 84,3%, g. I 77,5%; FPT 89,2%, 72,9%, 62,5%; DPT 82,5%, 71,4%, 62,5%. The percentage of normal answer were: FS g. III 100%, g. II 100%, g.I 75%, FPT 100%, 42,9%, 25%, DPT 66,7%, 42,9%, 25%. The comparison between group I-III and NR was performed. The average dyscrimination score FS g. I-III 84,7%, g. NR 71,4%; FPT g. I-III 76,2%, g. NR 72,1%; DPT g. I-III 73,5%, g. NR 50,7%. The percentage of normal answer were: FS g. I-III 94,1%, g. NR 42,9%; FPT g. I-III 58,8%, g. NR 28,6%, DPT g. I-III 47,1%, g. NR 28,6%.
In central auditory tests (FS, FPT, DPT) worse results were in children without stapedial reflex. Good pupils (group III) had better results than poor ones (group I). The better results in audiological tests, the better scores in school test.
中枢听觉处理诊断应在部分儿童群体中进行，尤其是有学习障碍的儿童。
对一组（n = 24）来自中学一年级（13 - 14岁）且无任何耳科和神经问题的学生进行了听力学检查。使用了一系列听力学测试：纯音、声阻抗和言语测听、两项低冗余言语测试：滤波言语（FS）和压缩句子、序列任务（FPT、DPT）以及听性脑干反应（ABR）。正常答案标准：在FS测试中，80%的单词正确重复；在FTP和DPT测试中，75%的序列正确重复。
此次检查结果与小学毕业后的测试分数（满分40分）进行对比。儿童被分为三组：第三组（33 - 40分）、第二组（21 - 32分）、第一组（0 - 20分）。由于七名儿童没有镫骨肌反射，将他们归入特殊组——无反射组（NR组）。所有儿童的鼓室图和纯音听力测试均正常。言语测听在30dB强度下进行，正确答案重复率为80 - 100%。在压缩句子测试中，22名儿童的答案正常。平均辨别分数分别为：FS测试中，第三组90%、第二组84.3%、第一组77.5%；FPT测试中，89.2%、72.9%、62.5%；DPT测试中，82.5%、71.4%、62.5%。正常答案的百分比分别为：FS测试中，第三组100%、第二组100%、第一组75%；FPT测试中，100%、42.9%、25%；DPT测试中，66.7%、42.9%、25%。对第一至三组与NR组进行了比较。平均辨别分数：FS测试中，第一至三组84.7%、NR组71.4%；FPT测试中，第一至三组76.2%、NR组72.1%；DPT测试中，第一至三组73.5%、NR组50.7%。正常答案的百分比分别为：FS测试中，第一至三组94.1%、NR组42.9%；FPT测试中，第一至三组58.8%、NR组28.6%；DPT测试中，第一至三组47.1%、NR组28.6%。
在中枢听觉测试（FS、FPT、DPT）中，没有镫骨肌反射的儿童结果较差。优秀学生（第三组）的结果优于成绩差的学生（第一组）。听力学测试结果越好，学校测试成绩越高。
