This study address that the effect of the sound which helps to cure autism through measuring acoustics
parameters and ratio of brain-wave energy. Various existed studies about the solution of psychotherapy
using the sound parameters. especially, There are various studies about the solution of autism and
depressive disorder treatment using the sound. However, these previous studies have put more weight on
external behavior change such as nictation, conversation, or etc. Such research method has some difficulties
to make objective decision if external behavior changes are just habits or some kinds of manners. Thus,
this study is for conducted to observe the changes objectively to analyze the effective sound for autism
treatment, first step psychological impacts into the process of sound psychological help after being selected
by multiple parameters analysis and second step of patients with EEG changes in the age of autism, after
measuring accurate measuring brain wave. The measuring ratio of brain wave can be easily drawn through
internal body transformation only, so this method can come with objective and the least biased result. The
suggested method concludes that rate changes in brain wave energy derived the meaningful result.
