Seoul National Univ. Acoustics & Vibration Lab.

Seoul National Univ. Sound & Vibration Lab.

The sound and vibration(S&V) laboratory at SNU was established on March, 1997. After Advanced Automotive Research Center (AARC) was built on June, 2004, we started to actively utilize AARC facilities and equipment to conduct our researches focused on NVH automotive engineering. So far, we have been constantly promoting the industry-academy cooperation projects to carry on our researches.
In this respect, our lab has exceptionally enhanced the reputation of SNU and we are still contributing extraordinarily as evidenced by publications, citations, and other criteria in this field.
