Safety at work is determined primarily by working conditions. The proportion of workers affected by noise, ultrasound and infrasound is very high. The developed classification of noise sources makes it possible to clearly define the main directions of scientific work in the field of acoustic equipment at pulp and paper enterprises., Безопасность труда на производстве определяется, в первую очередь, условиями труда. Доля работников, находящихся под воздействием повышенного уровня шума, ультразвука и инфразвука является очень высокой. Разработанная классификация источников шума позволит четко определить основные направления научных работ в области акустики оборудования ЦБП.

Рассмотрен инфразвук в качестве связующего звена между характеристиками космической погоды, климатом и биосферой Земли. Инфразвук рассмотрен как фактор, который является информативным параметром в регистрации природных и техногенных катастроф. Подчеркивается необходимость усиления роли космических аппаратов в исследованиях биосферы Земли путем регистрации инфразвука, Розглянуто інфразвук в якості сполучної ланки, яка здійснює зв’язок між характеристиками космічної погоди, кліматом і біосферою Землі. Інфразвук розглянуто як фактор, який є інформативним параметром у реєстрації природних і техногенних катастроф. Підкреслено, що необхідно посилення ролі космічних апаратів у дослідженнях біосфери Землі шляхом реєстрації інфразвуку, Infrasound as an element in communication between the characteristics of space weather, climate and biosphere of the Earth is considered. Infrasound as a factor, which it is as informative parameter in the natural and man-made disasters registration is considered. Emphasizes that, it is needed the strength increasing of the satellites role in the study of Earth's biosphere by recording the infrasound.A full analysis of the impact on the living world by infrasound during development of natural and man-made disasters or factors of space weather is impossible without special studies. It can help to check radiation levels of infrasound spacecraft. It determines the relevance of the present study.For the calculations of the characteristics of infrasound acoustic field monopole made up an algorithm and a program written in the language Fortran-4. The program consists of individual generated cycles. Calculations are performed assuming that the atmosphere with the infrasonic waves propagation, is homogeneous, layers are absent, the temperature is 20 degrees Celsius, and the sound velocity in the air in this case is340 m/ s.Acoustic waves attenuation in the air due to the presence of shear and bulk viscosity and also thermal conductivity impact.If we neglect the thermal losses, and also take into account that the bulk viscosity must be taken into account, as a rule, for high frequencies, then we can assume that the propagation loss of the traveling wave in the real environment due to the shear viscosity.The aim of this work was the research methodology development of infrasound interaction of space weather, natural and manmade disasters with the Earth’s noosphere.A factor that has a significant impact on the infrasound vibrations in the atmosphere is a seismic activity. And it can be an external impact on the preparatory processes and the result of it. Currently, there is a great need for the creation of systems that combine space and ground-based observations that accuratel

The authors have challenged the traditional theories of cardiac sound genesis and found out that cardiac sounds could be detected on carotid, ulnar and even femoral arteries, whereas it is harder to detect them in the thoracic wall zone. The authors have put forward a hypothesis of genesis of the 1st and 2nd cardiac sounds as a result of active oscillations of subendocardial fibers of the intraventriculat septum and the ventricles caused by organized pulses going via the His bands and in the node of Aschoff and Tawara. They also believe that the 1st and 2nd cardiac sounds function as circulation-organizing impulses, the 1st cardiac sound directs blood in the systole, thus debilitating arteriolar sphincters and perfusion of capillaries, while the 2nd cardiac sound debilitates and fills the ventricles with blood in the diastole. The heart itself operates as an acoustic endosonar

Проведен анализ данных натурных наблюдений за вариациями атмосферного давления и напряженности электрического поля в Геофизической обсерватории "Михнево". Показано, что в процессе развития полярных сияний могут возникать синхронные вариации давления и напряженности электрического поля в приземном слое атмосферы, а также характерные для развития магнитной бури изменения в напряженности электрического поля. Исследована взаимная корреляция этих величин, показавшая наличие связи между ними., The analysis of atmospheric pressure and electric field intensity variations field observations in GPhO "Mikhnevo" was carried out. It is shown that during the development of auroras, synchronous variations in pressure and electric field strength in the surface layer of the atmosphere, as well as changes in the electric field characteristic for the development of a magnetic storm, can occur. The cross-correlation of these values was inestigated, which showed a link between them.
