The sound of consumption: The electromagnetic soundwalk as anti-method

Abstract This article proposes the electromagnetic soundwalk as an anti-method for consumer research, a compositional practice that listens to the infrastructural residue of market environments without aiming to interpret, represent or explain. Using a handheld electromagnetic detector, the walk transposes imperceptible emissions into audible frequencies, revealing the operational murmur of retail systems. These include devices such as wireless payment systems, contactless terminals, touch-screen tablets and digital signage, technologies that organise and condition consumer experience, but do so silently, beneath the threshold of ordinary perception. These electromagnetic emissions trace the infrastructures that shape and facilitate consumption yet remain formally outside marketing discourse. The soundwalk stages a form of methodological estrangement, where listening becomes a way of staying with systems that persist without expressive form. While rooted in soundwalking traditions, the project diverges from immersion or participation. Positioned within the sonic turn in consumer research, the paper reframes sound as residue, an ambient trace of logistical systems. For marketing, this is a speculative proposition. For sound studies, it is an example of compositional listening used to breach an adjacent field. What results is not a soundwalk for its own sake, but an acoustic method for hearing how consumer systems continue, quietly and without reward. The first section of the paper adopts a speculative and affective tone, free of citation, to evoke the experiential register of the method. Subsequent sections develop the theoretical and methodological foundations in a more conventional academic voice.
