The purpose of this work is to realize a human sensibility system for timbre of a Japanese traditional flute, "Nohteki". Two approaches are used for several data sampling about timbre. One is the evaluation of the physics characteristics about "Nohteki" sounds with time, spectrum analysis, and wavelet transform. The other is the evaluation of the sensibility about "Nohteki" sounds through the questionnaire. At first, several axes to explain the important factors are found with factor analysis from the sensibility of listeners about "Nohteki" sounds by SD method. Evaluate equations between the effective physics values as input parameters and the sensibility factors as output parameters are established by using multiple regression analysis. Furthermore, the non-liner relation of the sensibility is considered by using a neural network, the correlation between the sensibility of listeners and the physics values of "Nohteki" sounds is clarified. As a result, it can be said to realize a human sensibility system for timbre of "Nohteki".
