’Hologram’ or ’3 dimensions cinema effect’ are well known expressions for almost everyone. This is an illusion of the visual area of the brain; whilst 3D picture is perceived, in spite of sight of 2D picture.
It is also possible to ’deceive’ the hearing area and not heard sounds can be heard. In this case, there is a today well known neurological Phenomena.
We are able to hear sound on that low frequency (e.g. 4 Hz) that is far under the human hearing threshold (approx. 20 ‑ 40 Hz), thus the hearing system would not be able to process it as sound stimulus; therefore, it is not heard by our hearing organ.
This sound comes into effect if you hear sound with different frequency in left and right side of the headset, and the frequency difference is very slight. So, one ear cannot hear what is heard by the other one. E.g. Sound with frequency of 440 Hz is on the left side, and sound with 444 Hz frequency is launched on right side. This time, - as this slight difference cannot be interpreted separately - , the brain perceives the frequency average of the two separately heard sounds (442Hz); accompanied by the sound which is the frequency difference (4Hz) of the two different, original sounds. This is defined as binaural beats.
This phenomenon was published by Gerald Oster, biophysicist, in 1973, in an article of a professional paper, called Scientific American. The article summarizes the related research in the previous 134 years. Since then, loads of papers are concerned with binaural beats, which is in the spotlight again.
If the brain is stimulated enough with this sound, with the binaural beats, then ’brain wave synchronization’ is realised on an identical frequency among appropriate circumstances (in an environment which is poor in stimuli, lying at rest, with closed eyes). Matter of the phenomenon is that the beats of different areas of the brain necessarily realign to the beats of stimulus (potency). Thus, for expample, if our potency is typical of the frequency at daytime wakefulness (20 Hz), that means the areas of brain similarly send out brain waves in line with compliant frequency, so they are stimulated, and we will be more wakeful. The potency of brain status is with low frequency (e.g. 4 Hz) during the deep sleep and,accordingly, this stimulates the brain to meditative, sleepwise status.
Speciality of our process is that this physiological effect has been integrated into light music during audio technical process. This music has been composed specially for this reason, it has been set by strict set of rules, in determined range of sound frequency ( Solfeggio Scale ). During the audio anaesthesia, the patient is given stimulation with 4 Hz frequency of binaural beats via playing music. This generates the ’delta brain waves’, typical of deep sleep of EEG; thus stimulating the brain to this type of synchronization, actually to get into meditative and sleepwise status.
