PROBLEM TO BE SOLVED: To estimate a hearing experience of a music, based on a brain wave measured when a user was hearing the music.SOLUTION: A music hearing experience presence/absence estimation method comprises: a step S10 for measuring a brain wave of a subject who is hearing a music which a user cannot understand whether or not the user has heard the music, for acquiring subject brain wave data a step S22 for acquiring a first feature which is related to a measurement position and intensity of the brain wave, based on the subject brain wave data and a step S30 for collating the first feature with a model brain wave pattern which is a pattern of a measurement position and intensity of the brain wave which is generated with dependence on at least one of a state when a user is hearing a known music and a state in which a user is hearing an unknown music, and which is created using first data which is data acquired by measuring the brain wave of a person who is hearing a known music which the person understands that the person has heard the music, and second data which is acquired by measuring the brain wave of a person who is hearing an unknown music which the person understands that the person has not heard the music, then using the collation result, for estimating presence/absence of the music hearing experience.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】楽曲の聴取時に計測した脳波に基づきその楽曲の聴取経験を推定する。【解決手段】楽曲聴取経験有無推定方法では、聴取経験の有無が不明な楽曲を聴取している被験者の脳波を計測して被験者脳波データを取得するステップS10と、被験者脳波データから脳波の計測位置及び強度に関する第1特徴を取得するステップS22と、第1特徴を、聴取経験があると判明している既知楽曲を聴取している人の脳波を計測して取得したデータである第1データ及び聴取経験がないと判明している未知楽曲を聴取している人の脳波を計測して取得したデータである第2データを用いて作成された、既知楽曲を聴取している状況及び未知楽曲を聴取している状況の少なくとも一方に依存して発生する脳波の計測位置及び強度のパターンであるモデル脳波パターンと照合して得られた照合結果を用いて、楽曲の聴取経験の有無を推定するステップS30とを含む。【選択図】図4
