Priprava merilne škatle za ločeno merjenje hrupa sesalne enote : zaključna naloga univerzitetnega študijskega programa I. stopnje Strojništvo
Ravnihar, Neža
V tem delu je predstavljeno merjenje hrupa sesalne enote na strani, kjer zrak v enoto vstopa ter na strani, kjer zrak iz nje izstopa, z namenom, da se potrdi kako naj bi bila sesalna enota ...pozicionirana znotraj sesalnika prahu, da bi bil hrup le tega čim nižji. Meritev je bila izvedena znotraj merilne škatle, ki je bila skonstruirana tako, da je možno ločeno pomeriti prispevek hrupa elektromotorja (prevladuje elektromagnetni hrup) in prispevek hrupa turbokolesa, na katerem prevladuje aerodinamični vir hrupa. Ugotovljeno je bilo, da je raven zvočnega tlaka odvisna od lege opazovalne točke.
