Sonic Intimacy asks us who—or what—deserves to have a voice, beyond the human. Arguing that our ears are far too narrowly attuned to our own species, the book explores four different types of voices: the cybernetic, the gendered, the creaturely, and the ecological. Through both a conceptual framework and a series of case studies, Dominic Pettman tracks some of the ways in which these voices intersect and interact. He demonstrates how intimacy is forged through the ear, perhaps even more than through any other sense, mode, or medium. The voice, then, is what creates intimacy, both fleeting and lasting, not only between people, but also between animals, machines, and even natural elements: those presumed not to have a voice in the first place. Taken together, the manifold, material, actual voices of the world, whether primarily natural or technological, are a complex cacophony that is desperately trying to tell us something about the rapidly failing health of the planet and its inhabitants. As Pettman cautions, we would do well to listen.
