What primary acoustic goal defined the architectural design of the Theatre of Epidaurus?
Intelligibility
The ancient Greeks, exemplified by the Theatre of Epidaurus, were masters of architectural acoustics focused not on silence, but on projection and clarity. Their design utilized semi-circular seating and precisely angled, tiered rows specifically to carry the speaker’s voice clearly across large distances to every member of the audience. The material used, such as limestone, also aided in projecting sound while scattering harsh reflections. The objective was achieving high speech intelligibility so that spoken words remained understandable over the required distance, which contrasts sharply with the modern goal of soundproofing, which aims for isolation and the elimination of external sounds.
