Report on Research Projects on Head-Related Transfer Functions and Virtual Auditory Displays in China

摘要

Head-related transfer functions (HRTFs) and virtual auditory displays (VADs) are popular research topics in the areas of acoustics, signal processing, and hearing, among others. In addition, HRTFs and VADs have been widely applied in numerous fields such as multimedia and virtual reality, communication, computer games, acoustical design in rooms, and spatial sound reproduction. In recent years, these topics have received increasing interest in China. The current engineering report presents the highlights and developments of our research projects, including studies on HRTF measurements and database construction, statistical analysis on measured HRTFs, a dynamic VAD system, and algorithm for reducing timbre coloration on the virtual surround sound reproduction. Finally, suggestions for further studies are also presented.
