This studio-based course explores the relationship of urban space, media and sound. Through literature seminars, group activities and individual projects, it investigates the role of sound for interaction with everyday objects, urban architecture, people, media devices and networks, and allows for a new perspective on playful interactions in and with our media-saturated cities. Some questions raised during the course are: What are the temporal, spatial and aesthetic qualities of sound in urban space? How can we orchestrate, tune, sonify or silence the complex multi-sensory environment of the city? Can we play the media city like a musical instrument? How can sound facilitate or disturb navigation and orientation in urban space? Can we invent alternatives to speakers or headphones for sound output? What role does sound and music experienced in public space play in the cultural identities of cities? Are there different modes of listening? How does sound relate to and shape our perception of scale, speed and rhythm in architecture? After a brief introduction to the physics of sound and acoustics, the class will look at upcoming areas of research, art and design dealing with sound, media and urban space, such as Sound Studies, Locative Media, Sonic Interaction Design and Mobile Music. The field of Sound Studies explores the history and contemporary status of sounds, such as church bells, skateboards, foghorns, highways, cell phones. There is also a growing interest in the intersection of architecture and sound. Locative Media is a form of digital media with a sense of place and a direct connection to urban space. Sonic Interaction Design is concerned with the exploitation of sound as one of the principal channels conveying information, meaning, and aesthetic/emotional qualities in interactive contexts. The field of Mobile Music explores how we can take advantage of our urban mobility to make, experience or share sounds or music. An important part of the class will consist of practical outdoors sessions in the urban environment (e.g., sound walks, sonic playtable, interaction re-labeling) that will highlight how we interact with urban space and media via sound. Critical discussions of these will be conducted in class in the light of selected short readings, as well as presentations of key examples of works from the fields and histories of sound art, media art and public art. Finally, students will conduct mini-projects in which they will develop their own concepts and question, challenge, disturb and play with the role of sound in urban media interaction. Projects can be very low-tech or not use technology at all; therefore no technical skills are required. In terms of course requirements, students are expected do a short oral presentation in a session of choice (in pairs); to complete one short written reflection text upon the practical exercises; conduct a mini-project individually or in pairs; and write one short essay at the end of the course about their project and how it relates to the fields of Sound Studies, Locative Media, Sonic Interaction Design and/or Mobile Music.
