The Light and Sound Dictionary… continued

Fill-in-blanks is a technique of creating light and sound programs by selecting one of a number of available program profiles, and specifying the frequency range and control options to be used. Thus a custom program can be created with four menu selections.

515 Sound only stimulation. Christopher Oliver and Michael Landgraf, developers of the 515 Dual Independent Binaural Beat Generator, present a new concept in mind machines: Virtual 515 Mindmachine CD. This audio CD turns any CD player into a powerful mind machine. The Virtual 515 Mindmachine CD contains the same sessions as the original 515 hardware unit in a format called LoopLogic(TM). There are 5 LoopLogic(TM) sessions on the disc: 1. Energize (Beta) 10:09; 2. Relax (Alpha) 20:16; 3. Learning (Theta) 10:10; 4. Visualization (Alpha/Theta) 7:10; 5. Sleep (Delta) 26:10.

Frequency refers to the primary rate of pulsed light (visual) and pulsed tone (auditory) stimulation produced by a light and sound session. It is how fast the lights and sound are at one moment on, then at the next moment off. In other words, how fast each form of stimulation is pul-sating. In terms of binaural beats, frequency refers to how often the amplitude is being modulated. Light and sound sessions utilize the same frequency range as the brain, i.e., brain waves. Frequency is properly the rate at which any periodic event repeats, but in light and sound machines it is used more specifically to refer to the primary rate of visual and auditory stimulation — to the eyes, it is how fast the lights are flickering, to the ears, it is how often the sound is pulsed on and off, (pulsed tones) or how often the amplitude is modulated (binaural beats). Frequency, like pitch, is measured in Hertz. The frequencies of stimulation in light and sound systems are in the brain wave frequency range.
