Ancient “Super-Acoustics” technology used on Malta

Researchers detected the presence of a strong double resonance frequency at 70Hz and 114Hz inside a 5,000-years-old mortuary temple on the Mediterranean island of Malta. The Ħal Saflieni Hypogeum is an underground complex created in the Neolithic (New Stone Age) period as a depository for bones and a shrine for ritual use. A chamber known as "The Oracle Room" has a fabled reputation for exceptional sound behavior.

During testing, a deep male voice tuned to these frequencies stimulated a resonance phenomenon throughout the hypogeum, creating bone-chilling effects. It was reported that sounds echoed for up to 8 seconds. Archaeologist Fernando Coimbra said that he felt the sound crossing his body at high speed, leaving a sensation of relaxation. When it was repeated, the sensation returned and he also had the illusion that the sound was reflected from his body to the ancient red ochre paintings on the walls. One can only imagine the experience in antiquity: standing in what must have been somewhat odorous dark and listening to ritual chant while low light flickered over the bones of one’s departed loved ones.

Sound in a Basso/Baritone range of 70 – 130 hz vibrates in a certain way as a natural phenomenon of the environment in the Hypogeum, as it does in Newgrange passage tomb, megalithic cairns and any stone cavity of the right dimensions.  At these resonance frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy.  Echoes bounce off the hard surfaces and compound before they fade.  Laboratory testing indicates that exposure to these particular resonant frequencies can have a physical effect on human brain activity.

What is astounding is that five thousand years ago the builders exploited the phenomenon, intentionally using architectural techniques to boost these "super-acoustics". Glenn Kreisberg, a radio frequency spectrum engineer who was with the research group, observed that in the Hypogeum, "The Oracle Chamber ceiling, especially near its entrance from the outer area, and the elongated inner chamber itself, appears to be intentionally carved into the form of a wave guide."

The same people who created Ħal Saflieni also engineered a complete solar calendar with solstice and equinox sunrise alignments that still function today in one of their above-ground megalithic structures. There is no question that a sophisticated school of architectural, astronomic and audiologic knowledge was already in place a thousand years before the Egyptians started building pyramids.

Ancient ‘Egyptian blue’ pigment points to new telecommunications, security ink technology

leave a comment »

A bright blue pigment used 5,000 years ago is giving modern scientists clues toward the development of new nanomaterials with potential uses in state-of-the-art medical imaging devices, remote controls for televisions, security inks and other technology.

That’s the conclusion of an article on the pigment, Egyptian blue, in the Journal of the American Chemical Society.

Tina T. Salguero and colleagues point out that Egyptian blue, regarded as humanity’s first artificial pigment, was used in paintings on tombs, statues and other objects throughout the ancient Mediterranean world. Remnants have been found, for instance, on the statue of the messenger goddess Iris on the Parthenon and in the famous Pond in a Garden fresco in the tomb of Egyptian “scribe and counter of grain” Nebamun in Thebes.

They describe surprise in discovering that the calcium copper silicate in Egyptian blue breaks apart into nanosheets so thin that thousands would fit across the width of a human hair.

The sheets produce invisible infrared (IR) radiation similar to the beams that communicate between remote controls and TVs, car door locks and other telecommunications devices. “Calcium copper silicate provides a route to a new class of nanomaterials that are particularly interesting with respect to state-of-the-art pursuits like near-IR-based biomedical imaging, IR light-emitting devices (especially telecommunication platforms) and security ink formulations,” the report states. “In this way we can reimagine the applications of an ancient material through modern technochemical means.”
