WARNING: Director Zack Snyder has clarified a certain plot point in Batman v Superman: Dawn of Justice that's been identified by some viewers — but beware. There are some mild spoilers ahead if you haven't seen the film yet.
In the movie, Martha Kent is kidnapped by Lex Luthor as a method of manipulating Superman, and the Man of Steel seems unaware that she's been captured until Luthor fills him in. Presumably, Clark would have an ear attuned to his mother at all times to make sure she's safe, but Snyder told IGN why this isn't so:
“To me, from Metropolis to Smallville is probably just on the edge of his range of hearing. Also the clutter of the city makes it difficult as well. We had a scene that we cut from the movie where he tries to look for her when he finds out that Lex has got her. It was a slightly dark scene that we cut out because it sort of represented this dark side. Because when he was looking for his mom he heard all the cries of all the potential crimes going on in the city.
"I kind of like the idea that he’s taught himself not to look because if he looks it’s just never ending, right? You have to know when, as Superman, when to intervene and when not to. ... You can’t be everywhere at once."
Certainly an interesting take, and at the very least it's a clarification on this point that has caused some discussion among fans.
If you're looking for a scene in which Superman actively listens for crime and seems OK with doing so — and showcases that his super hearing works all the way from space — there's always Superman Returns:
