[Impulse noise at shooting from small arms and close combat weapon as the factor of military work].

The high-intensity impulse noise which is basic source in Armed forces are the firearms, has an adverse effect on professional soldiers, leading to decrease of professional working capacity and health deterioration. Due to influence of this factor the considerable part of military men has a hearing impairment and other diseases, including an arterial hypertension. The basic directions of protection of men from impulse noise are: perfection of hygienic rationing, optimization of the using of antinoise earphones, development of new generation of means of individual defense from noise.

[Hygienic estimation of combined influence of noise and infrasound on the organism of military men].

Hygienic estimation of combined influence of noise and infrasound on the organism of military men. Combined influence of noise and infrasound is accompanied by essential increase of risk of development neurosensory deafness and hypertensive illness. At combined influence of noise and infrasound with a maximum of a spectrum in the field of a sound range the probability of development neurosensory deafness will prevail.

[Medical and biologic evaluation of individual noise-protection means efficiency].

In laboratory and nature, the authors studied protective properties of experimental models of noise-protection earphones with high acoustic efficiency in broadened frequency range. The article covers expedience of studies at workplaces, including medical and biologic methods that evaluate noise-protection in audible and infra-sound ranges.

[Modern concepts and methodology of means, methods of protection, and safety measures for servicemen affected by nonionizing radiation].

The given information classifies the protection means and methods containing the known for today and prospective decisions, as well as process elements of development, creation and testing of these means Presented as whole, these protection group comprise all the possible aspects of the service-men safety problem in operation of military equipment objects, being the source of non-ionizing radiation.

[The psychological status of workers subjected to noise exposure].

Mental health was examined in workers from a reinforced concrete plant and a thermal electric power station who were exposed to intensive noise at work. Noise was shown to have an adverse effect on their body's function. Higher occupational doses were found to result in the asthenic syndrome, to impair psychic processes along with the most profound emotional and volitional changes.
