Orientation Identification of Vehicle Accelerating Noise Sources Based on Acoustic Vector Sensor
摘要
Abstract
In order to determine the location of the noise and the type trouble of the vehicle,a method of orientation identification of vehicle accelerating noise sources is proposed,based on acoustic vector sensor.The combustion noise of the vehicle acceleration noise could boil down to a Chirp signal within a certain speed range.Using the acoustic vector sensor combined with traditional omni directional pressure sensor and dipole directional particle velocity sensor simultaneously and colocately measures orthogonal components of particle velocity and pressure at single point in space,and with MUSIC(Multiple Signal Classification)can selectively extract the interested components of the noise sources and present the exact location information.Simulation results verify the performance of the method.关键词
