One witness said they "had a boom box" which was "really, really loud at one stage."
Another said the man had been shouting from his balcony.
He went down to ask again but police say he was surrounded and bashed, ending up in hospital with facial injuries.
"He believes he was lying there for an hour but we're to investigate that properly," Inspector Vanessa Robinson from NSW Police said.
