Abstract: Noise, Vibration, and Harshness (NVH) have emerged as crucial parameters in defining the comfort, performance, and perceived quality of modern vehicles. With the rise in consumer expectations and electric vehicle integration, NVH control has become more significant than ever before. This paper explores the sources and classifications of NVH, various technologies and materials used for its reduction, testing methods, and case studies from the automotive industry. A detailed look at active and passive NVH solutions is provided, along with the impact of vehicle electrification. The study concludes that a multidisciplinary approach, combining mechanical design, acoustic engineering, and digital modeling, is essential for achieving superior NVH performance in next-generation vehicles.
Keywords: NVH, acoustic materials, electric vehicles, active noise control, automotive vibration, ride comfort, structural damping
