摘要

Sound transfer functions of bones were measured in vivo and in vitro with two accelerometers. Experimental results show that bones behave as a sound low-pass filter, and vibrate in several modes. Characteristics of sound traasfer function vary with individuals, but data obtained in both legs of one person are comparable. The resonant frequency of the sound transfer function indicates the size of defect in bone well, so it can be used for diagnosis of bone disease and assessment of fracture healing.
