We aim to develop advanced and comfortable acoustic communication systems exploiting digital signal processing techniques. To realize this, we are keenly studying the information processing that takes place in the human auditory system. Moreover, we also investigate the mechanisms for multimodal information processing, including hearing. We mainly apply a psycho-acoustical approach to study human auditory and multimodal perception. In this sense, our research is characterized by its high interdisciplinary nature which covers acoustics, information science, communications engineering, electronics, audiology and psychology.
Advanced Acoustic Information Systems (Prof. Suzuki)
Basic studies are keenly conducted to gain a deeper understanding of the perceptual process of hearing. In particular, three-dimensional (3D) spatial hearing is studied under the notion of “active hearing.” This notion treats 3D spatial hearing which considers listener’s movement during hearing. With this knowledge as a basis, we aim towards the realization of a ‘comfortable’ 3D sound environment. A notable application of this research is the development of 3D auditory displays. These systems are a critical requirement for the realization of universal multimedia communications.
- Spatial hearing process as a multimodal perception
- System theory and development of 3D highdefinition auditory displays based on the notion of “active listening”
- Development of new theories of acoustic digital signal processing.
- High level cognition process of the sense of presence and verisimilitude
Auditory and Multisensory Information Systems (Assoc. Prof. Sakamoto)
We study the mechanism of human multimodal processing, including hearing. In particular, we focus on speech perception as an audio-visual process, the judgment of auditory space during motion and the impression of a sense-of-reality in multimodal content. Such knowledge is crucial to develop advanced communication and information systems. Based on this knowledge, we are developing future auditory information systems.
