Sounding the Indian Ocean is the first volume to integrate the fields of ethnomusicology and Indian Ocean studies. Drawing on historical and ethnographic approaches, the book explores what music reveals about mobility, diaspora, colonialism, religious networks, media, and performance. Collectively, the chapters examine different ways the Indian Ocean might be “heard” outside of a reliance on colonial archives and elite textual traditions, integrating methods from music and sound studies into the history and anthropology of the region. Challenging the area studies paradigm—which has long cast Africa, the Middle East, and Asia as separate musical cultures—the book shows how music both forms and crosses boundaries in the Indian Ocean world.

"Providing numerous case studies ranging across the Indian Ocean--across disparate time periods and historical and ethnographic approaches--Sounding the Indian Ocean: Musical Circulations in the Afro-Asiatic Seascape brings together the disciplines of Indian Ocean and music studies. As glimpsed above in the Sufi and Catholic networks connecting South and Southeast Asia, the chapters in this volume explore how music helps materialize networks of connection across the Indian Ocean Region (IOR) and in several of its distinct locales. Our focus is not simply the well-worn tropes of Indian Ocean cosmopolitanism, however, nor a definition of the IOR as a site for the harmonious mixing of populations (though some of our chapters do one or both of these). Rather, we show how music contributes to placemaking in distinct 'Indian Ocean worlds' (Srinivas et al. 2020). Instead of defining music's value in its ability to provide either narratives of identity formation or the celebration of mixture, Sounding the Indian Ocean explores the role music plays in both boundary-formation and boundary-crossing in Indian Ocean contexts, past and present"--

Sounding Islam provides a provocative account of the sonic dimensions of religion, combining perspectives from the anthropology of media and sound studies, as well as drawing on neo-phenomenological approaches to atmospheres. Using long-term ethnographic research on devotional Islam in Mauritius, Patrick Eisenlohr explores how the voice, as a site of divine manifestation, becomes refracted in media practices that have become integral parts of religious traditions. At the core of Eisenlohr’s concern is the interplay of voice, media, affect, and listeners’ religious experiences. Sounding Islam sheds new light on a key dimension of religion, the sonic incitement of sensations that are often difficult to translate into language.

Initial results of a continuing study to analyze and summarize the acoustically significant characteristics of the vertical sound-speed structure in the Indian Ocean are presented for purposes of acoustic model inputs and future exercise planning in the region. Data displays cover the western Indian Ocean west of 75 degrees E and north of 20 degrees S. Hydrocast data with computed sound speeds at standard depths provide the basic information to define areas of the Indian Ocean that are reasonably homogeneous with regard to sound-speed properties and can be summarized by a single profile for each season. Seasonal data presentations of bottom conjugate depth (the shallow conjugate of the bottom sound speed) and depth excess (water depth below the deep conjugate of the near-surface sound-speed maximum) indicate the primarily bottom-limited situation in the western Indian Ocean and identify the restricted areas of the Somali Basin with convergence-zone propagation potential. The upper-layer characteristics of layer depth, in-layer gradient, and below-layer gradient are displayed seasonally in contour format based on sound-speed-converted BT and XBT temperature data. Emphasis is placed on the significant effects of the seasonal monsoons, and in particular the strong SW Monsoon, on the near-surface structure. Results based on the two data sources are presented separately and some comparisons are made.

Sound Images of the Ocean is the first comprehensive overview of acoustic imaging applications in the various fields of marine research, utilization, surveillance, and protection. The book employs 400 sound images of the sea floor and of processes in the sea volume, contributed by more than 120 marine experts from 22 nations.
