Zusammenfassung:	A method of detecting at least one engine condition of a gas turbine engine (10) using a microphone (22) disposed outside a region of the gas turbine engine (10) to be monitored. The method includes receiving (44) a signal produced by the microphone (22) in response to audible frequencies, analyzing (46) the signal to determine at least one signal characteristic representative of the engine condition, and detecting (48) the engine condition based on the signal produced by the microphone (22).
