Hideyuki Nomura
Professor, Graduate School of Informatics and Engineering

Hideyuki Nomura specializes in acoustic electronics. While traditional acoustics research focuses on applications such as speech recognition and media processing for listening purposes, Nomura's group explores acoustic technology development without the goal of listening. They work across a wide frequency range, from audible to ultrasonic frequencies, to improve our lives.

Recent research highlights
Acoustic Imaging: Sound waves are used for visualization, particularly vibro-acoustography, which captures the mechanical characteristics of objects by inducing transient response vibrations.

Medical Applications: Acoustic imaging finds applications in medical fields, including ultrasound diagnostics and therapeutic treatments. They aim to assess the safety and distribution of acoustic energy within the body.

Directional Audio: Nomura's group is working on directional audio systems, such as parametric speakers, which can transmit sound in specific directions. They have developed a technology to maintain directionality while stopping sound propagation, which can prevent reverberation in confined spaces.

Overall, their research combines acoustic phenomena and electronics to enhance our quality of life. They plan to incorporate artificial intelligence and other technologies for the development of next-generation acoustic systems in the future.
