The magical acoustic secrets of a famous cave known as the “Church of the Devil” have been revealed by researchers.

The Devil’s Cave, called Pirunkirkko, is located in the Kolli mountain range of eastern Finland. It has been used as a meeting place for local sages for centuries Connect with the spirit world using sound.

The 112-foot-long cave was used by shamans for drumming and sound-based rituals. The cave’s sacred use may be due to its strange acoustic properties, now investigated by scientists, a new paper suggests. Magazine Open Archaeology.

“When the acoustician hears it as a resonance, the ancients may have known the presence of the spirit, and the shamanic practitioner may have felt an energy unique to each of them according to their background,” said archaeologist Rieta Ranio. In a statement given by the University of Helsinki.

The researchers took acoustic measurements in the cave, in the cave a A powerful resonance phenomenon. This is because sound waves are stopped between the two parallel walls, generating a shrill tone at frequencies between 219 Hz and 232 Hz. This basically means that any sounds produced in these frequencies will be amplified and lengthened in the tunnel.

“After high-speed broadband noises such as balloon pops, hand claps, and drums, this sound remains audible,” the authors write in the paper. “Alternatively, the bell tone can be excited by singing at the same frequency or an integer multiple. This resonance phenomenon must have been present in historical rituals in the cave.” Because the autopsy report shows that they were under high pressure. – like a scream.”

It is believed that the sages were pounding the rocks, shouting, shooting guns, singing and jumping around the cave, creating the sound of the sound.

“The cave responds to one of the three sung tones—the one corresponding to the resonant frequency—by amplifying it in the song,” the authors write.

One of the most famous sages who used the cave For witchcraft And other magical rituals, there was a man named Kinoline.

“According to legend, Quinoline took his patients to the ‘church’ to talk to the devil about the cause of their illness and cures. Such a healing ritual often involved loud shouting, kicking, shooting and beating,” Renio said.

The researchers think that the cave’s use in rituals came from its amazing acoustic properties, shaping the beliefs and practices associated with the cave.

The authors write: “Such a unique voice may be one of the reasons why Pirunkirko is so important to historians and modernists, as well as to all those who have used the place over time.” “Acoustic research provides new tools for investigating and understanding the religious beliefs and practices reported in Pirinkirkko and similar sites. The study also shows how cultural frameworks guide our senses leading to different experiences and interpretations.”
