The archeaoacoustic properties and the historical rituals of two ancient unaergrounu ~Ly~,u~ ~,~ v Malta is more widely known and researched; the second in Italy has been studied by SB Research Group （SBRG] and presents some similarities to the Maltese hypogeum. The results show that archaeoacoustics is an interesting new method for reanalyzing ancient sites, and it uses different study parameters to re-discover forgotten technology which operates on the human emotional sphere. The effect on the psyche of ancient people through the acoustic proprieties suggests that the builders of these sites had knowledge of this process and probably used it to enhance their rituals.
