Acoustic Architecture — Spatial Listening Stations, Resonant Vaults & Sonic Pavilions

Acoustic architecture at ZIAA spans two scales: the constructed listening room and the found landscape as listening room. Both are measured, not metaphorized. The Salton Subterranean Vault — a 2,400 m² reinforced bunker with an 18.4-second RT60 — serves as an instrument for feedback and ambisonic staging experiments that would destroy a normal room. At the other extreme, desert and coastal field stations are “buildings” with kilometre-scale footprints — distributed microphone, geophone and VLF arrays that turn wind, seismic and atmospheric activity into compositional material.

Built work includes a 32-channel desert sanctuary geodesic array, a sub-glacial 16-channel hydrophone string in Svalbard fjords, and a low-impact coastal pavilion tuned for 1–24 kHz field work. Each station dossier publishes channel count, bandwidth, footprint, coordinates (DMS + GeoCoordinates JSON-LD), instrumentation list and public-access protocol — not as travel brochure but as replication spec for researchers and artists who need to know what a site can hear.

The division closed the loop between architecture and software: vault impulse responses are sampled for convolution engines that let any browser instrument briefly inhabit the vault. This tight cross-link — place ↔ prototype ↔ software — is the entity’s strongest topical cluster for “spatial audio,” “acoustic architecture” and long-tail field-recording queries.

Design validation is acoustic measurement, not rendering. The Vault’s 18.4 s RT60 is a measured T30 mean across 12 source-receiver pairs at 125–4000 Hz, with standard deviation 0.6 s, not a modeled estimate. Geodesic desert array directivity is mapped with a 32-mic spherical array and published as polar plots per prototype. Coastal pavilion tuning is documented as one-third-octave absorption coefficients, not adjectives. Every field station dossier therefore reads as a spec sheet — channelCount, frequencyRange, physicalFootprint, instrumentationList, publicAccessProtocol — because the architecture’s research claim is that it can be rebuilt elsewhere.

Software-architecture loop is closed: vault impulse responses are deconvolved and shipped as convolution reverbs that run in the Acoustic Bench and SYNTHESIS//SIGNAL at 48 kHz/24-bit. A browser instrument can therefore briefly inhabit the Vault, A/B’d against dry, with documented latency and headroom. This is not a metaphor for “inspiration from space” but a measurable transfer function, cross-linked as Dataset distributionUrl from the field station page to the prototype’s acoustic profile. That chain — Place → Dataset → SoftwareApplication — is the division’s strongest topical cluster for “acoustic architecture” and “spatial audio.”
