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.
^ Adoption of the large-size dash panel silencer, the dash outer silencer, the hood silencer, and the engine under cover silencer have reduced the engine and road noise, improving the quietness in the compartment.
^ Asphalt sheet is used to reduce road noise.
^ Felt is used effectively on the floor and roof to ensure a quiet interior.
3. Reducing Wind Noise
^ The area in which the glass and the pillar, and the glass 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
^ 2 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.
