Soundscapes and community organisation in ancient Peru: plaza architecture at the Early Horizon centre of Caylán

The thriving study of acoustic archaeology is here applied to an excavated plaza site in Peru, where the authors show that an intimate sound-space was intended, one which featured panpipe music as well as the spoken word. Their method involved the measurement of three sound levels of speech at various distances from the plaza, giving us an easy-to-use mode of on-site investigation, which will surely win wide application. The study also showed a dramatic change from the use of acoustics in a previous period, where sound was canalised in U-shaped temples in order to address large numbers of people.
