What does NVH mean in cars?
2 Answers
NVH in cars stands for Noise, Vibration, and Harshness. Here are detailed introductions about NVH: 1. Function: It is a comprehensive indicator to measure the manufacturing quality of automobiles, providing the most subjective and superficial experience for car users. NVH issues in vehicles are one of the concerns for major automobile manufacturers and parts companies in the international automotive industry. 2. Problem classification: NVH issues exist everywhere. According to their sources, they can be divided into three main categories: engine NVH, body NVH, and chassis NVH, which can be further subdivided into aerodynamic NVH, air conditioning system NVH, road driving NVH, braking system NVH, etc.
NVH in cars, I've driven quite a few vehicles and found that it actually stands for Noise, Vibration, and Harshness. Simply put, it's about how the internal and external movements affect your driving experience. Noise refers to sounds like engine noise and wind noise; vibration is the shaking of the steering wheel or seats; and harshness refers to the stiff, bumpy feeling when encountering uneven road surfaces. For example, if the NVH is poor on the highway, your ears might buzz, your hands might go numb from the vibrations, and you'll feel fatigued after driving for a long time. Nowadays, many new cars are improving this by using double-glazed windows or optimizing the chassis to make the interior quieter. I recommend testing the car on suburban roads with varying speeds to see how well the noise is controlled. Also, don't neglect regular maintenance, as worn tires or old suspension can worsen vibrations.
