[4]The acoustics of the Greek theater

One of the unique aspects of the Greek theatre is its exceptional acoustics. In ancient times actors did not use microphones to amplify their voices, but the spectators on the highest steps were able to hear the performances.
The secret to the acoustics in Greek theatres is connected to their semicircular shape, which helps to “hold” sound.
