First off Chandra isn't on "earth" it is in space...having been deposited there on a shuttle flight and then repositioned to a much higher orbit/trajectory. Second "sound" is created by a vibration traveling through a substance, not needfully air. This vibration is called a "sound wave". "Sound waves" (sic) can be in inaudible as well as audible ranges. So if a tree falls in the forest and there is no one to hear it there is no sound per-se but "sound waves" are created........therefore simply because we have never heard a "Black Hole" before simply means that we haven't heard it and 'not' that there have been no sound waves created by the danged thingee. :-) Third The context of "hearing" used is in the x-ray range and not the audible spectrum....aka deteced by x-ray and not "heard by ears.
