摘要

PROBLEM TO BE SOLVED: To objectively and comprehensively evaluate the total quality by collecting a plurality of objects.;SOLUTION: In derivation processing of a total evaluation value estimation formula, an input part 6 inputs sound pressure of each engine sound measured by a noise meter 2. A partial evaluation value determination part 7 determines a psychological sound evaluation value of each engine sound and creates a measurement value map expressing relation among fuel injection quantity, a rotational frequency and the psychological sound evaluation value in each operation condition. A first analysis part 8 creates a least squares plane of the measurement value map in each operation condition. A physical quantity determination part 9 determines first to third physical quantities based on the measurement value map and the least squares plane. A second analysis part 10 derives the total evaluation value estimation formula by using a predetermined total evaluation value which is a subjective evaluation value of the total quality of a plurality of engine sounds in each operation condition and the first to third physical quantities.;COPYRIGHT: (C)2013,JPO&INPIT
