Abstract
An abnormal noise reproduction device and an abnormal noise reproduction method thereof are provided in the disclosure. The abnormal noise reproduction device includes at least one measuring device, an analysis device, and a vibration device. The at least one measuring device includes a contact microphone and an accelerometer. The contact microphone is disposed on the abnormal noise generating part of a vehicle, senses vibration sound of the abnormal noise generating part, and generates a vibration sound signal. An acceleration signal is generated by synchronously sensing acceleration of the contact microphone over a time sequence through the accelerometer. The analysis device determines when the abnormal noise generating part produces abnormal noise according to the vibration sound signal. The vibration device applies vibration to the vehicle and reproduces the acceleration signal corresponding to the abnormal noise.
