Device for detecting the defect of vehicle using the analysis of noise patterns

PURPOSE: A device for detecting defect of a vehicle using analysis of noise patterns is provided to detect a trouble of a predetermined part by measuring noises of each part of the vehicle. CONSTITUTION: A device for detecting the defect of a vehicle using the analysis of noise patterns includes a microphone part(20), a noise analysis part(30), a data storing part(50), a calculation control part(40), a display part(70), and a key inputting part(60). The microphone part(20) includes a plurality of microphones in order to detect noises of each part and output the noises as electrical signals. The noise analysis part(30) converts noises of each part of the vehicle into frequency by analyzing the noises of each part using the electrical signals inputted from the microphones(20). The calculation control part(40) compares the frequency with normal/abnormal pattern data stored in the data storing part(50).
