Biomechanical mechanisms of action of low-frequency acoustic vibrations on a person

The aim of this work to substantiate the mechanisms of action of low-frequency acoustic vibrations on humans, caused by mechanical interaction of acoustic oscillations with the anatomical structures of the body. One of the modern features of industrial noise is the domination noise spectrum of the low frequency noise and infrasound with high intensity. To characterize these ranges, the scientific literature uses the term low-frequency acoustic oscillations, due to similar physical properties and biological effects on the human body and animals. It is proven that infrasound has negative effects on many organs (respiratory, hearing, vision, etc.) and human systems (central and autonomic nervous, etc.) and leads to the development of diseases, including professional (sensorineural hearing loss, vestibulopathy, autonomic disorders). On this basis, infrasound is included in the list of harmful production factors. A number of biological effects is formed by a direct mechanical interaction of acoustic oscillations with the anatomical structures of the human body. The length of the acoustic wave and its intensity are decisive parameters for the formation of a reaction in the human body. The interaction of low frequency acoustic oscillations with the anatomical structures of the body must be considered as the interaction of two mechanical systems that leads to the development of various physical effects in tissues and organs (diffraction, resonance, elastic waves, cavitation, etc.). The latter are the basis of the direct action of acoustic oscillations and lead to anatomical damage of the tissues, a conformational disturbance of cellular structures and macromolecules, activation of receptors (mechano-, proprio, vestibuloadaptive, etc.). Biomechanical effect of low-frequency acoustic oscillations should be taken into account in the normalization of low frequency sound range, and determining ways and means of protection from low-frequency acoustic oscillations not only the organ of hearing and the head and internal organs.
