Site-Specific Coastal Acoustic Reflector Pavilion with Wave Harvesters (Revision 3.2)
Discipline: Acoustic Architecture · Lead Researcher: Dr. Evelyn O'Connor
OPERATIONAL ABSTRACT
An open-air architectural pavilion featuring curved concrete acoustic mirrors that focus incoming ocean wave sound into a central listening amphitheater. Enhanced revision 3 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Parabolic geometry concentrates low-frequency ocean swells at the focal point, while submerged hydrophone strings stream real-time underwater acoustics to embedded spatial speakers. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
