| Abstract: | Based on vocalism principle of muscle,muscle tone characteristics of quadriceps femoris at different load were researched by means of acoustic methods. The wavelet processing program and power spectrum analysis program were written by the aid of Matlab7.0 software to process,analyze and research the extracted audio signals of muscle. vocalism rules and charac-teristics of the muscle are revealed in this paper. A new method and basis are provided for muscle strength training and re-search,and an analytical means for non-destructive detection of muscle ache and sprain. |
