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.
History[edit] 0:02 Inaudible High-Frequency Sounds Affect Brain Activity: Hypersonic Effect. Abstract Although it is generally accepted that humans cannot perceive sounds in the frequency range above 20 kHz, the question of whether the existence of such “inaudible” high-frequency components may affect the acoustic perception of audible sounds remains unanswered. In this study, we used noninvasive physiological measurements of brain responses to provide evidence that sounds containing high-frequency components (HFCs) above the audible range significantly affect the brain activity of listeners. We used the gamelan music of Bali, which is extremely rich in HFCs with a nonstationary structure, as a natural sound source, dividing it into two components: an audible low-frequency component (LFC) below 22 kHz and an HFC above 22 kHz.
Brain electrical activity and regional cerebral blood flow (rCBF) were measured as markers of neuronal activity while subjects were exposed to sounds with various combinations of LFCs and HFCs.

New Orleans, October 16, 2012 – You walk into a bar and music is thumping. All heads are bobbing and feet tapping in synchrony. Somehow the rhythmic sound grabs control of the brains of everyone in the room forcing them to operate simultaneously and perform the same behaviors in synchrony. How is this possible? Is this unconscious mind control by rhythmic sound only driving our bodily motions, or could it be affecting deeper mental processes? The mystery runs deeper than previously thought, according to psychologist Annett Schirmer reporting new findings today at the Society for Neuroscience meeting in New Orleans.
Rhythmic sound “not only coordinates the behavior of people in a group, it also coordinates their thinking—the mental processes of individuals in the group become synchronized.” This finding extends the well-known power of music to tap into brain circuits controlling emotion and movement, to actually control the brain circuitry of sensory perception. Project ARTEMIS. Project ARTEMIS was a project undertaken by the United States Navy in the 1960s, which produced a Low Frequency Active Sonar system that could detect submarines at long range. Robert A. Frosch, in his capacity as Technical Director of Hudson Laboratories (Columbia University), was Technical Director of the project.[1] Dr. Frosch later went on to be the 5th administrator of NASA. The project was named in honor of Frederick Vinton Hunt.
Since Artemis is the goddess of the hunt, the name of the project is in deference to F. V. Hunt who proposed the idea in 1951. Ship modifications[edit] A 500-shaft horsepower, controllable-pitch screw propeller was installed in a transverse tunnel through the forefoot of the USNS Mission Capistrano. Active array specifications[edit] The active portion of the Artemis array was 50 ft (15 m) by 33 ft (10 m) and weighed 400 tons.
