[The Flash/Speedsters] Is there a minimum distance I can shoot someone where a speedster couldn't save them?

Basically, can speedsters hear bullets "faster than sound" or are they limited to reactions based on their own senses?

If I shoot a supersonic bullet at someone, The Flash hears the bullet and runs across town to stop it. I know Flash has such speed feats he basically teleports there, but he still needs to hear the bullet first, right? So, there would be a distance at which the bullet reaches the target before the sound waves reach Flash's ears.

I'm looking for any examples of speedsters reacting faster than the information could reach them. Given all the speedforce shenanigans that have happened I didn't want to dismiss it as not possible, but I couldn't think of a concrete example.

Depends on how fast the speedster is, but generally if you're able to pull the trigger with the gun pressed against their head you can outspeed most A-Class speedsters. But there'll always be a couple exceptions like the Flash with his "traveling half the distance of the universe faster than instant teleportation" bull shit.
