Sound Proofing / Insulation: Description and Operation
Low Vibration and Low Noise Body1. General
An effective application of vibration damping and noise suppressant materials reduces engine and road noise.
2. Sound Absorbing and Vibration Damping Materials
^ Foamed urethane sponge and foamed seal material are applied onto the roof panel and pillars to reduce wind and road noise.
^ Asphalt sheet is used to reduce road noise.
^ Adoption of the dash panel silencer and hood silencer have reduced engine and road noise and improved the quietness in the compartment.
^ Felt is used effectively on the flower and roof (only for without moon roof) to ensure a quiet interior.
3. Reducing Wind Noise
^ The area in which the top of the front windshield and the roof join has been shaped linearly to reduce wind noise.
^ The cowl louver and wiper arms have been optimally located to reduce wind noise from the engine compartment to the front windshield.
4. Weather Strip
^ Two layers of inner weather strips and door belt mouldings are used on the front and rear doors to improve sound insulation performance.
^ A door opening trim weather strip has been placed along the entire opening of the front and rear doors to ensure the stable sound isolation performance of the vehicle interior.
