I once heard an audio tape compiled from data downloads from a high rate accelerometer on the Olympus satellite, from which one could hear thruster firings, valve switching and reaction wheel operation.
Have astronauts reported hearing audible creaking sounds from any extended or docked structures? Its easy to imagine that the docking adaptors would be solid but that extremities such as antennas and solar arrays might transmit vibrations through the structure as their temperature changed through each orbit.
I'm less interested in the noises made by cyclic mechanical machinery such as fans.
