自闭症谱系障碍儿童听觉统合训练敏感频段初步分析

目的初步分析自闭症谱系障碍患儿在听觉统合训练系统中的敏感频段分布情况。方法选取2018年1月至2018年8月医院收治的44例自闭症谱系障碍患儿,患儿均进行听觉统合训练。通过听觉统合训练的检测模块频段测评功能评估,初步分析敏感频段分布特点,并为后续敏感频段的脱敏治疗提供针对性指导。结果患儿的检测模块敏感频段分布分别为100～250 Hz(7.97%)、500～4 000 Hz(57.97%)、6 000～12 000 Hz(32.25%)和16 000Hz(1.81%),500～4 000 Hz和6 000～12 000 Hz为患儿的主要敏感区段。500～4 000 Hz是语言清晰度的分布频段,6 000～12 000 Hz是影响乐器及外界声音音色的频段。结论自闭症谱系障碍患儿主要是在语言和乐器的清晰度方面存在感知失调。

Preliminary analysis of sensitive frequency band of auditory integration training in children with autism spectrum disorder

Objective To preliminarily analyze the distribution of sensitive frequency band of auditory integration training in children with autism spectrum disorder. Methods From January 2018 to August 2018, 44 children with autism spectrum disorder were selected, and they all were given auditory integration training. The distribution characteristics of sensitive frequency band was preliminarily analyzed by the frequency band measurement functional evaluation in detection module of auditory integration training, in order to provide targeted guidance for the follow-up desensitization treatment of the sensitive frequency band. Results The sensitive frequency band in the detection module of children were 100-250 Hz (7.97%), 500-4 000 Hz (57.97%), 6 000-12 000 Hz (32.25%) and 16 000 Hz (1.81%) respectively;in which, 500-4 000 Hz and 6 000-12 000 Hz were the main sensitive frequency bands. 500-4 000 Hz was the frequency band of language clarity, and 6 000-12 000 Hz was the frequency band that affected the sound and color of musical instruments and external sounds. Conclusion Children with autism spectrum disorder mainly have perceptual disorders in the clarity of language and musical instruments.
