Research on Human Auditory Information Processing
|
高次情報通信システムを構築のために不可欠となる研究
※高次情報通信システム：
「いつでも，どこでも，だれとでも」というバリアフリー通信，マルチメディア通信といった，
人間を情報の発信および受信源とするシステム
|
|
In our laboratory,
the process of sound localization is studied based on measurements and hearing tests.
|
|
We are aiming at understanding the process in the human auditory system
to extract distinctive characteristics of a sound.
|
|
We are studying about two themes.
One is the interaction between speech perception and talker's face motion.
The other is the interaction between auditory information and self-motion perception.

Realization of Advanced Acoustic Communication Systems
|
人間の聴覚情報処理に関する知見を用いて，
誰でもがどんな環境でも快適に通信できる音環境・高度な音響通信システムの実現を目指す研究
|
|
We are studying on the auditory display systems which provide realistic virtual 3D sound space.
|
|
We are also studying about the evaluation method how a hearing aid
is suited to individual hearing impaired listener.
|
|
We are developing new algorithms of digital audio watermarking,
by which information of copyrights can be embedded into
digital data without perceivable sound distortions.
