_) PSY CHOTROME ~ ELANOLObIcS Building a BINAURAL SIGNAL GENERATOR! by Peter Nielsen - Parascience Technologies There has been a proliferation of Mind Machines recently... These amazing devices typically emit pulsating light n' sound to condition the brain into an altered state of awareness. By simply turning aknob, . neurological patterns associated with various subjective abilities can be triggered and prolonged indefinitely, Random influences are HEARNE FICS eeeecaee excluded. Either you like the idea, oryoudon'tl eeeeeeeece HEAR looking glass. Outer AND inner realms are thereby accessible as objective, yet non-self-existant, modes of inter-dependency. Try this experiment... with your eyes closed, try to focus on where the sounds converging from either side of you merge within. It’s a very nice space that meditators will recognise. I find the sensation like a subtle curtain of undulating pressure within the head... an ideal mechanism for brain-wave capture, once widely used in religious chanting and architectural acoustics. It’s a standing wave of information-carrying energy that can, in terms of its inferred attributes, subliminally affect your health and emotional involvement. This is how a stereo system recreates the ‘presence’ of the band. Inversely, it is also the anatomical reference point in the composer from which the music first arose as symbols. ys eee Back in the lab, we can demonstrate one aspect of this unifying principle with two simple audio oscillators, each feeding into one side of a pair of headphones. By ensuring that the two originating signals can be made to differ by a selectable rate between 3-25 cycles per second (Hz), the mind can be correspondingly stimulated to synthesize its own beta, alpha, theta or delta rhythms..the bi-directional carrier waves of both our level of creativity and perception. See Figure. 2 on the next page for some experiential derivatives of this induced ELF (extreme low frequency) component. This device is called a “Binaural Frequency Generator”, and has been popularized by Dr Monroe in his famous lucid Frankly, P’ve grown complacent about flashing goggles... seductive as they are. Also, in my opinion, they have two minor drawbacks; firstly, a kind of harshness that doesn’t fully address the brain’s own synergetic faculty. Secondly... usually, a lack of provision for setting precise frequencies. You never know exactly where you are, and some psycho-active “windows” are definable to within 1/100th of a cycle per second. Still, they are a valid starting point. This project is more organic in feeling, Its effectrelies on our natural ability to synthesize a third sound, or “beat frequency”, from two external ones. When differing sounds are admitted to each ear, the brain hemispheres conjoin to improvise an internal sensation of noise from the summed waveform interactions. The complimentary left and right brain functions of assertion and receptivity, harmonize in a burst of mutually augmentative perception. This event, also attainable through learned biological resonance, is the doorway to supra-sensory cognition. The resulting holographic sound image imposes directionality, texture and space upon our sense of hearing. In other words, a more real “reality”. When deprived of this form of sensory orientation, such as in a float tank or prolonged spiritual retreat, the isolated mind will cleverly REVERSE this process to project its own “hallucinatory” world from latent impressions. The more common manifestation is dreams during sleep. If consciously invoked, this ordinarily repressed faculty is the key to ESP, past life recall, clairaudience... and the all-pervading cosmic intelligence... the calculated somersault through Alice’s Figure 1 Binaural Frequency Generator 34 Nexus *10
