Understanding Noise, Vibration, and Harshness

What does NVH stand for? Noise, Vibration, and Harshness (NVH) refers to the study and control of unwanted sound and movement in mechanical systems. It is a critical factor in engineering and product development, impacting everything from user comfort to system longevity. Noise pertains to unwanted sound emissions, vibration refers to mechanical oscillations, and harshness relates to the perceived roughness or impact of these factors on a user or system. Addressing these challenges is essential for improving product quality, efficiency, and user satisfaction.

In modern engineering, reducing unwanted sound and movement plays a crucial role in ensuring optimal performance, durability, and user comfort across various industries. At Protec Group Limited, we specialize in delivering tailored solutions that address the unique challenges faced by automotive, rail, and aerospace applications.
