Study of Novel Sound Detection TCM Pulse State Sensing Mode

This paper investigates a kind of Chinese Traditional Medicine (TCM) pulse state diagnosis sensor which is based on sound detection. This method has many advantages and is in line with the TCM pulse state multi-attribute characteristics. First the sound measurement method was designed. Then the verification experiment of electret microphone was studied. The experiment results shown some electret microphones are available for low frequency and low energy vibration signal which is similar to TCM pulse state signal measurement. Eventually it comes to the conclusion that this pulse acquisition mode is available method and can effectively reveal the different kinds of pulse signal characteristic differences. Boys and girls TCM pulse state signal were detected separately. It shows that Different gender has different pulse state and the pulse shape is also different.
