NOISE EMISSION PROCESS MODELING BY OVERHEAD CRANES IN PRODUCTION AREAS

The aim of this work is a theoretical study of noise emission processes created by total acoustic system of overhead cranes in production areas. The paper provides analytical dependencies of sound pressure levels at industrial personnel workplaces. The expressions of octave sound pressure levels take into account the acoustic characteristics of the main sources of the cranes themselves and the parameters of the production premises.In the derivation of theoretical dependencies the main methods of technical vibroacoustics were used. The results of the study are the basis for selection of engineering solutions to ensure sanitary norms of noise in industrial areas.
