V diplomski nalogi so predstavljeni rezultati raziskave in analize primerjave obremenitve sekača z ropotom pri sečnji mlajših sestojev iglavcev z akumulatorsko (Makita DUC302Z) in bencinsko motorno ...žago (Makita EA320035B). Delo je potekalo na območju Vrhnike, v GGO Lj, GGE Vrhnika, v mlajših sestojih iglavcev, v katerih so bila drevesa že večinoma posušena. V raziskavo je bil vključen posek 30 dreves, in sicer posek 15 dreves z akumulatorsko in 15 dreves z bencinsko motorno žago. Rezultati raziskave so pokazali, da delo z bencinsko motorno žago povzroča večje obremenitve z ropotom po vseh merjenih kazalnikih in vseh delovnih operacijah. Tako je vrednost LCpeak za 2,2 dB(C), vrednost LAIeq za 13,2 dB(A), vrednost LAeq za 12,9 dB(A) ter LAeq.kor za 13,1 dB(A) pri delu z bencinsko žago višja kot pri delu z akumulatorsko motorno žago. Kljub temu je ocenjena dnevna izpostavljenost ropotu pri delu z akumulatorsko motorno žago pokazala, da so opozorilne vrednosti, definirane v slovenski zakonodaji, še vedno presežene. Posledično je uporaba glušnikov pri delu z akumulatorsko motorno žago obvezna.
