    Abstract: Disclosed is an acoustic analysis apparatus. The acoustic analysis apparatus is configured to allow a user or operator to set a plurality of load input points corresponding to respective sound input sources, and an evaluation point for evaluating a level of a sound pressure transferred from each of the set load input points (S1 to S3). Then, the acoustic analysis apparatus is operable to calculate a sound pressure level-frequency characteristic of a sound pressure from each of a plurality of paths between respective ones of the load input points and the evaluation point, by a finite element method (S5), and display the sound pressure level-frequency characteristic obtained by the calculation, in such a manner as to distinguishably indicate a difference in sound pressure level between the respective sound pressures from the paths.
