Boundary Layer Acoustic Phase Canceler with Dual Diaphragm Sensors (Revision 4.1)
Discipline: Applied Anomalies · Lead Researcher: Isolde Chen
OPERATIONAL ABSTRACT
A tactile boundary sensor that isolates and cancels unwanted floor reflections in real time, delivering exceptionally clean direct acoustic sound from live performers. Enhanced revision 4 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Dual opposed electret diaphragms compute real-time acoustic pressure differentials at boundary surfaces, subtracting reflected phase anomalies before analog-to-digital conversion. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
