| Research Abstract |
In this research, the goal is to achieve a new sound image reproduction method which reproduce different sounds to multiple users in the same space. First of all, easy and fast measurement method of room acoustic transfer characteristics was developed, which a normal user can set up the loudspeaker array system easily. As a result, the principal investigator have found a method that can measure the acoustic transfer characteristics at all channels simultaneously by using normal music.
Next, in the sound reproduction system based on inverse filtering, the principal investigator worked on achievement of individual sound image generation in the under-determined conditions. As a result, the system can be realized with robustness against user's head movement. Further, a personal sound reproduction system based on the integration of the NBSFC filters and loudspeaker array was proposed, and the principal investigator proved to expand for multiple users by parallelizing the system.
