Cities are designed by what we can see and measure; they are lived through what we hear and feel. CDA Sonic Drift introduces listening as an urban strategy: it links situated recording and public feedback to planning questions (density, mobility, greenspace) and makes Sonic Space Shifts legible for planning and policy.

CDA Sonic Drift is an artist-led audio essay integrated with a geospatial workflow. Focused on Brussels North’s Chaussée d’Anvers (CDA), it maps Sonic Space Shifts through field recording, differential listening, and AI-assisted analysis (AER/USS), in collaboration with CERTH (GDPR-compliant rooftop logging; AER/USS integration).

Combining sound art and planning methodologies, the project offers a critical planning perspective on how planning decisions shape the city’s sonic experience. It challenges conventional analysis by foregrounding the sonic affective dimension of urban environments and the role of public participation in planning processes.

The audio essay presents the outcomes as a mixed-media installation—dubplate listening, risograph scores, and GIS-based (dis)comfort maps—inviting public reflection on acoustic dis/comfort and on the use of AI in planning practice.
