Sound and vibration are a natural by-product of modern society’s manufacturing, transportation and communication activities. NVH optimization for a full vehicle is a major trade-off criteria compared to cost, emission and durability. DEP’s NVH team can support you to quantify NVH by reducing it at the source, isolating it from the product’s structure and controlling it to the permissible level. With an extensive range of industry leading tools and techniques, our engineers can design automotive vehicles to absorb as much noise and vibration as possible before it enters the cabin. We aim to provide:

  • Increased comfort and quietness
  • Necessary competitive edge
  • Performance enhancement affected due to structural NVH
  • Extended Durability and optimized solutions
