Several vibration-isolating equipments with metal spring, air spring, rubber spring and an oil damper are developed. The purpose of this paper is to study the vibration and noise of the engine that is reduced by new mount-system (duffing's mount) using magnet-spring. At this study, an experimental device with the engine was created in order to measure the vibration and sound pressure level of the engine. The vibration was measured with acceleration pick-up and the noise was measured with sound level meter. In this study the new mount-system using magnet-spring was compared with rubber mount. The new mount-system using magnet-spring can reduce the vibration and solid borne sound of the engine rotation.
