Avtonomni sistemi za klasifikacijo virov hrupa na osnovi prostorskega filtriranja : doktorsko delo

Murovec, Jure, 1990-

V tem doktorskem delu so predstavljeni rezultati raziskav, ki so omogočili razvoj napredne metode za merjenja hrupa. Postavljene so bile osnove za znanstveni preboj pri razumevanju človeške ... percepcije zvoka in razvoj aplikativnih metod za merjenje ter spremljanje hrupa z namenom izboljševanja življenskega prostora in razvoja okoljsko bolj sprejemljivih strojev ter naprav. Neposreden rezultat novih znanstvenih dognanj je štirikanalna mikrofonska antena z optimizirano geometrijo in novimi pripadajočimi algoritmi, s katerimi dosegamo razmerja signal-šum, ki presegajo vse komericalne sisteme za detekcijo smeri zvočnih virov. Z algoritmi smo poizkušali posnemati človekovo sposobnost prostorskega filtriranja akustične okolice. Ker smo se želeli čimbolj približati merilčevim dejanjem in slediti trendom meritvam hrupa v okolju, smo uporabili psihoakustične značilke, saj direktno opisujejo človeško dojemanje zvoka. Meritvam hrupa smo vpeljali pojem usmerjenosti imisije. Razvili smo tudi učinkovitejši algoritem za detekcijo smeri prihoda zvoka ter predstavili modificirano rastočo samoorganizirajočo mrežo, s katero samostojno klasificiramo zvočne dogodke. Prototipni sistem je bil preizkušen v realnem okolju.
