Noise, vibration, and harshness (NVH) analysis constitutes a vital aspect of vehicle and machinery design, intending to reduce undesired noise, vibration, and harshness to improve user comfort and satisfaction. We analyse components such as engines, powertrains, and car bodies, and integrate NVH considerations throughout the design process. We utilize various methods, such as acoustic, structural, and aerodynamic simulations, to comprehend and address NVH concerns.
