Hearing in space (please check my science)

[Aaron Chandler]

I'm writing my own science fiction IP. And so far I'm having a blast with the world building. Or should I say worlds building? Anyway, I'm putting a lot of thought into how people would keep themselves alive in space. I'd like some input on one of my "future tech thingambobs." 

People can't hear anything in the vacuum of space because soundwaves need matter to travel. But hearing is actually pretty important for a number of reasons. So it only makes sense that people would find a solution of some kind. Mine is as simple as substituting on wave for another. In this case radiation waves caused by objects moving against each other. Like someone stomping along the surface of planetoid, the opening of a hatch, the explosion of a rover, or the opening of a pouch. To my understanding all of these events would release a small burst of radio activity. So if someone's head gear had something the would detect those burst and translate them to sound, they could effectively hear in space. 

Are there any smartypants types around who wouldn't mind checking my science and giving me some useful feed back?

I'm unaware of any radiowaves that would be generated by any of these, though I don't know if they wouldn't.

Most matter is naturally radioactive to some extent, so depending on how advanced this civilization is you could sense that.

Well, the way phones work is by transferring data via light waves and translating them into sound. So carrying information like that is pretty feasible, I'd say. But what you're suggesting is that you can simply detect light wave fluctuation when stuff happens, right?

Similar. Some manner of detectable emission. I would imagine there are plenty of things the device wouldn't be able to detect. Moreover, the system would have to filter out stellar and other "laud" forms of radiation.

Movement and whatnot would generate Infrared Rays as far as I know. Nearby stars do the same, but at a distance you're mostly gonna get X-rays and maybe a bit of Gamma if you're really unlucky. As long as it's detecting things with a lower frequency than Microwaves then you should be fine.
