Isn't this an old concept, a crime group that tries to hold its meetings in secret, knowing Superman is passively scanning the whole city at all times? A headquarters made of lead would attract his attention so they try to meet in places that already have lead for normal reasons, like beneath certain pipes or factories.
As for sound, he can hear everything but he constantly bombarded by ground traffic, air traffic, construction sounds, voices, radio and satellite transmissions. Trying to pick up one group committing a crime would be like trying to find a needle in a stack of needles.
I can't remember where I read the concept. Early 2000s Lex Luthor: Man of Steel?
Think that DC has shown to us that he can screen out and filter all noses to zero in on particular sound!
