Street art opens a new, broad research field in the context of
urban communication and sound aesthetics in public space.
The primary focus of this article is the relevance and effects
of using sound technologies and audio devices to shape urban
landscape and soundscape.
This paper examines the process of developing an alternative
type of street art that uses sound as its medium. It represents
multiple audio device prototypes, which encourage new
chances for street artists and activists to contribute their
messages and signs in public spaces. Furthermore, it
documents different approaches to establishing this alternative
urban practice within the street art and new media art field.
The findings also expose a research space for sound and
technical interventions in the context of street art.
