Abstract

Bending a human joint generates a sound. This paper theoretically tackles the cracking sound generated by the manipulation of human joint such as finger. The Rayleigh-Plesset equation in the classical bubble dynamics is applied to determine the nonlinear oscillations of bubble that generates sound. Comparing the numerical solutions of the Rayleigh-Plesset equation for two types of modeling, i.e., forced- and free-oscillator assumptions for inhomogeneous terms, gives clear difference.
