Traffic noise annoyance in dwelling area like private houses and apartment is becoming very important issue nowadays in South Korea and need to be solved. In this paper frequency analysis of the traffic noise near highways was performed. Based on sound pressure levels analyses and theirs frequency content specific requirements for component of active noise control systems are formulated. Active compensational loudspeaker, microphone front end and DSP design were analysed, considered and proposed. Required components specifications and design solutions for electro-acoustic hardware are verified using experimental technique.

Keywords: noise barrier, noise levels, ANC (active noise control), active loudspeaker, DSP platform, adaptive algorithms.
