Stonehenge enhanced sounds like voices or music for people inside the monument
Welcome to Soundhenge. Better known as Stonehenge, this ancient monument in southern England created an acoustic space that amplified voices and improved the sound of any music being played for people standing within the massive circle of stones, a new study suggests. Because of how stones were placed, that speech or music would not have projected beyond Stonehenge into the surrounding countryside, or even to people standing near the stone circle, scientists report in the October Journal of Archaeological Science. To explore Stonehenge’s sound dynamics, acoustical engineer Trevor Cox and colleagues used laser scans of the site and archaeological evidence to construct a physical model one-twelfth the size of the actual monument. That was the largest possible scale replica that could fit inside an acoustic chamber at the University of Salford in England, where Cox works. This room simulated the acoustic effects of the open landscape surrounding Stonehenge and compacted ground inside...
