“Urban atmosphere,” which concerns the intangible features that give “life” to everyday environments, provides an important means of appreciating the self-image and narratives of marginalized towns and localities. This paper posits listening critically to sonic environments as a means of exploring and reframing urban atmosphere. Listening practices with a sound art-oriented approach can empower local inhabitants and municipalities by inspiring the collaborative governance of immaterial commons. Sonic urban design, which converges sound art and planning, is presented as a tool for developing awareness of the “uniqueness” and fragility of urban atmosphere through listening activities and proposed community-based sonic guidelines. The initial outcomes of my participation as an artist in residence during the sound art festival Liminaria 2018 provides a recent example of sonic urban design in practice.
