World of Sound and Vibration Analysis and Simulation

Suzuki Laboratory, Department of Information and Network Science
Chiba Institute of Technology

Sound and vibration analysis and simulation are the main topics in Suzuki Laboratory, which started in 2000. This website introduces the past (including Suzuki's work before 2000) and present main topics and members of Suzuki Laboratory.
