Perceptual Binaural Auditory Mask with Zygomatic Bone Conductors (Revision 5.1)
Discipline: Perceptual Interfaces · Lead Researcher: Nils Holst
OPERATIONAL ABSTRACT
A wearable sound research headset combining open-ear directional acoustic speakers with bone-conduction transducers placed against the cheekbones. Enhanced revision 5 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Direct bone stimulation bypasses the eardrum to transmit high-frequency transients directly to the cochlea, while open-air drivers deliver natural spatial ambiance. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
