Vibro-acoustic analysis of cellos using the finite and boundary element methods and its application to studies on the effects of endpin properties

In this paper, an improved vibro-acoustic analysis method for cellos is presented. The soundpost and endpin are physically modeled as ordinary beams. cello box, bassbar, bridge, neck shells. Their governing equations numerically analyzed by the finite element method, yielding equation of motion total multi-degree-of-freedom system. radiated sound field around box dealt with using normally differentiated Kirchhoff–Huygens integral equation, which boundary method. All vibration fields fully coupled. proposed validated through measurements a cello. As application developed numerical authors investigate effects properties.
