Outline of Final Research Achievements

We developed a screening test and an objective test that can contribute to early detection, paying attention to the deficit of hearing in noise of Auditory processing disorder that causes difficulty in listening even though the hearing ability is normal. First, for the screening test, a simple test using four sound sources with gradually increasing noise was created, and standard data of elementary school students who had no problem in listening were obtained, and the effectiveness in the clinical group was also confirmed. For the objective hearing test, we developed a P300 EEG measurement system that can adjust the stimulating sound and noise, and confirmed that in normal hearing subjects, when the noise increased, the hearing loss decreased objectively.
Then, a “pediatric listening outpatient service” was opened at a university hospital and continued to provide physical and mental support through team medical treatment.

Academic Significance and Societal Importance of the Research Achievements

聴覚情報処理障害（APD)に対し、欧米では評価と支援が標準化されているが、わが国ではまだ確立されていない。APDは発見が遅れると二次的に学習面、心理社会面に問題をきたすことがあるため、早期発見と支援が必要である。本研究において、短時間で集団実施が可能なスクリーニング検査が開発できたこと、他覚的検査による客観的評価の可能性が検討できたことの意義は大きいと考える。また、小児の聴こえの問題に対し、多職種協働で心身両面からケアする一つの支援システムモデルを形成できたと考える。
