Confront the vibrations and sounds around you! - Discern the good from the bad -

Keywords: seismic resistance, seismic isolation, vibration isolation, sound, brain waves, electromyography, sports

The research fields are broad, including quiet engineering, seismic and vibration engineering, acoustics, sports engineering, and bioinformatics. In general, the research focuses on vibrations, sounds, and movements. Vibrations and sounds exist in our daily lives. Some of them can be harmful to us, while others enrich our lives. For example, the earthquakes that have been frequent in recent years have caused damage to people and structures. Additionally, harmful vibrations and noise are generated in factories, automobiles, railways, aircraft, and countless other sources. On the other hand, there are also many applications that utilize vibrations. Various uses of vibrations include transportation, rock drilling machines, and in the realm of sound, music and alarm sounds, among others. Harmful vibrations and sounds should be reduced, while usable vibrations and sounds should be effectively utilized. This requires understanding their characteristics through observation and measurement, modeling and simulation, as well as establishing design guidelines and evaluating human perception and sensitivity. Currently, research is being conducted on increasing rigidity by twisting thin plates and evaluating human comfort using brain waves.
