| Outline of Final Research Achievements |
This research project aimed to establish fundamental technologies to make it possible for everyone to enjoy sound field control, by constructing acoustic transfer characteristics control method without depending on room facilities and reverberation situation.
First, comfortably simultaneous measurement method was introduced for the acoustic transfer characteristics betewwn multiple control points and multiple loudspeakers. Next, the research representative conducted a fundamental research on the modeling of the impulse response, and obtained knowledge on the reverberation structure and phase correction included in the transfer function matrix. Furthermore, to improve the reverberation durability in the sound field control method, a new sound field personalization which extended wave field synthesis was developed. In addition, certain results were obtained on the sound reproduction method of masking including the sound localization information.
