What is audience? Sorry, I'm unfamiliar with some of the Western charts.
It's an approximation of how many times the song has been heard on the radio (the numbers are in millions). The idea is that every time a person hears a song on the radio once, it counts as 1 audience impression. So for example, it's estimated that in total this week, "Here" has been heard about 16.5 million times on US pop radio.
EDIT: Why did I have a feeling that Alexander would beat me to this
