Multichannel Active Noise Control Systems and Aigorithms for Reduction of Broadband Noise
Active noise contral systems for braadband noise reduction require substantial computing power, especially for multichannel systems and adaptive controllers. Furthermore, speed of convergence can be an issue as weil. In this paper, methods and techniques are described that are able to reduce the computational complexity and to improve the speed of convergence. The latter is accomplished by usin...
متن کاملA High Performance Feedback Active Noise Control System
In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...

متن کاملPlants Role in Noise Reduction of Interior Walls (Comparison of Noise Absorption in Native Species and Non-Native Species)
Noise pollution is one of the most important features of architectural spaces having a great impact on the comfort of residents. Therefore, providing appropriate and sustainable solutions for noise pollution control is essential. Today, with the use of man-made synthetic materials, it has been tried to improve the sound performance of buildings. The purpose of this study is to show the characte...
متن کاملMultichannel active noise control algorithms using inverse filters
1.0 Introduction For active noise control (ANC) systems, a common approach is to use adaptive FIR filters trained with the filtered-x LMS algorithm [1], for both feedforward systems and Internal Model Control (IMC) feedback systems, in monochannel or multichannel systems. Variations of the algorithm sometimes called the modified filtered-x LMS algorithm have been published [2], which can achiev...
