There you find a file called "jumpdrive_survey.wav" - that is the looped sound the cloak makes, no matter if it is your own cloak or a foreign one. People have switched that file with either alarms or an engine sound. I for example use this one here: Link
Spazzy uses beeps, other people have my old Apahanta alert sound or modified it themselves. Technically you can even add a mexican monologue or something. It just needs to be a .wav file with that name.
