By Tom Danley • March 10, 2017 The Great Pyramid of Giza. Brain Waves, Sound Waves One of the latest rages in controlling one’s brain wave state are the light/sound machines which use black glasses and headphones with flashing lights in the glasses and LF pulsing sound in the headphones to literally trap your brain into synchronizing at the pre-programmed frequency. It would seem like sort of a meditation ride. You need no practice to do it. It just takes you. The frequency range, which causes this effect, is at the low end of the audio spectrum or even below the LF that we hear (infrasound). Low-pitched sounds have long been known to cause emotional responses. The massive pipe organs of the ancient cathedrals were built (at considerable difficulty one should remember) to produce powerful LF sounds to frequencies below “audibility” or infrasound because of the powerful emotional and physiological effects they have on people. Music and movie sound tracks are reproduced loudly to have an emotional effect on most people. Before the industrial revolution (and the attendant noise pollution) humans had more sensitive hearing than we do now. Accordingly, to the ancients, the sound in the pyramids would seem even more powerful. How Did We Forget? Apparently man has been intentionally designing acoustic spaces for quite some time. During 1996, A Journal of the Acoustical Society of America paper, authored by Paul Devereux and Robert G. Jahn, detailed a number of ancient structures in England and Ireland which were apparently designed to enhance the bass frequencies in the voice range. Among other conclusions, Devereux and Jahn believed this was done because of the group chanting used in their rituals. Mantra’s were often part of the meditation process and are even now. The dimensions of the Sarcophagus in the main chamber are also such that there’s acoustical reinforcement of the LF voice range as well. As such, it seems obvious that architectural acoustics are simultaneously very old, and yet a virtually new science. The ancients had a grip on these principles, yet acoustic sciences seemed nearly lost for thousands of years. We ask why, yet we have no answer. In many cases, architectural designs made more than 100 years before the computer are still considered to be among the best there are. This is further evidence, it seems, of how cyber-analysis can never fully replace life experience. Still, these days, architectural acoustics exist almost entirely within the computer. One Last Thing Lacking a time machine, one cannot “know” what the designers really had in mind when they built the Egyptian Pyramids. Clearly, they went to an amazing amount of work and had a powerful reason for doing it. Equally clear, they had techniques and skills used in its construction that we are aware of, but what they did looks impossible with what is known about them. Still, it obviously was possible. “High Technology” (aliens, etc.) seems very unlikely as the pyramid’s interior nooks and crannies are very roughly shaped. If they had a laser or other high-tech voodoo tools, logic predicts they would have used them everywhere, not just where it showed. On the other hand, machining marks were visible on the inside of the sarcophagus wall from some “rotary” type cutting process. Obviously they had some mechanical help. Anyone who has been in the Great Pyramid and chanted or hummed will tell you that it feels weird, and that the acoustic effect is powerful. In short, it is possible that the ancient builders may well have been aware that sounds, even inaudible ones, can have a profound effect on one consciousness. The fact that they were able to quarry huge red granite blocks six hundred miles away, transport them, “machine” them to a precise fit and then polish them, implies that there is an ocean about the ancient’s we don’t know — especially regarding their application of acoustic science.
