As we converse with a partner, there is space between us created by the sound of our voices and the proximity of our bodies. The sound of the conversation can radiate out of the intended intimate space and be heard by others not necessarily included in the conversation. … Our global attention is engaging with numerous overlapping dimensions created by sounds. At the same time we may be imagining what to say next. We then feel the dimension of imagination or memory.

Pauline Oliveros, Deep Listening, loc. 208
