Notice of Violation of IEEE Publication Principles - Active noise control for industrial applications

Abstract

In this paper we will show the construction of acoustic active noise control in hear defenders by the help of Filtered-x Least Mean Squares structure and using a low power fixed point digital signal processor. This system is implemented for 20dB to 30dB attenuation of broad band noise and ca 60dB for sinusoidal interference. This is well suited for industrial applications.
