Archaeoacoustics is a relatively new approach to analyze any archaeological sites that has interesting acoustic characteristics. It can be used to demonstrate sound occurrences believed to have been incorporated into the design by the architects of certain structures. Another aspect of archaeoacoustic research can understand how such structures affect brain activity, useful during rites where an altered state of mind intensifies the experience. Natural phenomena can also influence the psychological state for example by inducing mystical states. We have demonstrated ancient civilizations had some knowledge of this phenomena, through understanding the significance specific locations were choosen for buildings such as temples. Using digital recording equipment, it is now possible to record non-audible sound frequency bands. These bands have a direct effect on the human body and mind without a person being aware of the existence of their accompanying mechanical vibrations. The hypothesis of SB research group is that at some archaeological sites, exists a measurable natural audio or electromagnetic phenomena that enhance its mystical properties. Following this line of research, interesting archaeoacoustic effects have been discovered at a number of sacred sites from Malta to Turkey and Serbia to Italy. Incorporating a neurophysiological approach, is adding weight to this hypothesis.
