Directional Noise-Embedded Audio
A proprietary framework for embedding, encoding, and delivering audio content within directional noise fields. Combines ultrasonic parametric delivery, infrasound entrainment, and psychoacoustic masking for precision spatial audio targeting — without perceptible signal presence outside the target zone.
DNEA exploits the physics of ultrasonic heterodyning — two ultrasonic carriers interact in air and their difference frequency becomes audible only within a defined acoustic convergence zone. Content delivered this way has no perceptible signal presence outside the target radius.
Combined with infrasound interference for physiological priming and phased transducer array geometry for spatial precision, DNEA enables audio delivery applications that are not achievable through conventional speaker systems.
DNEA is the delivery backbone of the EasyZz sleep-learning platform. Content embedded in sleep-safe ambient audio is delivered during detected NREM phases via under-mattress transducers. Vocabulary and structured knowledge reinforced without waking.
Coherent audio delivery within a defined 2-meter target radius. Outside that zone, only ambient noise. Applications include private audio zones, spatial wellness delivery, and precision communication environments.
