Abstract
The acoustic performance of acoustic materials is readily studied for various values of the material parameters characteristic of acoustic materials. An acoustic performance calculation device is provided with an acoustic performance calculation device that calculates the acoustic performance of acoustic materials for each of a plurality of values in a pre-specified numerical range for each of a plurality of material parameters characteristic of acoustic materials based on a mathematical model for mathematically representing acoustic material, a contour map drawing device for drawing a contour map representing the calculated acoustic performance by contours where the two axes are the values of one material parameter and the frequency, and a plot drawing device for plotting the performance curves showing the relationship between the frequency and the acoustic performance for one value in the numerical range.
