Acoustical Amplifiers - What Are They?

Archaeologists think that part of the design of stonehenge involved creating something that would naturally amplify music and chanting. The first true sound guy was gaspar p chotto, who wrote a book on acoustics called magave universalis in 16 57. Gothic cathedrals were all about acoustics; these churches were very echoy which resulted in music like this. This also explain why mass was chanted instead of spoken.
