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 (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.
