On April 11, 2020, Shenzhen sound industry association, together with acoustic building forum and online and offline training institutions, carried out online public electroacoustic technology lecture training through "Tencent conference app" online meeting and live training. It is the fifth activity that has been carried out. Professor Sun Guangrong, a doctoral director of Nanjing University, gave a lecture on "room acoustics".
About Professor Sun Guangrong
In 1956, he graduated from the Department of physics of Nanjing University and stayed in school to teach. He used to be vice director of Institute of acoustics, Nanjing University, director of Department of Electronic Science and engineering and director of Department of information and electronics of Jinling University (1990s). Special allowance from the State Council. He once served as the vice chairman of the national electroacoustic Standardization Technical Committee, the member of the National Acoustic Standardization Technical Committee, the member of the academic committee of architectural physics of the Architectural Society, the Deputy Secretary General of the Council of the acoustic society, the vice chairman of the acoustic society of Jiangsu Province, and the standing director of the Environmental Science Society of Jiangsu Province, and served as the drafter of many national acoustic standards. Engaged in the research of architectural acoustics, electroacoustics and environmental acoustics, published more than 50 academic papers; published acoustic design principles of anechoic room and reverberation room (Science Press, Beijing, 1981), noise measurement and control (Jiangsu Science and Technology Press, Nanjing, 1985), environmental acoustics Foundation (Nanjing University Press, Nanjing, 1995). It has won one third prize of national science and technology progress award, and five second prizes of science and technology progress of Ministry of education, Ministry of electronics and Ministry of culture.
In this lecture, Mr. Sun emphasized the importance of environmental acoustics foundation for the design and application of anechoic room, reverberation room and loudspeaker test box. The room frequency response and normal vibration mode, reverberation time, indoor steady-state sound field, sound-absorbing material and structure, anechoic room and reverberation room, loudspeaker test box, etc. are described respectively. With the consent of Mr. Sun, the PPT of this lecture is released for your reference and study. Thank you for your selfless dedication!
