"An interesting acoustical study by G.C. Izenour seems to support the idea that the upper section was built during the Hellenistic period. He concluded that an actor speaking on the orchestra floor would not be able to project all the way to the upper level of the cavea. Only after the invention of the two-level stage (and the enlarged mask, which could have help with projection) would it have been possible for the actor to expand his speaking range to the upper level (Izenour 258)."
