What does NVH performance mean?
2 Answers
NVH performance refers to Noise, Vibration, and Harshness. NVH: It is a comprehensive issue that measures the manufacturing quality of automobiles. It directly and superficially affects the perception of car users, and is also one of the concerns for major international automobile manufacturers and component suppliers. NVH issues: They belong to systematic fine-tuning. For example, if a car has excessive cabin noise while driving, and the source is traced to the engine, this noise problem may involve three parts: the engine itself being noisy, poor vibration damping of the engine mounting components, and inadequate sound insulation technology in the front bulkhead and floor of the cabin. This is an interconnected systemic issue.
NVH performance refers to the comfort level experienced during vehicle operation. Every time I embark on a long-distance drive, I pay special attention to interior noise, vibrations, and harsh sounds. Excessive noise resembles a roaring engine, noticeable vibrations may cause the steering wheel to tremble, while harsh sounds like tire squealing on gravel roads can all degrade the driving experience. Effective NVH design ensures quieter and smoother rides—for instance, through high-quality sound insulation materials or softer suspension tuning. This isn’t just about driving pleasure; it also impacts fatigue levels—fewer vibrations mean less exhaustion, allowing better focus during long trips. Many new car models now emphasize this aspect, as it enhances overall luxury beyond just safety. During test drives, evaluating performance across different road conditions reveals strengths and weaknesses. Routine maintenance should include checks on tires and engine mounts to mitigate aging-related issues. Ultimately, NVH performance determines whether daily driving is an enjoyment or an ordeal.
