Revolutionary vibroacoustic analysis reveals how engine excitation and road roughness at low speeds cause structural elements like doors, roofs and windshields to resonate at natural frequencies. These resonances amplify low-frequency noise (boom effect) inside the cabin, affecting passenger comfort.

This study employs an acoustic dynamometer in a semi-anechoic environment with rough road shells and a 3D laser vibrometer integrated with a seven-axis Kuka robot embedded with Robovip software for precise vibration measurements.

Real-time data acquisition and FEM simulations correlate experimental results with predictive modeling, optimizing noise control strategies and enhancing vehicle design. Find out more at KFB's booth.
