What does NVH stand for and why is it important in automotive design?

NVH stands for Noise, Vibration, and Harshness. Noise refers to audible sounds (engine, wind, road noise), vibration refers to tactile oscillations felt through steering, seats, and pedals, and harshness describes the vehicle's response to impacts like potholes. NVH is crucial for customer comfort, perceived quality, and brand differentiation. Engineers use isolation mounts, damping materials, and structural optimization to minimize NVH.
