The world was dark half the day for much of human history. Communicating in the dark is clearly easier with noise than signing or passing tactile writing around. It's not like we just invented noise for the fun of it, it's just a better medium in most situations.
Well, most of human activity, then and now, is conducted in a lighted environment. Regardless, it is not clear to me how the reasons for vocal/aural communication arising as the dominant mode is at all relevant here.
