NVH Technology
Acoustic Material
Isolating Airborne Noise
Large-area absorbers and sound barriers combined with cavity baffles form a powerful sound barrier and absorption shield, ensuring quietness whether parked or driving.
Acoustic Material
The area of sound-absorbing materials exceeds the industry standard by 20%, while the number of cavity barriers surpasses peers by 35%. High-density EVA and PU materials form a heavy-duty sound barrier, isolating airborne noise in all conditions, ensuring quietness whether parked or driving.
Vibration Isolation, Mode Separation and Vibration Absorption
Isolating Structural-borne Noise
Through three major technologies: vibration isolation, mode separation, and vibration absorption, it solves the final 1-2 decibels of low-frequency structural-borne noise problems. The sound insulation performance of our vehicles are comparable to top luxury vehicles across all vehicle models.
Vibration Isolation, Mode Separation and Vibration Absorption
42 chassis bushings isolate vibration energy. Mass blocks are used for targeted frequency avoidance, dissipating noise energy and solving the final 1 decibel problem.
