Wind Noise Development and Tuning
Wind noise is generated by the interaction between airflow and vehicle body structure during driving. Generally, when the vehicle speed exceeds 80 kph, wind noise becomes the dominant noise source inside the cabin. The development and tuning of automotive wind noise constitute a vital part of full-vehicle NVH performance engineering, requiring cross-disciplinary collaboration among aerodynamics, acoustics, material science and other fields. The core goal is to reduce perceived wind noise and improve riding experience through optimized design of body structure, vehicle sealing systems and acoustic packages.
Wind Noise Development and Tuning
Product Overview

Landtop Technology owns a self-contained independent wind noise development system. Based on wind noise generation mechanisms, we set development targets and control measures tier by tier at full-vehicle, system and component levels. By integrating CFD simulation, wind tunnel testing and real vehicle tuning, all development targets at each tier can be fulfilled.


Landtop Technology has provided abundant wind noise improvement solutions for many mainstream vehicle manufacturers, delivering excellent wind noise NVH performance for multiple best-selling vehicle models.
