Abstract – The term "archaeoacoustics" does not simply mean the study of sound in archaeological contexts, but also the study of all physical phenomena in these sites. Using an archaeoacoustic approach it is possible to measure the frequencies of natural sounds and magnetic fields of archaeological sites and to interpret their possible sacred function. In previous research our research group (SBRG - Super Brain Research Group), an interdisciplinary team of researchers from various European countries, has demonstrated in some ancient temples the existence of a relationship between mechanical vibrations or magnetic fields induced by natural phenomena and brain activity. For the pyramid of Bomarzo, an ancient archaeological site in Lazio (Italy), we applied the same standard of research that we have used for several years. It is without doubt that the Bomarzo pyramid area owns typical characteristics of similar sacred sites we have previously examined in other locations. The presence of 14Hz almost everywhere at different volumes in the Bomarzo pyramid area is a feature we have often met with at other sacred sites such as Sogmatar and in Göbekli Tepe in South Anatolia where it was also possible to localize a similar powerful magnetic field as in the Bomarzo pyramid.


Keywords – sound, archaeoacoustics, Bomarzo, pyramid.

Archaeoacoustic approach of the Rotunda in Bény

**Department of Medical Sciences, University of Trieste and SBRG, Italy



Abstract - We would like to draw the attention to a medieval sacred place in Central Europe in the Carpathian basin, where unusual sound phenomena can be experienced. We focus our research on the „12 Apostoles’ Rotunda” of Bény. The settlement used to belong to the Hungarian Kingdom for centuries during the Middle Ages and also continuosly until the first part of the 20th century. Now it is situated in the southern part of Slovakia. Recent studies suggest that the rotunda was already built by the 10-11th century, which raises more questions about who built it and for what purpose. The unique feature of the Rotunda are the 12 mysterious vaulted niches within. Each of these niches strengthens different resonances, which gives a unique sound to the human voice there, according to our hypothesis they were very probably tuned on purpose. In 2016 and 2017 fieldwork was undertaken to test the rotunda’s archaeoacoustic and resonant properties. Equipment, methods, results with our conclusion are described in this paper.


Keywords - acoustics, resonance, rotunda, niches, medieval, Central Europe.

Fireplace and holy altar in Curiceta at Apuan Alps, Italy

Abstract - The Apuan Alps, High Versilia and Garfagnana are part of the Apuan Alps Park, and are rich in petroglyphs and archaeological finds which are, in part, unknown and not precisely datable. These areas have been inhabited since Neolithic times but, the meaning and the reason for signs engraved on stone, is unclear. The Apuan Alps were chosen as a dwelling by people who left many ancestral and Christianity signs including sacred altars, thrones and artefacts carved in stone. This area acts like a stone atlas revealing our past and our roots. The Curiceta site is located inside a thick forest of chestnut trees, in an area where dried stone terraces are perfectly preserved. The first building approached along the path, is the so-called “fireplace”, a large flat stone that protrudes from the ground and surrounded by a series of aligned stones where, most probably, a fire was lit. Behind the big stone, is a cavity where the smoke could emerge. The lower part of the flat stone features a ”handle” carved in the rock, its function is still unknown. Along a short stretch of the uphill path protected by a high dry stone wall, lies the sacred stone altar. This enigmatic structure has revealed many surprises during the tests performed with electronic instruments. This altar is carved from a single block of stone and consists of a backrest and a horizontal supporting surface. From the left side, there are inclined planes which climb down, below these one can find a vertical groove. The altar features the same carved handle found on the ''fireplace''. Rock altars are very common around the world, for example throughout Southern Italy and the Middle East but, in High Versilia this is the only one example. Archaeoacoustic analysis of the altar found a dominant and powerful frequency present of between -47 and -50db at 25 – 28Hz. A second peak of infrasound at 15-16Hz was also found. This inaudible acoustic characteristic is commonly found at sacred sites, such as the Neolithic temples of Malta (Tarxien – Xaghra Stone Circle). These same vibrations are present near the altar but at a much lower volume. In this case the loudest volume was found directly under the altardecreasing as one walks away from it. In both cases, the most likely source of this frequency is from underground water. The emotional state of eight volunteers was analysed using a TRV camera. 7/8 felt emotionally uncomfortable or uneasy. Based on these results, a hypothesis was formulated on the function of the Curiceta’s site. The two stone structures are connected. On the altar, sacrifices were probably, made, with blood flowing along the left side to the groove on the floor. The fireplace, could have been used to burn the bodies or maybe just some organs.

Definitive Results of Archaeoacoustic Analysis at Alatri Acropolis, Italy

   **Super Brain Research Group, Italy



Abstract Our research group has used archaeoacoustic methodology over the last seven years. Archaeoacoustics has enabled us to explain some of the enigmas of ancient archaeological sites that were not previously possible to explain through other methods. Our hypothesis suggests the exposure to certain non-audible vibrations could have a significant effect on the psyche of those who came for prayer or rituals, facilitating access into a mystical state. Archaeoacoustic methodology was utilised to study Alatri acropolis in Italy. The cathedral of Alatri is located at the highest point in the town of Alatri which sits on top of a Cyclopean temple. We sought to understand why this temple was built in this location. Using a number of protocols we discovered very strong and significant low vibrations (seismic waves) continuously emitted originating from below the ground. Even though ancient people did not posses the same equipment we have today, they would have been aware of the conditions required to achieve such a mystical state, perhaps by simply sensing they were closer to God in a given location. The seismic waves appear to arise from a geological fault located on the side of the hill where the town has stood since ancient times. The presence of such seismic frequencies increases the effect of any rituals by enhancing the psyche of the participants due to their influence on human brain waves. This suggests the builders of this temple had some knowledge of their effect and offers a possible explanation as to why the temple was built on this particular hill and not on any of the surrounding hills.

Archaeoacoustic Analysis in Enclosure D at Göbekli Tepe in South Anatolia, Turkey

Abstract— We made an archaeoacoustic exploration at Enclosure D in the Göbekli Tepe archeological site. This site is the most ancient archaeological location recognized by archaeologists all over the world. It was dated 7,000 years before the Egyptian pyramids. Thanks to the site’s discoverer we had the possibility to record the vibrations coming from the subsoil, magnetic fields and the sound produced by hitting with hand on central pillar n.18. The results are amazing and confirm that Göbekli Tepe has the same archaeoacoustic aspects of many other typical sacred sites we have studied in Europe and Minor Asia. However the most interesting finding was understanding that the pillar we examined is probably at the centre of a sophisticated mechanism of vibrations and magnetic fields affecting the brain. This discovery is in contrast with our knowledge of the level of technology produced by the civilization who built these sacred temples. Our results have to be considered as preliminary results, however due to the death of the person who discovered the site and the current geopolitical situation in Turkey we cannot continue the research. We hope other researchers will be able to confirm our results in future.

Keywords – archaeoacoustics, Göbekli Tepe, low frequency sound.
