Low Vibration and Noise Body
Low Vibration and Low Noise Body1. General
Effective application of vibration damping and noise suppressant materials reduces engine noise and road noise.
2. Sound Absorbing and Vibration Damping Materials
^ The locations of the sound insulation materials in the frame cross sections have been optimized, creating a quiet drive.
^ A felt type absorption material has been provided on the back of the cowl top panel and a reinforcement has been provided at the bottom to ensure quietness.
^ An acoustic film has been provided between the laminated layers of windshield glass to ensure quietness.
^ The main weatherstrip and the No.2 weatherstrip on the front and rear doors have been composite formed. Each of the weatherstrips surrounds the entire door, and a sponge layer has been provided outside of the No.2 weatherstrip in order to reduce the reaction sound that is created when the door is closed.
^ Weatherstrips have been provided on the rocker panel molding in order to reduce the reaction sound that is created when the door is closed.
^ A rear wheel housing liner and a front floor cover have been provided to reduce the sound created by flying sand and road noise.
^ Asphalt sheets made of different materials and thicknesses have been optimally allocated on the floor to reduce road noise.
^ Sound absorption and insulation materials have been provided in the various areas of the cabin to ensure quietness.
^ A silencer has been provided at the outer cabin side of the floor tunnel for quietness.
3. Reducing Wind Noise
Wind noise has been reduced through the adoption of the following constructions.
^ On the front and rear doors, the offset between the door window frame molding and the door glass has been decreased.
^ The windshield outside molding is used to minimize the step between the windshield and roof panel.
^ The cross section of the hood seal rubber has been optimized.
^ Hood-to-fender seal is used.
^ A weatherstrip that creates a flush surface from the front fender panel to the rear door outer panel has been provided. Furthermore, a fender seal has been provided on the front fender to close the gap between the front fender and the body.
