This method will be the basis for an improved scientific research in the understanding of human sound perception and the development of applied methods for measuring and monitoring noise, with the aim of improving the environmental habitat and development of more acceptable machinery and equipment. The direct result of new scientific findings is a four-channel microphone antenna with optimized geometry and new associated algorithms with which we achieved signal-to-noise ratios that exceed all commercial systems for detecting the direction of sound sources. As we wanted to mimic human actions and track trends of environmental noise measurements, we used psychoacoustic features because they directly describe human perception of sound. We introduced the concept of immission directivity. We also developed a more efficient algorithm to detect the direction of sound arrival and introduced a modified growing selforganizing map for classification of different noise sources. The prototype system was tested in a real environment of noise measurements"},{"@xml:lang":"sl","#text":"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"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"visokošolska dela"},{"@xml:lang":"en","#text":"theses and dissertations"},{"@rdf:resource":"http://www.wikidata.org/entity/Q1266946"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-4ZVU9J5P","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-4ZVU9J5P"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-4ZVU9J5P/594c7b-16d24-24166c98--8dbf36dd97e52/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-4ZVU9J5P/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-4ZVU9J5P"}}}}
