Unbounded space?

For an Anthropology of Religion class I read an article by Oosterban on how the religious character of a neighbourhood in Rio de Janeiro, Brazil, is determined by the "sonic properties" of the space. He detailed how the funk music of the all night dances (associated with the drug trade) competes for sonic control of the space with the churches that use speakers to project their sermons into the street. This conception of space being divided/categorised by sound made me think of the BBC podcast where one of the interviewees said that to enter unbounded space, all you had to do was close your eyes. It seems that in the context of Oosterban's article, closing your eyes would not allow you to truly leave the bounded space of your immediate surrounding, because you would still hear the soundscape. I agree that vision is often our most privileged sense, but I argue it works in correlation with all our other senses which also work to create our sense of bounded space. "Quiet Hours" enforced in university residences and some neighbourhoods, sent-free zones, phrases like "stay within speaking distance", portable music players and many more aspects of life demonstrate that the idea of "here" is a combination of the information provided to a person's five senses, not just sight.
