A Rattle Signal Denoising and Enhancing Method Based on Wavelet Packet Decomposition and Mathematical Morphology Filter for Vehicle
Buzz, squeak and rattle (BSR) noise has become apparent in vehicles due to the significant reductions in engine noise and road noise.The BSR often occurs in driving condition with many interference signals.Thus, the automatic BSR detection remains a challenge for vehicle engineers.In this paper, a rattle signal denoising and enhancing method is pro
