Binaural beats
Binaural beats To experience the binaural beats perception, it is best to listen to this file with headphones on moderate to weak volume – the sound should be easily heard, but not loud. Note that the sound appears to pulsate. Now remove one earphone. Note that the pulsations disappear completely. Repeat with your other ear. The brain produces a phenomenon resulting in low-frequency pulsations in the amplitude and sound localization of a perceived sound when two tones at slightly different frequencies are presented separately, one to each of a subject's ears, using stereo headphones. Binaural beats reportedly influence the brain in more subtle ways through the entrainment of brainwaves[3][8][9] and provide other health benefits such as control over pain.[10][11] Acoustical background[edit] Interaural time differences (ITD) of binaural beats Binaural beats can also be experienced without headphones; they appear when playing two different pure tones through loudspeakers.

Octave The octave has occasionally been referred to as a diapason.[2] Theory[edit] An example of an octave, from G4 to G5 For example, if one note has a frequency of 440 Hz, the note an octave above it is at 880 Hz, and the note an octave below is at 220 Hz. The ratio of frequencies of two notes an octave apart is therefore 2:1. Brain Hacking: Scientists Extract Personal Secrets With Commercial Hardware Chalk this up to super-creepy: scientists have discovered a way to mind-read personal secrets, such as bank PIN numbers and personal associations, using a cheap headset. Utilizing commercial brain-wave reading devices, often used for hands-free gaming, the researchers discovered that they could identify when subjects recognized familiar objects, faces, or locations, which helped them better guess sensitive information. Security interrogators could benefit most immediately from the new brain hacking technique, since it would reveal when suspects are actually familiar with the face of a potential accomplice.

Binaural Sounds Sleep Music Natural Sleep Aid To Dreams Unsettled Format: MP3, stereo, high quality Length: 30 mins, 40MB Type: Sleep track (for dream induction) Description: Fancy a dream that's a bit... disturbing? Explore your mind, find your soul, and see who comes out the other side. Medieval music Medieval music is Western music written during the Middle Ages. This era begins with the fall of the Roman Empire and ends sometime in the early fifteenth century. Establishing the end of the medieval era and the beginning of the Renaissance is difficult; the usage in this article is the one usually adopted by musicologists. Overview[edit] Instruments[edit] Genres[edit] Sea Shadow (IX-529) Sea Shadow (IX-529) was an experimental stealth ship built by Lockheed for the United States Navy to determine how a low radar profile might be achieved and to test high stability hull configurations which have been used in oceanographic ships. Sea Shadow was built in 1984 to examine the application of stealth technology on naval vessels. She was used in secret until a public debut in 1993. In addition, the ship was designed to test the use of automation to enable the reduction of crew size.

Brain Waves Predict Video Game Aptitude October 25, 2012 Caption: University of Illinois postdoctoral researcher Kyle Mathewson and his colleagues discovered that they could predict how quickly a person would learn a new video game by looking at the electroencephalogram of the person’s brain at the start of play. Credit: L. Brian Stauffer redOrbit Staff & Wire Reports – Your Universe Online A person´s aptitude for video games can be predicted by their brain waves, according to a new study published in the journal Psychophysiology. Consonance & Dissonance Consonance[edit] The definition of consonance has been variously based on experience, frequency, and both physical and psychological considerations (Myers 1904, p. 315). These include: Perception Blend/fusion: perception of unity or tonal fusion between two notes (Stumpf[full citation needed]; Butler and Green 2002, p. 264)Frequency ratios: with ratios of lower simple numbers being more consonant than those that are higher (Pythagoras[full citation needed]). Many of these definitions do not require exact integer tunings, only approximation.[vague][citation needed]Both Continuity: consonances are continuous and dissonances are intermittent in sensation, determined by coincidence of partials (Helmholtz 1954 [1877],[page needed]).
