Road noise generally consists of low-frequency structural noise (such as low-frequency thumping, rumbling and tire cavity resonance noise) and high-frequency airborne noise (like tire pattern noise). Structural noise typically falls below 500 Hz, while high-frequency airborne noise lies above 500 Hz. Different types of road noise require targeted improvement solutions.
Road noise development and tuning is a systematic project calling for coordinated optimization across multiple dimensions including tire matching, body structure, chassis system and acoustic packaging. Future development trends center on deep integration of lightweight materials, active noise reduction technology and intelligent simulation tools, which balances cost, weight and performance to upgrade driving experience for end users.
