Señal de Auxilio

SI ESTÁS ATRAPADO/A: Pon el teléfono cerca de una abertura, a volumen máximo, y usa la señal en ráfagas cuando escuches rescate.

⚠ RESCATISTAS: Coordinen la señal con los períodos de silencio; no la dejen sonando continuamente.

TECHNOLOGY

THRENODY is a novel alert signal generation system that produces non-repeating, psychoacoustically optimized alarm tones. Each activation generates a unique signal — the same alarm never plays twice, eliminating habituation, the primary failure mode of conventional alert systems.

Frequency Range

460 – 3,800 Hz

FEMA CPG 1-17 base, extended to ear canal resonance zone

Startle Onset

< 5ms rise time

Blumenthal et al. 2005 — involuntary brainstem reflex

Roughness Clusters

8–14 voices within critical bandwidth

Vassilakis 2005 — maximum psychoacoustic irritation

Anti-Habituation

Aleatoric + silence gaps

Orienting response reset per re-onset

Binaural Entrainment

16 Hz beta-band offset

Garcia-Argibay et al. 2019 — cortical arousal

Perceptual Urgency

Shepard tone illusion

Endlessly ascending pitch — unresolvable tension
