Site-Specific Coastal Acoustic Reflector Pavilion with Wave Harvesters

PROT-031: COASTAL-PAVILIONCLEARANCE: 1-ALPHASTATUS: ACTIVE BENCHYEAR: 2021

Discipline: Acoustic Architecture · Lead Researcher: Dr. Hawa Mansour

OPERATIONAL ABSTRACT

An open-air architectural pavilion featuring curved concrete acoustic mirrors that focus incoming ocean wave sound into a central listening amphitheater.

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.
