Sound Proofing / Insulation: Description and Operation
Low Vibration and Low Noise Body1. Sound Absorbing Material
To achieve a quiet cabin, sound absorbing material is optimally allocated across a wide area including the floor carpet, ceiling, inner dash silencer and door trim.
2. Measures to Reduce Wind Noise
The following features are adopted, leading to reduced wind noise.
(a) The configuration of the area around the windshield is optimized.
(b) A window molding with a hidden frame is used to minimize the step between the window and window molding.
(c) The cross section of the hood seal rubber is optimized.
