A simple active noise control in acoustic duct

In this paper we describe a very simple adaptive active noise control system (further only ANC system) in an acoustic duct, which is based on an evaluation module TMS320C701 EVM from Texas Instruments. As a digital filter we use FIR filter with implemented LMS algorithm and the achieved level of noise attenuation 18 dB when we use a tonal noise. This contribution is based on the diploma thesis of the first author, who is now a beginner PhD. student at the department mentioned below.
