Abstract
: Vehicles generate dissimilar sound patterns under different working environments. These generated sound patterns signify the condition of the engines, which in turn is used for diagnosing various faults. In this paper, the sound signals produced by motorcycles are analyzed to locate various faults. The important attributes are extracted from the generated sound signals based on time, frequency and wavelet domains which clearly describe the statistical behavior of the signals. Further, various types of faults are classi fi ed using the Extreme Learning Machine (ELM) classi fi er from the extracted features. More-over, the improved classi fi cation performance is obtained by the combination of feature sets in different domains. The simulation results clearly demonstrate that the proposed hybrid feature set together with the ELM classi fi er gives more promising results with higher classi fi cation accuracy when compared with the other conventional methods.
