RESEARCH AND DESIGN OF ADAPTIVE FILTER FOR ACTIVE NOISE CONTROL SYSTEMS (ANC)

Abstract

The Active Noise Control (ANC - Active Noise Control) is new solutions to
increase audio noise protection, create quiet spaces, improve the quality of life.
The principle of ANC is to produce an active sound wave which can reduce sound
energy between the frequency range from a few tens Hertz to several hundred
Hertz. In this paper, we will present an adaptive filter configuration that is
applied to ANC systems. The adaptive filtering algorithm of the ANC system on
Matlab & Simulink has proven the effectiveness of the proposed configuration.
