Greek Theater Acoustics: The Real Physics

Описание: Greek theater acoustics work because architecture and materials shape speech clarity—not magic. Using measurements from the Epidaurus theater, we break down how ancient Greek architecture and greek engineering balanced geometry, materials, and audience behavior. Seat-row geometry acts as a spatial filter that suppresses low-frequency crowd noise while preserving consonant-rich speech bands; a hard orchestra floor and a reflective skene supply early energy; hillside placement reduces wind and off-site noise. We also test popular claims about whispers and coin drops against impulse responses and modern models. The result: intelligibility through ensemble design—good, repeatable physics that ancient greek technology exploited at scale.
