PROBLEM TO BE SOLVED: To provide a vehicle acoustic analyzer for obtaining a sound pressure characteristic distribution in a predetermined acoustic frequency range, and implementing detail analysis at a specified frequency. SOLUTION: A plurality of load input points corresponding to a sound input source are set, and an evaluation point of a sound pressure of the sound transferred from each load input point is set (S1-S3). The frequency characteristics of the sound pressure on each path between a plurality of the load input points and the evaluation point are calculated by a finite element method (S5). The frequency characteristic of the sound pressure on each path is displayed and obtained by a calculation so as to express the difference between the sound pressures at frequencies on the paths.
