Investigation of Noise Parameters at Head Thresher Operation and Noise Map Development in Free Sound Field

Abstract

The article demonstrates the need to solve the problems connected with adverse acoustic impact on small tools and equipment operators of selective and seed-production process in plant breeding. Assessment method of the overall area of hazardous values of equipment noise characteristics in similar conditions and specialized device for carrying out acoustic research are described. The method to do research and to compile two-dimensional noise map by the example of head batch thresher is developed.

U radu je predstavljena potreba rešavanja problema povezanih sa štetnim uticajem buke na rukovaoce malih alata i opreme za proizvodnju semena. Opisani su metod procene opšte oblasti opasnih vrednosti karakteristika buke ispitivane opreme u sličnim uslovima i specijalizovani uređaji za izvođenje akustičnih ispitivanja. Razvijen je metod ispitivanja i sastavljanja dvo-dimenzionalne mape buke kroz primer vršalice.
