Sound Quality Issues in the High Efficient, Low Pollution Energy Vehicles

고효율, 저공해 에너지 이용 차량의 음질 이슈

In enhancing the technologies for the highly efficient and low pollution vehicles, the emitted sound by applying those techniques is degraded, which needs further vibro-acoustic tuning. The point of concern is usually related to the sound quality, and, sometimes, to the direct connection with the pedestrian safety. In this talk, a brief discussion is given to the sound quality issues on the start-stop function, cylinder-on-demand, engine down-sizing, turbo-chargers, road noise, and artificial warning sound.
