ABSTRACT:
The condition of a gas turbine is monitored by locating a microphone in the air inlet and listening to or recording the sounds detected during certain periods of the machine operating cycle. By proper selection and control of those periods, the operator is enabled to detect rubs or other problems but is not exposed to undesirable noise levels.
