Vpliv frekvence zvoka na rezultate nestandardne meritve izolativnosti pred zvokom v zraku : zaključna naloga univerzitetnega študijskega programa I. stopnje StrojništvoKraner, TimotejV Centru za Eksperimentalno Mehaniko (CEM) je bilo razvito nestandardno preizkuševališče za merjenje izolirnosti pred zvokom v zraku. Vzpostavljena metoda merjenja posnema standardno meritev, a je ... izvedena na manjši skali. V skladu z vzpostavljeno nestandardno metodo merjenja se meritve zvočne izolativnosti izvajajo ob izpostavljenosti zvoku, ki združuje celoten frekvenčni spekter, torej belemu šumu. V realnem okolju pa zvok, kateremu smo dnevno izpostavljeni, izstopa v določenem frekvenčnem območju. Iz omenjenega je sledil cilj raziskave, to je preveriti vpliv frekvence zvoka na rezultate nestandardne meritve izolativnosti pred zvokom v zraku. Rezultati so pokazali, da na nestandardnem CEM preizkuševališču, frekvenca zvoka vpliva na rezultate meritev zvočne izolativnosti. Rezultati prikazujejo, da je izmerjena zvočna izolativnost ob viru zvoka določene frekvence višja ali enaka kot izmerjena pri belem šum. Odstopanja pa so odvisna od merjenega materiala in frekvence generiranega zvoka.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
