| Abstract: | In this paper, the acoustic cross_power spectrum properties of the fracture bone in tapping vibration is analyzed and studied . The peak frequencies of acoustic cross_power spectrum of left and right limbs of healthy man is the same, and the frequency range is from 132 to 145 Hz. The high frequency response is reduced after fracture. The more serious grosser the bone fracture, the smaller the peak frequency of cross_power spectrum. Variation of peak frequencies between normal and fracture limb decreases with fracture healing. Making a comparison of the peak frequency of the normal and fracture limb may assess the fracture healing and provide an important approach for noninvasive, quantitative and objective assessment fracture healing. |
