Sound Media considers how music recording, radio broadcasting and muzak influence people's daily lives and introduces the many and varied creative techniques that have developed in music and journalism throughout the twentieth century. Lars Nyre starts with the contemporary cultures of sound media, and works back to the archaic soundscapes of the 1870s.

The first part of the book devotes five chapters to contemporary digital media, and presents the internet, the personal computer, digital radio (news and talk) and various types of loudspeaker media (muzak, DJ-ing, clubbing and PA systems). The second part examines the historical accumulation of techniques and sounds in sound media, and presents multitrack music in the 1960s, the golden age of radio in the 1950s and back to the 1930s, microphone recording of music in the 1930s, the experimental phase of wireless radio in the 1910s and 1900s, and the invention of the gramophone and phonograph in the late nineteenth century.

Sound Media includes a soundtrack CD with thirty-six examples from broadcasting and music recording in Europe and the USA, from Edith Piaf to Sarah Cox, and is richly illustrated with figures, timelines and technical drawings.
