Abstract

 Noise, Vibration, and Harshness (NVH) are critical parameters in vehicle engineering that impact driving comfort, safety, and performance. This paper explores the major sources of NVH, focusing on road irregularities, wheels, and powertrain components, including the internal combustion engine (ICE) and transmission. Various mitigation strategies are also discussed to improve vehicle NVH characteristics. Understanding NVH is essential for both manufacturers and consumers, as it influences vehicle durability, passenger experience, and market competitiveness.
