Genesis is the first luxury premium sedan of Hyundai, designed to compete in the world market. Naturally, the car is to provide a high level of acoustic comfort for cabin occupants. One of the aspects in achieving this goal is the reduction of underbody wind noise, the source of which is difficult to locate. The company has been developing acoustic holography for locating noise sources in its anechoic wind tunnel for years. The technical aspects of underbody acoustic holography and how it was applied in the development of Genesis will be introduced.
