Infrastructures have a rhythm to their operation and their flow – structurally, sonically, linguistically, and experientially. In the musicality of their daily operational procedures or the cyclicality of their differentiated reiteration across time, in the pulsation of their immediate impact or the accumulated echoes of their long-term repercussions, infrastructures produce the discernable soundscapes within which we are immersed.

Moreover, patterns in the modulations and inflections inherent to infrastructure’s performance bestow this soundscape with a cadenced quality.

Whether in the reverberation of sound in built environments or of discursive language in successive social movements, infrastructure’s acoustics can be experienced both literally and metaphorically. Infrastructures vibrate, ring, rumble, boom, pound, and thump to generate the cacophonies and melodies of everyday life.
