Archaeoacoustics offers a new way to interpret anthropological questions pertaining to ancient architecture and populations. Studies conducted at a number of ancient sites throughout Europe and Asia, have found the presence of natural phenomena capable of influencing the human brain. Earlier studies show that ancient populations most likely through use of empirical methods chose the location of their ceremonial sites for this reason. In Xaghra Hypogeum a stone circle located on the island of Gozo, Malta, infrasounds and audible low frequencies capable of affecting the brain were discovered. The caves and surrounding stones act like a musical box amplifying the natural sounds present and it is possible the natural caves could have been modified to enhance this aspect. Similar natural characteristics were also discovered at other archaeological sites in Europe and Asia, including Epidauros in Greece and Gobekli Tepe in Turkey. This is the third and final article on results of our researches in Malta e Gozo islands (Mediterranean Sea) from archaeoacoustic point of view.
