Noise, vibration and harshness, also known as noise and vibration, abbreviated to NVH and N&V respectively, is the name given to the field of measuring and modifying the noise and vibration characteristics of vehicles, particularly cars and trucks. Harshness is somewhat of an historical misnomer. Noise and vibration can be measured, but harshness is a more subjective assessment. There is a psychoacoustic measurement called harshness but it does not correlate very well with many harshness issues. Interior NVH is the noise and vibration experienced by the occupants of the vehicle cabin, while exterior NVH is largely concerned with the noise radiated by the vehicle, and includes drive-by noise. The noise being generated by fluid pressure fluctuation and passage through the air is called airborne noise. The noise radiated from a structure’s surface that is vibrating is called structure-borne noise. Noise is used here to describe audible sound, with particular attention paid to the frequency range from 30 to 4000 Hz. Vibration is used to describe tactile vibration, with particular attention paid to the frequency range from 30 to 200 Hz
