Classical active noise control systems are designed to minimise, in a sense, the residual signal at the microphone providing information about acoustic noise and secondary sound interference. The secondary sound operates at the same time on the acoustic noise at other positions including user ears. In the worst case this can result in sound reinforcement at those positions. In many applications placing...
The aim of the paper is to present main aspects of a research project on active noise reduction being performed at the Computer Control System Group, which is a part of the Institute of Automatic Control, Silesian University of Technology, Gliwice, Poland. In particular, the following problems are dealt with: higher order spectra in off-line and on-line identification of electro-acoustic plants for...
