Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
NVH engineering (noise, vibration, and harshness): NVH involves customer feedback (both tactile [felt] and audible [heard]) concerning a vehicle. While sound can be interpreted as a rattle, squeal, or hot, a tactile response can be seat vibration or a buzz in the steering wheel. This feedback is generated by components either rubbing, vibrating ...
Electronic noise control: Electronics, sensors, and computers are also employed to cancel noise by using phase cancellation which matches the sound amplitude with a wave of the opposite polarity. This method employs the use of an active sound generating device, such as a loudspeaker to counteract ambient noise in an area.
Types of components that can be studied through multibody simulation range from electronic control systems to noise, vibration and harshness. [7] Complex models such as engines are composed of individually designed components, e.g. pistons and crankshafts. [8] The MBS process often can be divided in 5 main activities.
Since "Noise, vibration, and harshness" is not a company, place or person, but rather a way of describing noises etc in vehicles, the title should be converted to lower-case. OSX (talk • contributions) 06:48, 20 October 2008 (UTC)

Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.
