I remember listening to audiobooks as a child and there were years where I wouldn't sleep unless I had a tape playing in the background. To a child, silence can be pretty ominous and I suppose there is something comforting in having 'someone else' in the room with you, narrating a story as you fall asleep. Even now, when all I seem to crave is silence, there is still something comforting in putting on a pair of headphones and escaping into a world led by the voice of another.
