⌖ Sámi yoik suppression · Kautokeino (Guovdageaidnu), Sápmi, Norway · 1720s-present
Attenuation Floor (1852-2024)
Cultural assimilation operates identically to psychoacoustic noise cancellation: it does not destroy the original signal, but engineers an inverse acoustic environment that forces the indigenous frequency to a mathematically imperceptible noise floor, only to later extract that engineered silence as a commercial commodity.
Overhead transducer arrays emit inverted phase waves to cancel traditional vocal frequencies. · motion: destructively interfering with the cultural resonance
wall text
Inside a reconstructed mission church, an overhead parametric array tracks vocal formants in real time. The installation transposes feedforward active noise cancellation (ANC) and digital spectral gating onto historical assimilation policies in Sápmi. When vocalizations matching traditional yoik pentatonic profiles are registered by DSP algorithms, the system computes an exact 180-degree inverted acoustic waveform, projecting destructive anti-phase sound directly at the source. Assimilation is materialized not as physical violence, but as acoustic nullification—engineering an artificial environment where indigenous frequencies are mathematically flattened to a -80dB noise floor. The accompanying spectrogram documents this systematic suppression across ecclesiastical records from 1720 to late-20th-century state assimilation programs.

anchor facts used
- Missionary Thomas von Westen's 1720s confiscation of Sámi runebomme drums and criminalization of the yoik as pagan witchcraft.
- The Laestadian religious awakening of the 1850s in Kautokeino, which formally banned the yoik as the 'devil's music' within church and community spaces.
- The formal Fornorskning (Norwegianization) policy (1851-1980s) that enforced strict linguistic and cultural erasure in state schools.
- Contemporary extraction where indigenous vocal stems are sampled and monetized as royalty-free 'ethereal' textures in global pop and cinematic scores.
mechanism
- Fast Fourier Transform (FFT) spectral analysis — Archival church records and fine ledgers are algorithmically correlated with contemporary yoik recordings to generate an FFT frequency profile of the exact microtonal and pentatonic signatures historically targeted by state missionaries.
1. Profiling the Target Frequency - Spectral Noise Gating — Live environmental microphones monitor the exhibition space; when the DSP algorithm detects human phonation matching the yoik FFT profile, a hard noise gate engages, instantaneously attenuating the audio output of the room to -80dB.
2. Algorithmic Silence - Feedforward Active Noise Cancellation (Phase Inversion) — Overhead parametric acoustic arrays emit an exact 180-degree out-of-phase anti-noise wave aimed precisely at the detected vocalizer, physically eliminating the sound waves in mid-air through destructive interference.
3. Enforcement via Nullification - Psychoacoustic Masking (Perceptual Audio Coding) — The data of the phase-inverted anti-noise—the exact mathematical shape of the erasure—is compressed into lossy WAV files and sold on a digital marketplace as royalty-free 'atmospheric ambient' sample packs for pop producers.
4. Commodification of the Void

SCORE 4/5 after 2 attempt(s)
READS: The destructive interference of the superimposed audio waveform, executed by suspended directional speaker arrays within a mission church space, cleanly demonstrates real-time phase cancellation.
FAILS: The commercial extraction phase of the thesis is absent, focusing solely on acoustic nullification without showing post-suppression monetization.
