Aktivno dušenje hrupa na primeru prezračevalnega kanala : [Prešernova nagrada]Černetič, Jan, 1982-Pričujoče delo obravnava preizkus praktične uporabe zančne strukture aktivnega dušenja hrupa v prezračevalnem kanalu. Pri izvedenih preizkusih je bila opazovana učinkovitost enostavnega analognega ... sistema za aktivno dušenje hrupa brez uporabe elektronskih filtrov. Učinkovitost je bila izmerjena v frekvenčnem območju pod 500 Hz, opazovani pa so bili naslednji vplivi: postavitev sekundarnrga vira relativno glede na mikrofon, sočasna uporaba absorbcijskih materialov in prisotnost stoječega valovanja. Izvedena je bila posebna meritev, kjer je bil približno ocenjen fazni odmik signala s pomočjo merjenja vmesne razdalje med sekundarnim virom in mikrofonom, ter sočasnim merjenjem hrupa višjih frekvenc v nestabilnem območju delovanja. V ožjem frekvenčnem pasu smo dosegli skupno raven dušenja 18 dB, največja raven dušenja pa je znašala 22dB.Type of material - research project ; adult, seriousPublication and manufacture - Ljubljana : [J.
