I wouldn't expect human ears to be able to pick it up, because human ears would have far more serious problems just being exposed to the vacuum of space. But if it's possible to make sensors that can detect this sound, and devices that can generate it, and communication between the two would be accurate and really this fast, well, that would certainly be interesting.
Not sure if it would actually be useful, because I'm sure radio waves would be much more practical, but sound in space is a fascinating idea.
Given the impedance mismatch[0], even the parts of the solar system outside Kármán lines where the interplanetary medium can support pressure levels equivalent to normal speaking (including low Earth orbit), I'm told human ears can't respond to that pressure change properly.
Sensors can be built to pick it up, but that may not be in scope for your question as we can also do that for acoustic waves in the CMB.
