摘要： An abnormal noise correction verification apparatus is provided that can easily verify the effectiveness a corrective action with respect to an abnormal noise being generated. The apparatus has at least one vibration sensor, which detect vibrations of the vehicle. The apparatus extracts a signal in a specific frequency band for the vibrations detected from the vibration sensor. The apparatus stores a pre-corrective action signal extracted from the vibration sensor, which is from before eliminating a cause of abnormal noise, and a post-corrective action signal extracted from the vibration sensor, which is from after eliminating the cause of abnormal noise. Both pre-corrective action signal and the post-corrective action signal were detected under identical travel conditions by the vibration sensor. The apparatus then synchronizes and separately outputs the pre-corrective action signal and the post-corrective action signal for comparison.
