Abstract

Active noise control is a means of controlling the acoustic noise in real-time by generating antinoise. Therefore, computational complexity of an ANC algorithm plays a vital role in its implementation. The feedback ANC computes an extra secondary path estimate compared to the feedforward ANC and hence has more computational burden compared to the feedforward ANC. In this paper, a new frequency domain ANC algorithm is proposed that is computationally efficient compared to the standard time domain feedback ANC algorithm. The algorithm is made delayless and is suitable for real-time implementation.
