Acoustic studies of ancient monuments is relatively scarce before the Greek and Roman eras when amphitheatres were central to these societies. Studies into the behaviour of sound in Neolithic archaeological sites show recurring and interesting acoustic effects, which would have been audible to our ancestors. Understanding the acoustics helps archaeologists and historians understand what the people using or constructing these places would have intended. This project intends to develop a methodology for a new area in archaeology and acoustics. The project involves the study of ancient sites around the world and includes measurements and modelling with room acoustic software, finite element analysis and wave based acoustic models.
