Abstract
The Recycled Soundcape is designed as a system through which to explore the auditory aspects
of experience in the city, and the possibility of offering relief through sound and relational
design from the prevailing and often stressful urban flow. The result is an interactive system
for the public orchestration of an urban sound ecology. It consists of a set of kinetic, humanscale
interfaces which seek to create diversions and concentrations of attention within the
sonic context of a location, by facilitating reflective activity in the public sphere, in the course
of which an acoustic landscape may be augmented, modified and performed. It offers the
opportunity play with surrounding sounds, to tune the composition of a sonic environment, and
the possibility to listen to and to record noises – human, natural, machine, electronic – which
are otherwise difficult to take notice of, and which nonetheless contribute to the
characteristics of a place over time, composing its evolving memory in sound.
