Noise, Vibration and Harshness (NVH) Engineering

Noise, vibration, and harshness (NVH) is the study and modification of the noise and vibration characteristics of automobiles. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via personal evaluations, or with analytical tools that can provide results reflecting human subjective impressions. Interior NVH deals with noise and vibration experienced by the occupants of the cabin, while exterior NVH is largely concerned with the noise radiated by the vehicle, and include drive-by noise testing. Several factors influence the overall NVH rating of a car like Engine and powertrain NVH, Transient NVH Phenomena, Aero-Acoustic Noise, Experimental NVH analysis method, Advanced NVH simulations, Pedestrian warning sound by Electric Vehicles, NVH of light-weight vehicles etc.
