The 2nd Xi’an Acoustics Conference was held on December 18, 1990 in Xi’an. The conference was sponsored by Xi’an Acoustics Society. Meeting a total of 36 papers. The report is extensive and covers acoustic signal processing. Medical Ultrasound and Ultrasound Diagnosis, Noise Control and Building Acoustics, Power Ultrasound and Ultrasound Testing. The meeting is characterized by: new content, high level. Professor Ma Yuanliang discussed the recent developments in artificial neural network (ANN) research. Based on the current understanding of the human nervous system, the electronic network structure and adaptive system similar to the human neural network system are introduced. Based on the different levels of perception, cognition and behavior control and the simulation of various functions of the human brain, ANN function of the computer and the current cutting-edge issues in this area. Professor Zhang Aihong reported color Doppler ultrasound in the diagnosis of peripheral vascular disease. Professor Dong Yanwu
