Reducing NVH in modern automobiles is a multi-faceted challenge that encompasses various design considerations. To effectively minimize noise, vibration, and harshness, engineers focus on aspects such as:

  • Material selection for sound insulation and vibration damping
  • Design of engine mounts and suspension components to reduce transmitted vibrations
  • Aerodynamic design to reduce wind noise at high speeds
  • Use of active noise cancellation technologies
  • Design and placement of exhaust components to minimize sound levels

Examples might include the use of composite materials for panels that provide both lightness and damping qualities, or the strategic placement of sound-deadening foam in the vehicle's body cavities.

For more comprehensive insights into NVH reduction techniques, the SAE (Society of Automotive Engineers) provides extensive resources and studies on this topic. SAE Technical Papers

This is an essential area of focus, especially with the rise of electric vehicles where road and wind noise become more noticeable.

Do these NVH considerations vary significantly between ICE and electric vehicles?

I've noticed that luxury car brands tend to invest more in NVH reduction. Is it cost-prohibitive for economy models?
