Abstract

<p>The sound quality of a classical guitar is greatly influenced by the Sounding Board. Strutting is attached to the back of the Sounding Board to maintain strength. At the same time, it is known that the strutting layout has a great influence on the sound quality of the guitar. Today, the layout of strutting tends to be fixed. Therefore, we made a guitar with a characteristic by reducing the number of strutting. However, the professional player's evaluation was "uninteresting sound quality<tt>“</tt>. Therefore, we applied a one-week light aging effect to the guitar by acoustic vibration. In this evaluation, the sound quality was evaluated by the combination of sound extension and timbre. In addition, the expression of the timbre can be calculated from many combinations of excitation positions and excitation methods. This guitar had better Sound extension than the conventional guitar even in the light aging state. In addition, this guitar can be evaluated as having a wide range of tones and excellent sound quality, and the same results as the hearing evaluation of professional players were obtained.</p>
