NVH Noise, Vibration and Harshness NVH 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. Noise: Noise is defined as any unpleasant or unexpected sound created by a vibrating object. Vibration: Vibration is defined as any objectionable repetitive motion of an

Audible Range of Sound – Sounds that are in the range of 20 to 20,000 Hertz (Hz). Amplitude – The vertical measurement between the top and bottom of a wave. Also see magnitude. Beat – An NVH concern produced by two sounds that is most noticeable when the frequency difference is 1 to 6 Hz. Bead Seating – The process
