Abstract
This scientific work presents results of energy-efficient lighting systems based on mirrored hollow tubular light guides tests when sound waves of various intensities of low-frequency, mid-frequency and high-frequency ranges pass through them. In addition, technological changes in design of natural lighting systems, which were carried out in order to increase their vibration resistance and noise absorption are shown.Studies have shown high reliability of lighting systems in terms of their soundproofing, especially in mid-frequency and high-frequency ranges, which can significantly reduce harmful effects of noise on human body, leading to fatigue, depletion of brain cells, insomnia, decrease in overall working capacity and human productivity. Conclusions of this work make it possible to further optimize the future prospect of widespread use of energy-efficient lighting systems based on mirrored hollow tubular light guides in construction of residential, administrative and industrial premises.
