Vpliv položaja mikrofona na napako merjenja ropota v kabini zgibnika Woody 140 : diplomsko delo - visokošolski strokovni študij - 1. stopnja = Influence of microfon position on noise measurement uncertainty in skidder woody 140 cabine : B. Sc. Thesis - professional study programmesDimnik, AntonDiplomsko delo je nastalo z namenom, da bi raziskali porazdelitev jakosti ropota v kabini zgibnika Woody 140. Ropot je bil merjen po kazalniku ekvivalentna jakost ropota (LAeq) in kazalniku konična ... jakost ropota (LCpeak), tako pri prostem teku motorja, kot tudi pri delovnih obratih motorja. Ugotovitve kažejo, da se jakost ropota v kabini razporeja nehomogeno ne glede na kazalnik, po katerem merimo ropot, in ne glede na število obratov motorja zgibnika. Najvišje in najnižje izmerjene vrednosti ropota po kazalniku LAeq se pojavljajo na različnih merilnih mestih v kabini, pri različnih obratih motorja. Najvišje vrednosti ropota po kazalniku LCpeak pri različnih obratih motorja sovpadajo. Najvišja odstopanja so izračunana pri delovnih obratih motorja, kjer so se izmerjene vrednosti za kazalnik LCpeak razlikovale do 6,41 dB(C), pri kazalniku LAeq pa do 5,23 dB(A). Znotraj območja merjenja ropota, ki ga predpisuje standard SIST EN ISO 9612:2009, so razlike v jakostih ropota večje od predvidenega odstopanja 1 dB. Iz dobljenih rezultatov lahko zaključimo, da postavitev mikrofona lahko značilno vpliva na oceno obremenitve z ropotom, ter da je potrebno mikrofon postaviti čim bližje ušesom delavcev.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
