From 1940 to 1990, new machines and devices radically changed listening to music. Small and large single records, new kinds of jukeboxes and loudspeaker systems not only made it possible to playback music in a different way, they also evidence a fundamental transformation of music and listening itself. Taking the media and machines through which listening took place during this period, Listening Devices develops a new history of listening.Although these devices were (and often still are) easily accessible, up to now we have no concept of them. To address this gap, this volume proposes the term “listening device.” In conjunction with this concept, the book develops an original and fruitful method for exploring listening as a historical subject that has been increasingly organized in relation to technology. Case studies of four listening devices are the points of departure for the analysis, which leads the reader down unfamiliar paths, traversing the popular sound worlds of 1950s rock 'n' roll culture and the disco and club culture of the 1970s and 1980s. Despite all the characteristics specific to the different listening devices, they can nevertheless be compared because of the fundamental similarities they share: they model and manage listening, they actively mediate between the listener and the music heard, and it is this mediation that brings both listener and the music listened to into being. Ultimately, however, the intention is that the listening devices themselves should not be heard so that the music they playback can be heard. Thus, they take the history of listening to its very limits and confront it with its “other”-a history of non-listening. The book proposes “listening device” as a key concept for sound studies, popular music studies, musicology, and media studies. With this conceptual key, a new, productive understanding of past music and sound cultures of the pre-digital era can be unlocked, and, not least, of the listening culture of the digital present.

Your voice as biometric data, and how marketers are using it to manipulate you Only three decades ago, it was inconceivable that virtually entire populations would be carrying around wireless phones wherever they went, or that peoples’ exact locations could be tracked by those devices. We now take both for granted. Even just a decade ago the idea that individuals’ voices could be used to identify and draw inferences about them as they shopped or interacted with retailers seemed like something out of a science fiction novel. Yet a new business sector is emerging to do exactly that. The first in-depth examination of the voice intelligence industry, The Voice Catchers exposes how artificial intelligence is enabling personalized marketing and discrimination through voice analysis. Amazon and Google have numerous patents pertaining to voice profiling, and even now their smart speakers are extracting and using voice prints for identification and more. Customer service centers are already approaching every caller based on what they conclude a caller’s voice reveals about that person’s emotions, sentiments, and personality, often in real time. In fact, many scientists believe that a person’s weight, height, age, and race, not to mention any illnesses they may have, can also be identified from the sound of that individual’s voice. Ultimately not only marketers, but also politicians and governments, may use voice profiling to infer personal characteristics for selfish interests and not for the benefit of a citizen or of society as a whole. Leading communications scholar Joseph Turow places the voice intelligence industry in historical perspective, explores its contemporary developments, and offers a clarion call for regulating this rising surveillance regime.
