NVH Testing
NVH Testing (Noise, Vibration, and Harshness Testing) is a key quality control process in the automotive industry. It's like giving a car a thorough check-up to make sure it runs smoothly and quietly. Specialists use special equipment to measure and analyze unwanted sounds, vibrations, and rough movements in vehicles. This is important because customers expect their cars to be comfortable and quiet. Think of it as making sure a car doesn't rattle, hum too loudly, or shake uncomfortably when driven.
