The ancient theater of Epidaurus is renowned for its exceptional acoustics, which allow spectators in the highest rows to clearly hear speakers on the stage. For decades, researchers attributed this phenomenon primarily to the theater's slope and the prevailing winds of the region. However, a recent acoustic study conducted by Nico Declercq and Cindy Dekeyser revealed that the row seat structure itself acts as a sophisticated acoustic filter. By reflecting high-frequency sounds back toward the audience while trapping low-frequency background noise like the rustle of wind, the limestone seats enhance the clarity of human speech. Thus, the physical geometry of the seating, rather than external environmental factors, is the primary driver of the theater’s legendary auditory quality.
