The theater is marveled for its exceptional acoustics; which permit almost perfect intelligibility of unamplified spoken word from the proscenium or sk阯?to all 15;000 spectators; regardless of their seating (see Ref.; in Greek). Famously; tour guides have their groups scattered in the stands and show them how they can easily hear the sound of a match struck at center-stage. study by Nico F. Declercq and Cindy Dekeyser of the Georgia Institute of Technology indicates that the astonishing acoustic properties are either the result of an accident or the product of advanced design: The rows of limestone seats filter out low-frequency sounds; such as the murmur of the crowd; and amplify / reflect high-frequency sounds from the stage.
