Among the variety of oscillatory motion, the man most closely in contact with the low-frequency vibrations.In general, the classification adopted in the physics of low-frequency oscillatory processes, and that, based on a person's ability to feel the vibrations in the form of sound.According to this classification, sound, and other oscillations are divided into:
- infrachastotny (infrasound) range, where there are vibrations with frequencies up to 10 Hz;
- sound range, varying from 15 to 100 Hz;
- ultrasonic range, with fluctuations of more than 1 kHz.
most widespread fluctuations in the audio range, and not just because we have them can often be taken with the help of other senses, especially hearing.Moreover, it should take into account the fact that the feature of human perception of vibration phenomena in general, is that they selectively perceive our body, it is a function of frequency.That is, if one frequency we can perceive through hearing, the other frequencies have affected vision, vestibular system, circulatory system, etc.
In view of the circumstances of low-frequency oscillations become the subject of scientific interest representatives of various sciences: physics, astrophysics, wave studies, military affairs, and even the theory of historical fluctuations.
representatives of some trends in science, technocrats, argue that low-frequency vibrations, the use of them has a place only in the field of man-made man-made, technologies.Others believe that the universe itself, including social life, and are low-frequency vibrations originating seen in the existence of certain general laws of being (dialectic).
a complete list of all of these views simply do not need, but that show the most unexpected aspects of life, where the low-frequency vibrations manifest themselves, we will try.
A certain middle place was taken by representatives of the integrated knowledge, which saw the source and the process of our development in action forces the properties of space.They argued that civilization develops cyclically, that is, makes low-frequency oscillations, in which the period is 12 years (by analogy with the period of pulsations of the galactic origin).Therefore, every 12 of the world there is something crucial.When, for example, has built a temporary model of the Soviet system: 1893 (first year of the creation of the Bolshevik circles), 1905, 1917, 1929, 1941, 1953, 1965 (attempt to reform Kosygin), 1977 (the program "developed socialism")1989 ... I think that most of the dates shown in this list, there is no need to understand.This concept has not received serious scientific recognition, but at the level of mass perception, these "low-frequency oscillations," a very lively discussion, even in serious press.
Another, perhaps the most notorious example of where these processes are widely used, can serve as military affairs.Even in the nineteenth century, the great German microbiologist Robert Koch argued that such a time will come when man will have to fight with low frequency events such as the plague.It is difficult to say now how it was perceived by some of his statements.Most likely, some interpreted it as a warning.But there were also others who might have taken it as a hint.As a result, humanity is now on the verge of creating a weapon compared to which nuclear can not be perceived worse than the American comics.
It is about creating such means of destruction, which acts as the main factor affecting the sound, the noise in the physical context - the low-frequency vibrations of infrasonic range.According to some experts, if such weapon is created, it will be a truly ethnic weapons.Already there are specific development of such weapons - of "Love" and "channel".The prospects for their further improvement could be creation of weapons, the aim of which is the genetic apparatus of entire peoples.
Today really emerging technologies use low frequencies are widely used in industrial production.Due to technology and even fashion interests, they in such areas as vibration processes.
In a short article it is impossible to list all the scope and the specific problems that are solved technologies based on the use of low-frequency phenomena.Obviously the other - the use of low-frequency processes is not just a subject of increased attention from the scientific community, but also the direct economic factor of development and, as has been shown above, the factor of military-strategic.As for the role of low-frequency processes as an economic factor, I think, sufficient to give an example: in our days in the total cost of a modern ship, 20 to 30 percent of all costs absorb the cost of providing sound insulation.
