AR Based Vehicle Acoustic Signal Power Spectrum Analysis
In this paper, the vehicle acoustic signal is acquired in real-time and its AR power spectrum is derived through the integration of several groups of parameters. By using acoustic samples of moving vehicles, the AR spectrum is validated and shows that the vehicle acoustic signals spectrum is mainly in the low frequency range, with its primary spectrum stretching from 180Hz to 430Hz.
