The Science of Noise, Vibration, & Harshness Control in Electric Vehicles

March 17, 2023

In today's rapidly evolving automotive landscape, electric vehicles (EVs) are experiencing increased adoption and wider public acceptance. This growing interest in EVs has necessitated a deeper understanding of the science behind acoustics, not only to enhance comfort but also to develop effective noise control solutions tailored for this new breed of automobiles. One crucial aspect of sound perception is the frequency of sound waves, with the human ear exhibiting heightened sensitivity to higher frequency sounds. Consequently, developers of noise, vibration, and harshness (NVH) solutions must keep this increased perception of higher frequency noises in mind when working with electric vehicles to create an enjoyable driving experience. In this comprehensive article, we will delve into:


  • A comparative analysis of various vehicle types and their distinct acoustic characteristics
  • The origin and impact of Noise, Vibration, & Harshness in vehicles, and
  • An exploration of innovative NVH control measures for mitigating undesirable frequencies in electric vehicles.
