Sound Proofing / Insulation: Description and Operation
Low Vibration and Low Noise Body1. General
Effective application of vibration damping and noise suppresant materials reduces engine and road noise.
2. Sound Absorbing and Vibration Damping Materials
^ Asphalt sheets are optimally place to reduce engine and road noise for quieter vehicle operation.
^ Resin felt pads that are effective in absorbing sounds are optimally placed to reduce road noise to ensure quieter vehicle operation.
^ The layout and the cross section of the roof reinforcements have been optimized in order to generate vibrations at opposite phases, instead of the previous same-phase vibrations. As a result, the vibration on the roof panel has been significantly reduced, thus ensuring quieter operation.
^ A dynamic damper has been provided on the back door, which is susceptible to the influences of the booming sound. Thus, the booming sound that occurs during idling or is transmitted from the road has been reduced.
