The red marker is our best guess at the source; the blue dots are where people were. This combines two independent clues: the 3 directions people pointed, and how loud it was where each person stood (a boom is loudest nearest its source). The marker sits where those two agree - which is why it's more trustworthy than either alone. Adding more directions or loudness reports sharpens it.
