"Why should people talk louder in cars driving at over 100km/h than those who are walking?"

Welcome to Daehan Solution hompage.

Since its foundation in 1982, Daehan Solution prioritized human, environment, and customer satisfaction to provide Total System Engineering, which includes N.V.H. of automobiles, ranging from testing, diagnosis and prescribed design to production for reducing internal and external noise in relation to automobile noise and vibration.

We are not satisfied with the improvement of ride quality by simply reducing internal and external noise of automobiles, but we continue endless research and development in order to present satisfaction beyond comfort to all customers by redesigning rough noise into pleasant sound.
