| Summary: | 碩士 === 國立交通大學 === 電子工程系 === 90 === Head Related Transfer Function (HRTF) is one of the major topics in 3D audio processing. This function describes the change both in time and frequency domain when a sound event comes from different direction being reflected by head, pinna and torso of the listener. This study intends to measure the transfer function with considerations on the influence of the distance of sound source and the indirect sound in a common diffuse field.
The main purposes of this thesis are: (1) Construct a through and effective HRTF measurement process in a reverberant environment. (2) Measure both Far Field and Near Field HRTF and its associated Binaural Room Impulse Response (BRIR). Study the changes in directional and distance cues at different distance and direction in the horizontal plane. (3) Design and Implement two HRTF analysis and synthesis platforms with friendly Graphical User Interfaces (GUI) to use the content of database. (4) Propose two algorithms to synthesize Near Field and Far Field spatialized sound. Discuss the possibility of synthesizing the Near Field spatialized sound based on the Far Field HRTF with proper cues such as indirect sound, auditory parallax, and reverberation/direct sound pressure level.
