| Outline of Final Research Achievements |
The greatest achievement of this research result is being the first one of its kind to elucidate the types and physical characteristics of the sounds perceived by migraine patients as unpleasant in daily life. Furthermore, we clarified the relationship between the auditory threshold measured by psychological experiments and the auditorily evoked response measured by physiological experiments, thereby advancing our understanding of perceptual mechanisms in migraine patients. These results serve as basic data not only for designing a device enabling the simple diagnosis of migraine by having a patient listen to sound, but also for treating migraine and providing a comfortable sound environment for migraine patients. This finding can thus prove instrumental in the fields of medicine and engineering for improving the lives of patients.

| Academic Significance and Societal Importance of the Research Achievements |
既存研究では，片頭痛患者に単純な音刺激を聴取させた時の心理評価や生理反応の計測に留まっていた。これに対し，本研究では，片頭痛患者が日常生活で聴取する複合的な音を対象としたことで，不快ノイズとして感じる音の種類と物理特性を明らかにし，片頭痛患者の心理・生理反応メカニズムの本質的な解明を前進させた点で，学術的意義があるといえる。また，問診による片頭痛患者の診察が音刺激の提示により簡易的に行える技術基盤や片頭痛患者に快適な音環境を設計する技術基盤が整備され，片頭痛を抱える多くの患者に対する新たな医療・生活支援の提供につながる点で，社会的意義が大きいといえる。
