Why do you think Church chose to essay this particular event through the lens of sound?

The idea of sound plays a pivotal role in Steven Church’s “Seven Fathoms Down.” Why do you think Church chose to essay this particular event through the lens of sound? What sorts of tangents or “corkboard strings” does he follow in order to get to the bottom of things that ultimately influence the “meditative subject” of his essay? In fact, what is this essay really even about? This is a complex piece, and I want us to take our time with our thoughts. If you have something to say about it that isn’t related to the above questions, then, by all means, talk about that instead.
