[DC Comics] How is Batman able to conceal himself from Superman's senses?

In various comics, Batman is somehow able to hide from Superman. He's a master of stealth, sure, but how can he hide from someone with such extreme senses that he can distinguish people's heartbeats, hear in space, see the heat left behind by footprints? And that's just a few examples of his abilities. Is Batman using some sort of magic to conceal himself?

I can't remember the comic run, i'm afraid, but there was one where Batman sneaks up on Superman. When Superman confirms he genuinely hadn't notices Bruce and wasn't just playing along, Batman's response was "good, the device works".  


So yes, he's using nebulous super-tech to keep himself hidden.
