It's not the same though. The internal logic of the film shows that a Kryptonian suffers sensory overload when 2 or more super sense activate simultaneously (X-Ray Vision + Super hearing). If he's not focusing on his super hearing (or he focuses on a different spectrum), then loud noises wouldn't hurt him. Moreover, you could even operate under the logic that because his body is indestructible, that his eardrums wouldn't be sensitive to loud noises unlike the human ear. Recoil, yes. But he's not getting harmed so it's pointless. Moreover, Superman could simply fly out of the target range. Also, I have a hard time believing that Batman would resort to destructive methods especially if he is personally insulted by the Metropolis battle. I think it's likely that LexCorp took it than Batman. And it would have to depend on the story logic. Is Lex teaming up with Batman? Is Lex's involvement only the public disdain/attack on Superman? I think it's more likely that LexCorp takes the technology and researches its functions in secret. That would imply that heroes have banded prior to Superman's arrival, which I don't think is possible given how some heroes may have large egos (for instance, Batman telling Superman to literally gtfo of Gotham in the Byrne chapter). That also makes it more difficult to tell the Justice League story, since the origins is based on heroes banding together against a common enemy, or Martian Manhunter unites them against a common enemy (again, depends on which continuities you're familiar with). Also, I don't think it's fair to involve the proto-league if the film is saying that two men are fighting. Luthor is the farthest I'd go for a Batman team-up. This presupposes that Batman knows how Kryptonian biology works and that's simply impossible. Wayne is a smart man, no doubt but that, but he would not know about Kryptonian atmosphere by virtue of the fact that research on Kryptonians are non-existent (that can change for MOS II/BvS, unless Superman had a burial for Zod, in that case, it becomes more difficult to acquire data). Not to mention, the Black Zero sequence took place in space. No one other than Lois Lane knows that Superman cannot handle Kryptonian atmosphere. So I can't really see Batman planning this far without sounding like an ass pull. Snyder can certainly take a side and present that story, but I feel like his love for Superman and the comic-con interview where he basically said Superman wins (interesting enough, Goyer admits that Superman would win in a fight), would seep into the script.
