Abstract

Ovaj rad opisuje mogućnosti poništavanja odnosno smanjenja razine buke, s naglaskom na aktivno poništavanje buke. Ukratko su opisane pasivne metode smanjenja buke, te osnovni principi kod metode aktivnog poništavanja buke. Zatim je detaljnije opisana osnovna adaptivna filtarska struktura i LMS algoritam. Implementacija sustava za poništavanje buke je realizirana na TMS320C6713 DSK, čija je arhitektura detaljnije opisana u radu. Na kraju rada prikazani su rezultati i mjerenja sustava za poništavanje buke, implementiranog u zadanom prostoru, gdje su akustički parametri prostora uzeti u obzir i također su prikazani u radu.

Abstract (english)

This paper describes the capabilities cancellation or reduction of the noise level, with a focus on active noise cancellation. A brief description of passive noise reduction methods, and basic principles of active noise canceling method. Then, as further described the basic structure of the adaptive filter and the LMS algorithm. Implementation of the system for noise cancellation is realized on the TMS320C6713 DSK, whose architecture is described in more detail in this paper. At the end of the paper are presented the results of measurements of noise canceling, implemented in a given space, where the acoustic parameters of space considered are also presented in this paper.
