Vibration and Acoustics

Vibration and Acoustics Laboratory in Department of Engineering Physics, ITS learn about the phenomena of sounc and vibration, including human hearing system and its applications e.g. speech shynthesis, noise mapping, vibration analysis, and many more.

Beside research, Vibrastic lab also provides consultation about vibrations and acoustics, including indoor acoustics, vibrations analysis, speech shynthesis, so that Vibrastic lab is able to compete with another professional consultant.

Vibration and Acoustics Laboratory is certified as LBE (Lab Based Education) by JICA through ITS – Preditc2 JICA Project.
