"Chion's work is refreshing in many ways.... It is clear that Chion lives his topic deeply, and has not simply "researched" it. Alongside the extended theorisation, the book teems with thought-provoking observations, like the best of Jean Baudrillard (who could always be appreciated for his vignettes if not for his theories) or Roland Barthes. How good it is to find that someone else has asked himself why being subjected to one side of a conversation on a mobile phone is even more frustrating than overhearing a two-way conversation in person - and Chion has an answer."–David Revill "Times Higher Education"
