Design and Experiment Study for Acquisition System of the Children Lung Sound Signal

Abstract:

Lung sound contains a wealth of information on organ function and pulmonary physiology and pathology status information, and lung sounds auscultation has become a useful clinical tool in the diagnosis of lung disease. Therefore, lung sound acquisition system is designed using STM32 microcontroller as the master chip. The system uses a stethoscope and electret microphone with signal processing circuit and system flow chart is also given. Finally related experiments is done based on designed system, the results show that: the design of the system can stabilize unmistakable signal acquisition lung sounds.
