Noup, it all melts together into one indistinguishable noise. Sometimes it's better, sometimes it's worse.

When a person who I've known for longer time is speaking loudly and clearly towards me and I'm ready to listen, then i can mostly understand what they're saying, of course if the environment is somewhat normal.

But if it's a new person, with a bad speaking mannerisms, that's already enough to make whatever they're saying completely incomprehensible, even in a quiet environment. Add in some noise and there's even no point to try to understand them.
