Recently, the sound and viblation analysis on computers are ubiquitous. The degree of freedom of figure model for analysis are increasing year by year. By the performance of the present analysis technique and capability of a computer, It is difficult to sound as actual sound from the result of analysis. It is unsatisfactorily for referring to the result of an experiment and obtaining. However, desiners are looking forward to reprocudt the sound from analysis results and they expects the computer will be stronger more than current. So, we have to prepare how to design the sound of structures. In this research, We process making a hole, a rib, a patch, bending, on figure model. We search how it change the low frecquancy part of the sound and the middle frequency of the sound.
