Intense Noise

The generated noise of the Mi-8 helicopter will differ significantly in the mechanism of formation, resulting in a complex spectrum. Working conditions inside the helicopter correspond to harmful working conditions in terms of noise (class 3.2 – 3.3), and in terms of infrasound – acceptable (class 2). The simultaneous effect of intense noise, infrasound and General vibration creates high risks to the health of helicopter personnel.
