Resonance explores how materials, structures, and physical interactions transform movement and energy into audible phenomena, shaping the timbre and acoustic character of urban environments.
Each step on this steel pedestrian bridge generates vibrations that propagate through the structure. The steel deck and railings respond according to their material properties, mass, and connections, radiating sound as the bridge is set into motion. Striking different elements of the steel structure reveals their individual resonances, producing distinct metallic tones and exposing the bridge as an often unnoticed urban instrument.
Wheel–rail interaction excites vibrations that produce the characteristic squeal. Surrounding architectural structures further shape the sound field by reinforcing certain frequencies through acoustic reflections.
The same moving car sounds different on different surfaces. Cobblestones fragment the sound into irregular, highly textured impulses, while asphalt produces a smoother, more continuous sound. The material itself shapes the timbre of motion, revealing how urban surfaces actively colour the acoustic environment.
The crossing signal acts as an urban pulse, introducing a regular rhythmic layer into the acoustic environment. As the tram enters a curve, friction between the wheels and rails generates a characteristic tonal resonance. The interaction between movement, material, and track geometry transforms the tram into a temporary acoustic instrument.
Wave motion transfers energy into the landing pier, exciting structural vibrations that radiate as sound. The rhythm of the resulting sound is directly shaped by the movement of the water, transforming the waves themselves into an audible pattern. The pier becomes part of a coupled system of water, material, and motion.
The sound inside the tram shifts continuously with the changing infrastructure beneath it. These variations reshape the acoustic field throughout the ride, becoming especially audible when crossing a bridge, where the carriage resonates as a whole.
The interaction between wheels, rails, and the steel viaduct generates metallic tones and squeals as friction excites structural vibrations throughout the system. Reflections from surrounding buildings shape the acoustic field, reinforcing certain frequencies and increasing the perceived presence of the sound within the urban environment
Inside the moving train, the vehicle itself becomes a resonant acoustic system. Vibrations generated by motion excite the structure and interior materials, producing dominant high-frequency tones and continuously changing resonances. As the train enters tunnels, the acoustic field transforms dramatically, revealing how different spaces reshape the experience of movement.
