This paper discusses the methods that detect the leakage of the pneumatic circle of the bus door, shedding light on a new approach to determining the leakage. Difficulties that face the leakage detection process are related to the complicated circle, and the available methods for detection. Applying different methods of non-destructive testing and distinguishing between them through acoustic emission. The study concentrates on the analysis, investigation, performance, and the new applications of the pneumatic circle of bus door. An artificial leak is made in the circle which is controlled manually to determine the quantity and location. The necessary parameters for comparison have been selected after analysing the signals that were obtained from the tests. Root mean square (RMS) of acoustic emission signal, frequency spectrum and time describe the different responses and changing in the signal with and without leakage related with the behaviour of the signal during open and close the door. Due to more stringent safety requirements, buses used by public transport companies and private operators have had safety controls fitted to protect their passengers and to reduce the hazard of accidents in the traffic.
