I feel like if your hearing was good enough to hear people's heartbeats you would have a much better understanding of their mood, emotions etc. I imagine when people say that animals can "smell fear" or similar, this is actually what's going on.
Likewise you'd probably also hear everyone's digestion so that might be a bit gross.
