Reducing High Frequency Driveshaft Radiated Noise by Polymer Liners

Comprehensive Active Control of Booming Noise Inside a Vehicle Caused by the Engine and the Driveline

“…Another reason is that there has been no study or attempt to generate a reference signal without employing the physical sensor. Thus, most studies have used a passive approach to improving driveline noise [23]- [25]. As a traditional noise, vibration, and harshness (NVH) approach for driveline noise, noise and vibration were improved through the optimal design of the propeller shaft focused on its alignment and balancing [26]- [28].…”
