Abstract

Tema ovog diplomskog rada se temelji na teoretskom pristupu iskoristivosti i mogućnosti korištenja aktivnog sustava zaštite od buke u prostoru sa rotacijskim tiskarskim strojem. Interakcijom zvučnih valova, buke i proizvedene protubuke, dolazi do međusobnog poništavanja tlakova što dovodi do efekta smanjenja neželjenog zvuka. Kako bi do toga došlo, zvuk je potrebno registrirati (mikrofon), definirati parametre i obraditi (računalo), te reproducirati protufazno (zvučnik). Razvojem elektronskih sustava ovakvi sistemi redukcije od buke preuzeti će vodstvo pasivnim metodama, u domeni zaštite od buke, zbog isplativosti, iskoristivosti i ekonomičnosti.

Abstract in english:	The topic of this paper is a theoretical approach to feasibility of use of active electronic noise control systems in work spaces with rotational printing machines. Interaction between the sound waves of unwanted noise and artificially produced ‘anti-noise’ results in a mutual cancellation of sound air pressures and a great reduction of unwanted noise. In order to achieve this, the unwanted noise needs to be recorded with a microphone, analysed through a computer and played back phase-reversed through a speaker. With further technological developments, specialised electronic noise control systems will replace many passive methods of noise control due to their better usability, feasibility and cost effectiveness.
