Sound files to accompany thesis. The project sought to explore the significance of sound to the relationships and wellbeing of those living and working in a local men's prison. The research design was underpinned by a particular understanding of sound - as aural packages of meaning-making. In this sense sound was used to mean aural aspects of social experience, an understanding which was incorporated in to more traditional approaches to ethnography; an aural ethnography. Over seven months was spent in a local men's prison, conducting ethnography and ethnographically-informed interviews. Using sound as a theoretical framework to explore prison life revealed the ways in which the ontological security offered by the rhythms and routines of a predictably structured day were central to processes of order maintenance, and to strategies of survival in the prison environment.
