A significant threat to critical infrastructure of computer systems has a destructive impact caused by infrasound
waves. It is shown that the known infrasound generations are based
on using the following devices: a Helmholtz Resonator, Generation
by using a Pulsating Sphere such as Monopol
ies, Rotor
-
type
Radiator, Resonating Cylinder, VLF Speaker, Method of Paired
Ultrasound Radiator, and airscrew. Research of these devices was
made in this paper by revealing their characteristics, main
advantages and disadvantages. A directional pattern o
f infrasound
radiation and a graph of dependence of infrasound radiation from
the consumed power was constructed. Also, during the analysis of
these devices, there was proven a set of basic parameters, the values
of which make it possible to characterize t
heir structural and
operational characteristics. Then approximate values of the
proposed parameters of each those considered devices, were
calculated. A new method was developed for evaluating the
effectiveness of infrasound generation devices based on the
definition of the integral efficiency index, which is calculated using
the designed parameters. An example of practical application of
the derived method, was shown. The use of the method makes it
possible, taking into account the conditions and requirem
ents of
the infrasound generation devices construction, to choose from
them the most efficient one.
