I’m continually impressed by the sophistication of technology from years back. Most theaters have points marked before a performance on where to stand, but this was done for acoustics. The Romans built this theater in such a way that there’s a point in the front where simply talking will be loud enough for the whole audience to hear, as if you’re speaking into a microphone with speakers. Natural amplification! Do modern theaters and public speaking places do this? Obviously I tried it – while we were talking I stepped on the marked square and people that were in the upper deck could hear me without raising my voice. I wish I had a photo of the startled look of the tourists taking photos from the top. See below.
