Sound Proofing / Insulation: Description and Operation
Low Vibration and Low Noise Body
1. General
^ Effective application of vibration damping and noise suppressant materials reduces engine noise and road noise.
^ The front floor panel is curved and the rigidity of the panel has been ensured, restricting vibration.
^ A reinforcement is used on the front of the tunnel section, restricting the movement of the body frame and reducing vibration.
^ Two bulkheads are used on the inner side in the rocker panel, restricting the movement of the body frame and reducing vibration.
