THE OUTPUT OF THE DEPENDENCY OF ACOUSTIC IMPACT OF DOMESTIC SOURCES IN THE CRANE CABIN ON RAILWAY TO THE COURSE
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2019, Vol 0, Issue 3
Abstract
Crane cabins on the railway track, as well as the majority of the cabins of vehicles, are thin-walled box shell rectangular profile, inside which is the workplace of the crane operator. The study of the process of noise formation in the cockpit at the workplace of the crane operator is carried out under conditions when the main sources of noise are broadband emitters, sound pressure and sound power from various sources are determined by the principle of energy summation, the closed volume is characterized by an average sound absorption coefficient. Noise characteristics inside the cabin are formed due to the simultaneous impact of air noise sources (internal and external) and structural noise transmitted through the frame to the elements of the cabin fence.
