Low Vibration and Noise Body
LOW VIBRATION AND LOW NOISE BODY1. General
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 sealing material are applied onto the roof panel and pillars to reduce wind and road noise.
^ A large-size dash inner silencer, dash outer silencer, hood silencer and tunnel outer silencer are used to reduce engine and road noise and improve quietness inside the passenger compartment.
^ The fender liner inside the front wheelhouse is covered with a sound absorbing material (Thinsulate) in order to minimize grit, water and road noises.
^ The plastic fender liner, which is made of SBR (Styrene Butadiene Rubber), and PET (Polyethylene Terephthalate) felt is fitted inside the rear wheelhouse in order to minimize grit, water and road noises.
^ In place of the asphalt sheet used on conventional models, a vibration damping foam coating is used on the floor of the new model to reduce road noise.
^ The thickness of the vibration damping foam coating has been optimally adjusted for the individual portions. As a result, a lightweight coating has been realized.
3. Reducing Wind Noise
^ A structure that blocks the airflow is used in a portion of the door weather strip (at the front corner) in order to reduce wind noise (A - A cross section).
^ The air turbulence has been eliminated through the optimization of the shape of the hood seal rubber (B - B cross section) and the use of the hood side seal rubber (C - C cross section).
^ By streamlining the joins between the windshield glass and the roof (D - D cross section) and between the doorframe and the door window glass (E - E cross section), air turbulence has been minimized.
^ A seal rubber is used between the front fender and the side outer to prevent air from blowing through. In addition, a seal rubber is used between the front fender and the front door to eliminate air turbulence. (F - F cross section)
^ Seal rubbers are employed between the front and rear doors to eliminate air turbulence (G - G and H - H cross sections).
