In acoustics, a beat is an interference between two sounds of slightly different frequencies, perceived as periodic variations in volume whose rate is the difference between the two frequencies. With tuning instruments that can produce sustained tones, beats can readily be recognized. Tuning two tones to a unison will present a peculiar effect: when the two tones are close in pitch but not identical, the difference in frequency generates the beating. The volume varies like in a tremolo as the sounds alternately interfere constructively and destructively. As the two tones gradually approach unison, the beating slows down and may become so slow as to be imperceptible. Video: - (20hz) Beat Frequency - - (190hz) Base Frequency Beta Brain Waves Information ( 13 to 30Hz) : •14 Hz - Awakeness, alert. Concentration on tasks, Focusing, vitality. •16 Hz - Bottom of hearing range. Releases oxygen/calcium into cells •12 - 15 Hz - Relaxed focus, improved attentive abilities •13 - 27 Hz - Promotes focused attention toward external stimuli •13 - 30 Hz - Problem solving, conscious thinking •18-24 Hz — Euphoria, can result in headaches, anxiety ---------------- What are beta brainwaves? --------------- Beta brainwaves are considered fast brain activity. Beta brainwaves are brainwaves that cycle within the range of 12 -- 38 Hz and are usually generated in the brains left-hemisphere. Beta waves kick in when logically thinking, feeling stressed, and feeling tense. Beta is generally thought of as a normal rhythm and is dominant in people who are alert, anxious, or have their eyes open. Beta brainwaves are considered to be the normal brainwave pattern in healthy adults. Most children and teenagers have dominant theta and alpha brainwave patterns. There isn't a single brain wave pattern is better than the others -- so don't think beta brainwaves are some sort of miracle that your children need! If you happen to be deficient in the beta brain wave range, increasing them may feel like a miracle! --------------Benefits of increasing beta brainwaves----------- •Ability to think quickly •Highest levels of focus •Goal oriented •Increase in I.Q •Become more social •More energy --------------WARNING----------- As goes for anything, too much beta activity can be a bad thing. By no means would it be a good idea for you to increase a brainwave that you already have high levels of. In fact, there is a real possibility you may experience the negative effects of beta brainwaves, as they can cause anxiety, muscle tension, paranoia, and other related stressful effects. Categoria
