A 15th-century Inca building in Huaytará, Peru, known as a carpa uasi or tent house, may have been designed to amplify low-frequency sounds like drumming. Art historian Stella Nair of UCLA, along with acoustic experts led by Stanford professor Jonathan Berger, is studying the structure's unique three-walled design to understand its acoustic properties. The building survived because a Christian church was built on top of it, stabilizing the stone structure.
