Vehicle Interior Sound Quality

Yansong Wang has been engaged in teaching and scientific research on vehicle sound quality evaluation and control for many years and has achieved significant progress in vehicle NVH technology, environmental noise evaluation and control, acoustic material testing and noise reduction equipment. In basic theoretical research, he proposed several intelligent evaluation methods for non-stationary signals, established intelligent evaluation models of noise comprehensive annoyance based on psychoacoustic parameters, and proposed a hybrid vibro-acoustics active control method for interior sound quality. Prof. Wang has successively completed more than 40 various scientific research projects, including 4 projects from the National Natural Science Foundation of China, and has won more than 10 scientific research awards; he is the author of more than 170 papers/books/book chapters, he is currently a Member of the IEEE, IIAV Society, China Ordnance Society, China Society of Automotive Engineering, China Society for Environmental Sciences and the Acoustics Society of China. Hui Guo has been engaged in teaching and scientific research on vehicle sound quality evaluation and control for years and has achieved significant progress in vehicle NVH technology, acoustic metamaterials and piezoelectric metamaterial. He proposed several intelligent evaluation methods for psychoacoustic parameters, and proposed material/structure design and optimization methods for acoustic metamaterials. Prof. Guo has successively completed more than 30 projects from the industrial circles, and has won more than 3 scientific research awards; he is the author of more than 70 papers, he is currently a Senior Member of China Society of Automotive Engineering and International Institute of Acoustics and Vibration. Chao Yang has been engaged in teaching and scientific research on vehicle sound quality evaluation and control for many years. Dr. Yang proposed various novel methods for reconstructing the vehicle interior noise signal, which improved the effect of active sound quality control. He has completed more than 10 scientific research projects, including two projects from the National Natural Science Foundation of China and nine business cooperation projects. In the past decade, he has published more than 30 SCI papers.
