Abstract: An acoustic characteristics optimization model analysis apparatus includes a finite element model generation unit; a boundary element model generation unit; an acoustic transfer function calculation unit; a nodal point association unit; and a sound pressure calculation unit that incorporates the plurality of nodal points of the finite element model correlated with the plurality of nodal points of the boundary element model by the nodal point association unit into the acoustic transfer function calculated by the acoustic transfer function calculation unit to calculate a sound pressure transmitted from the finite element model to the predetermined position.
