How Superman super hearing work ?

Superman can hear someone from another planet, and hear a bullet and be there before it hit someone...but the sound it self have only sound speed. How Superman can hear that in the instant that happens ?

Anyone ever make some explanation or he just can do that...?

the speed of sound is about 767 mph.. the average speed of a 9mm bullet is about 680 mph.. and superman is faster than a speeding bullet, so..

I think OP is asking about how he can hear things from across the planet as they are happening, so how does he hear it when logically the sound would not have reach him yet.

This is not a flippant answer:

Its one of those things. Like how Sunspot can punch something using super strength without crushing his hand, even though he's not invulnerable.

Yes, that is my question. He can even hear people from other planets.

Yep. He even heard GL calling him for help from another solar system. It may've even been another galaxy but I can't remember because it's been so long since I read that story... It doesn't really make sense though considering sound isn't supposed to travel in space. But, it's not like there isn't already a ton of stuff in comics anyway that doesn't make any sense. Things like Zoom punching Superman without breaking every bone in his hand, for example. LOL.

So yeah, basically what Riv said. 😛

Superman can hear EM and gravitational radiation, that's how sensitive his ears are. His speech mechanisms are similarly impressive, with the ability to form EM and gravitational radiation into words in the vacuum of space. This way, not only can others hear him, but others can actually talk to each other in space even when the Man o' Steel isn't present.

Yeah, thats worse than "its one of those things". 😂
