From Gear Geometry to Sound Branding: A State-of-the-Art Review on Harmonic NVH Engineering in Electric Drivetrains

2026-03-16

Abstract excerpt

Electric vehicles (EVs) have fundamentally changed the noise, vibration, and harshness (NVH) landscape of automotive powertrains. In the absence of masking inter-nal-combustion-engine noise, harmonic components such as gear whine, electric-motor orders, and inverter-related tones become more perceptible and more critical to vehicle re-finement. This review synthesizes the current state of the art in harmonic NVH e...
