PROBLEM TO BE SOLVED: To provide a sound visualizing apparatus which can evaluate mixed sound. SOLUTION: A result of a frequency analysis applied to the mixed sound is shown in the figure (a), and frequencies and brightness of visible light are allocated so as to correspond to the frequency analysis result in the figure (b). An orange-color screen 22 emits light brightly, and an indigo-color screen 26 and a purple-color screen 27 emit light darkly as shown at (c) in a display section 17. Since a correlation between sounds and colors is made strong, an observer can visually recognize height of the sound more easily. The mixed sound in which a high-pitched sound is thereby with a low-pitched sound, is displayed by replacing it with the visible light, and as a result, the mixed sound can be evaluated easily.
